Heather develops an attraction towards Alejandro during the beginning of Total Drama World Tour, and as the season continues, Alejandro begins to reciprocate said feelings. While most of the girls are smitten with Alejandro, Heather is the only one to be fully aware that he's manipulating them, and denies sharing any of the same kind of attraction. Both, however, respect each other for being strong competitors. Alejandro often compliments and flirts with Heather, noticeably more so than he does with other female contestants, to which Heather often responds with disgust and expresses frustration about his strategy in the game.
As the season progresses, Heather begins to fall for Alejandro with much deeper feelings than the other girls, and Alejandro, in turn, starts falling for Heather. By the end of Total Drama World Tour, it is clear that Heather and Alejandro have the same feelings for each other, despite their strategical conflict throughout the game. Both make it to the final two in Hawaiian Punch, where they confess their feelings for each other, and share their first kiss. However, Heather (well-known for her greed and countless amounts of betrayals) betrays him by kneeing him in the groin and tossing him off of the volcano, saying that "boys are okay, but a million dollars is way better!"
Prior to Total Drama All-Stars, Heather reveals that her relationship with Alejandro is over and claims that she has forgotten about him. In reality, Alejandro is still recuperating from the injuries he suffered at the end of Total Drama World Tour and resents Heather for it. The two of them are placed on the same team, where they continue arguing. Despite this, both Alejandro and Heather are shown to harbor feelings for each other, although they both continue to deny it. By the sixth episode, they both try to eliminate each other, with Alejandro coming out on top. Heather convinces everyone to vote for Alejandro, but he steals her idol and eliminates her. They officially become a couple somewhere after his elimination and before The Final Wreck-ening. When they appear in the finale making out and mostly resolving their differences. Though, after it's revealed the million dollars is up for anyone, they go back to their old habits.
Heather is mad at Alejandro in the episode because she thinks he is going to replace her and all of the other Total Drama cast members with the "Total Drama Dirtbags" cast. Their first one-on-one interaction is during the climactic high-speed bus chase scene when Alejandro tells her that she'll regret messing with him. She replies with a laugh, telling him that he messed with the wrong reality show cast. Later, when fifteen members of the cast along with Sierra are rescued and brought back to the craft services tent, Heather asks Chris about Alejandro and his role in "Total Drama Dirtbags" to which Alejandro raises an eyebrow with an otherwise unamused look.
In the opening sequence, Alejandro helps Heather climb onto the crown of the Statue of Liberty. Once she reaches the top, he flashes a grin at her, while she glares at him in response.
In the confessional, Heather states that she can see right through Alejandro and his "tactics," and then states that he looks like a threat to her. She also becomes embarrassed and aggravated in the cockpit confessional when Chef rambles on about Alejandro's attractiveness, making her switch to the bathroom confessional in order to ignore him. When returning to her rant, Heather ends up calling him "Ale-whatever."
Heather seems to be growing an attraction for Alejandro during the episode, as seen by several of her confessional comments. An example is when she calls him "perfect," which she regrets saying after asking herself what Alejandro's deal is, before grunting out of aggravation. Alejandro also blows a kiss at Heather, in response to her sticking her tongue out at him after successfully taking Sierra from his team for Izzy. Heather finds this somewhat shocking and flattering, but quickly gets a hold of herself and ignores him. In the final confessional of the episode, Alejandro specifically states on his villainous nature by stating "compared to me, Heather's a saint," knowing of her previous actions in particular.
Heather blocks Alejandro's attempt to stay on Sierra's good side with snacks he brought from first-class and has Sierra think of Alejandro as the enemy. In the confessional Alejandro is impressed by Heather's play, as Sierra was Chris's "favorite" and having her loyalty would also allow her to have control over Chris. He finishes by saying "she's good."
Moments after, Heather and the rest of Team Amazon emerge from the same pipe. Later in the challenge, Heather confronts Alejandro over what he did to Sierra, but he keeps flirting with Heather in response. As payback, she switches Alejandro's baby carriage that contains Noah in it with an actual baby carriage containing a real baby to sabotage them. Team Chris Is Really Really Really Really Hot ends up making it to the finish line, but realizes what Heather had done, so thus, they have to run back and swap the carriages again in order to regain Noah and the correct carriage. When the team returns, however, they realize that they have lost and Heather's team has already won. Alejandro nods his head at Heather, acknowledging that her plan is good. However, once it is announced that the challenge is a reward challenge, Heather becomes angry, and even more so when Alejandro blows a kiss at her.
Leshawna accuses Heather of being jealous, because Alejandro is paying more attention to her, to which Heather then insists that she dislikes him very much. Despite this, Heather is shown throughout the episode to be visibly upset with Alejandro flirting with Leshawna. Alejandro's strategy seems to work well when Leshawna starts beating up Heather, but then becomes concerned, and purposely loses the challenge to make sure that she is okay. In Heather's final confessional of the episode, she starts to compliment him, before cutting herself off mid-sentence, realizing what she had said. Towards the end of the episode, Heather demands to know why he took a dive, though Alejandro avoids the question by flirting with her again which she is clearly annoyed by.
When Team Amazon attends their very first elimination ceremony, Alejandro sneaks up to Heather, who is sitting at the very end of the bleachers, and away from the others. He tries to cheer her up with fake sympathy, stating that the game will be so much easier for him after her departure. Heather, unfazed by the insult, reveals that she knows that Alejandro manipulated Leshawna, and possibly Bridgette. She then threatens him, stating that he is lucky that he didn't attempt to fool her. Alejandro then smugly replies by telling her that, with the temptation of a kiss, even she couldn't resist him forever. Both parties lean closer to each other until Heather arrogantly declares she would have crushed him. Alejandro is taken aback by Heather's comment, but before he can speak further, Chris begins the ceremony and Alejandro vanishes. Later, after Heather is saved from elimination, due to the challenge being a non-elimination, she states in the confessional that after making her teammates pay for their attempt to vote her off, she will crush Alejandro for dessert.
At the beginning of the episode, both Heather and Alejandro are sitting in the economy-class section with their teammates. Heather sarcastically asks Alejandro if he is having trouble controlling his team in order to irritate him. He smugly calls her attempt to anger him "cute." Heather replies by stating that her team is strong and never gets distracted by boys. Alejandro then smirks before pointing at Sierra, who is on the floor sobbing over Cody voting against her, eating straight from an ice cream tub with her hands.
At the beginning at the episode, Heather is seen crawling into the air vents for no apparent reason. Courtney states that if she didn't know better, she would have thought that Heather had a crush on Alejandro. Both she and Gwen make fun of Heather by stating that she is "in love," but Heather angrily insists that she isn't. Afterwards, Heather is lurking around in the vents to gather information, and see if Alejandro's team is trying to make an alliance with DJ, who is the only remaining member on his team. After hearing of DJ's plans to lose the next challenge, she accidentally falls out of her hiding spot, and Alejandro teases her by asking her if she is spying on them. Heather denies the accusation and covers it up by stating that she had merely dropped her pen and that she is "just scribbling."
Later on, Heather gives DJ a cushion from first-class that she carried out of the plane so he wouldn't drown, and asks him for an alliance. Alejandro is shocked, and asks Heather why she's asking him now. Heather replies by calling him jealous, but Alejandro merely says that she would have asked for an alliance before giving him the cushion, as a form of bribery. Heather realizes her mistake, and in the confessional, states that Alejandro is "good," letting out a romantic sigh. However, she quickly notices what she has done and demands that she gets the tape back, not wanting her feelings for Alejandro to be seen. When Heather gets DJ to the second part of the challenge before anyone else, Alejandro compliments her, calling her "ambitious one." While eating, Alejandro discovers Heather put Owen's socks in the clam chowder his team won. He is then seen in the confessional brushing his teeth and ranting the words "Malvada bruja! Malditos incompetentes!" which roughly translates to "Wicked Witch! Damned incompetent!"
In economy class, Heather complains about Alejandro, and how he is probably making DJ feel welcome in first class, calling him a jerk. Right before Heather takes a dive into the water, Alejandro compliments her perfect diving form. This causes Heather to lose focus and land hard on the water. He apologizes in a teasing tone, and she growls back at him as her body sinks into the water. When Alejandro saves Gwen from the eels and takes the gold from her, Heather runs up to him and snatches it back, causing him to yell in surprise, and Heather to apologize in the same teasing tone he had used previously. Unlike Heather's reaction, Alejandro states that he deserved it, smiling. Heather smirks at Alejandro later on and asks him how it feels to be "toast" when his team gets behind in the "Bobsled of Death" challenge. Alejandro retorts by stating that he didn't know, as he hasn't been "toasted" yet.
At the beginning of the episode, Heather notices that Alejandro is missing when she and the rest of the cast are on the double-decker bus. After Chris announces he was caught by Jack the Ripper, Heather asks Courtney and Gwen if they thought he is okay, showing concern over his disappearance. However, she quickly adds that his absence is good for her team, covering up what she said earlier. She then asks if they should try and find him, but Gwen and Courtney just laugh the idea off.
After Chris leaves the common area, and announces that they are recreating the Olympics in Greece, Alejandro and Heather begin to taunt each other about their teams' superiority. When Heather slaps her forehead after Sierra attacks Courtney, Alejandro mocks Heather on her inability to control her team. Later on in the episode, Chris states that because Alejandro and Heather have not yet competed, they have to compete against each other in a hurdles race. Heather shoots Alejandro a smug smile and brags about how she is very flexible. To her surprise, Alejandro proves to be more flexible than her by splitting his legs apart while tying his hair in a ponytail with his feet. As they compete, Alejandro taunts Heather and shows off during the race while she looks at him in annoyance, including running backward and walking on his hands. Eventually, Alejandro loses concentration and crashes into a hurdle, which costs him the race and earns Heather the victory, which causes her to cheer victoriously.
In the economy class section, Alejandro begins to talk to Duncan and Owen about how Team Amazon is only powerful because of Courtney and Heather, and begins to plan ways to break them apart. Later on, Heather starts to get annoyed by Alejandro when he flirts with Courtney, but she figures out his plan eventually and attempts to flirt with Duncan to get back at him. Courtney later asks Heather if there is anything going on between Alejandro and her, resulting in Heather quickly denying the suggestion, regardless of the fact that she is visibly upset with Alejandro flirting with Courtney. Later on, Alejandro is shown to be perplexed in the confessional, when he witnesses Heather flirting with Duncan. He begins to worry, stating that Heather has never used flirtation before, but then assures himself that she isn't really in love with Duncan. He then adds that she did not have "true passion" in her eyes when doing so, though he did not seem entirely convinced by that. When Heather helps Duncan up and flirts with him again, Alejandro is visibly upset, as he gasps in surprise before quickly turning his head the other way. He tries to focus less on Duncan and Heather, and more on the game along with seducing Courtney.
At the beginning of the episode, Heather is jealous of Alejandro's flirting with Courtney and tries to get his attention by saying that she must have accidentally sat in gum, thus trying to get him to look at her butt. However, Sierra ruins this by repeatedly telling her that there is no gum, obviously not getting the hint. Heather becomes jealous again when Alejandro hugs Courtney for warmth, and she tries to counter this by hugging Duncan but fails due to the fact he misses Gwen. She later stares in admiration at Alejandro after he removes his shirt during the challenge, distracting herself from focusing on the task at hand. Just before the elimination ceremony, Heather confronts Alejandro in the cargo hold, asking what his deal is with Courtney. He tells her that it's all strategy, and the only woman he could ever look at is her. He then holds her head lovingly, leaving Heather dazed and smiling. They gaze into each other's eyes for a moment before Chris's intercom announcement of the upcoming elimination ceremony interrupts them. Before leaving, Alejandro asks Heather to go ahead and vote Courtney off. Alejandro then makes a confessional explaining his "plans," accidentally revealing that he actually has feelings for Heather. In response, he nervously denies it.
After Sierra tries to reject Alejandro for winning him as her "husband," Heather goes up to him and helps him off the ground, pairing herself with Alejandro. While Alejandro tries to give Heather directions to get to her wedding dress, Heather complains and eventually gets there. Although Alejandro cheers excitedly that they've won, Heather complains that he did not give her good directions. After Alejandro helps Courtney get to her wedding dress, Heather complains in the confessional that Alejandro is supposed to only have one bride, meaning herself. When Chris announces that Heather and Alejandro get a head start in the second challenge, Alejandro calls her "Mrs. Alejandro" while Heather calls him "Mr. Heather" in return. As they are about to cross the tightrope, Alejandro calls Heather his "better half" and scoops Heather into his arms bridal style, with Heather expressing satisfaction. Halfway across the rope, Heather and Alejandro fight about who to vote off next, and she causes them to fall and lose the challenge. Alejandro later reveals that he fell on purpose as a strategic move, not wanting to appear too strong a player.
At the beginning of the episode, Heather and Alejandro are sitting together with Cody, debating over whether or not Sierra and Cody are actually married. Heather claims they are married just about as much as he is to her, and Alejandro claims, yet again, that Heather is attracted to him, but says that marriage is "rushing things." Heather is disgusted by his comment, but he thinks her eyes say otherwise. Later on, during the eating portion of the challenge, Heather tells on Alejandro, Blaineley, and Courtney for cheating during the game. Back on the plane, Duncan believes that Alejandro would vote for Heather for ratting him out, but Alejandro says that Heather only did that because she wants Blaineley out, so he'll help Heather vote for her. Finally, at the elimination ceremony, they are seen sitting together. When Blaineley begins to rant about each of the contestants, she tells Heather and Alejandro that they should "just give it up and make out already." They exchange surprised and confused glances before Heather angrily asks Chris to get rid of Blaineley.
Throughout the episode, both have a running gag of speaking at the same time, which irritates the two of them greatly. At the start of the episode, after Alejandro notices Duncan's sudden happiness, Duncan says, "Speaking of failed romance..." teasing Alejandro and Heather, suggesting that he should go in the common area so that the two could start "building their nest together." In response, both Alejandro and Heather retort at him in the same tone and with the same words. Once Duncan sees this, he starts laughing, stating that "Blaineley was right! You two are so lame for each other," much to their shock and dismay. For the first part of the challenge, Heather and Alejandro manage to knock out Duncan with soccer balls and cheer at the same time, much to their annoyance. When it is Heather's turn to grab the African Plums, Alejandro is the first to kick a soccer ball at her, but he misses at first, leaving Heather to say, "I knew he wouldn't kick a ball at his crush," in a taunting manner. The soccer ball then manages to come back and hit her in the face. During the second part of the challenge, after Duncan fails to break his gourd at first, Chris comments at Heather's batting skills, calling her "Alejandro's girlfriend", which causes her to hit the plum backwards and onto Alejandro's head. After the plum hits his head, Chris grins, stating "Oh yeah, they're meant for each other", to which both of them retort at the same time, again.
This causes Alejandro to point out that it is ridiculous that he and Heather are speaking at the same time. For the last part of the challenge, when the contestants must hunt down Ezekiel, Alejandro brings Heather and Duncan into a huddle, in which Alejandro manages to steal Heather's tranquilizing balls after she states she's going to do the challenge alone. Once Heather notices her tranquilizing balls are missing, she growls Alejandro's name before running away from a lion. During the song, Alejandro and Heather taunt each other. Shortly after the song, they form an alliance to kick everyone off the show, leaving them for the final two, though they speak at the same time again, much to Heather's annoyance. They plan Duncan's elimination and Heather is quite astonished at Alejandro's ruthlessness. Once the plan works, Heather and Alejandro hug each other and then smile at each other warmly before realizing how close they are and quickly get back.
Once in the elimination room, Chris grins at Alejandro and Heather while commenting, "tension-y." When Chris notes that there is one vote for both Alejandro and Heather, both of them offer suspicious glares at each other. After Alejandro picks Cody to go into first-class with him, Heather is greatly angered by this and complains about him breaking the "fake alliance". She then intends to take him down.
In the beginning of the episode, Alejandro plots against Heather by having Cody and himself vote her off the show. Once the plane lands on their next destination and manages to knock down a stone statue, Heather states that it's "not the only chiseled rock that's going down today," to which Alejandro takes it as a compliment, catching Heather's slip up before quickly covering it by saying "grizzled" and arrogant. During the first part of the challenge, when Sierra starts kissing up to Heather, in the confessional, Heather states "Alejandro's going down" if Sierra is willing to make an alliance to vote him off the show. Though afterwards, she puts on a miserable look, implying that she could regret it later on. As Sierra and Heather do the first part of the challenge together, Heather calls Cody a loser for "cozying" up to him, while Sierra smartly replies "and if falling for Alejandro makes someone a loser." This makes Heather deny their attraction again, though Sierra gets her to relax as they plan to vote off Alejandro together. For the second part of the challenge, after Alejandro remarks at the female condor being "two Alejandro's wide," Heather says in the confessional that one Alejandro is enough, though she says two wouldn't be bad if one of them was nice and would not try to defeat her all the time.
When Heather says "she likes her eyes" after Alejandro states condors can rip out human eyes, he says he likes them too, especially when they're "shooting daggers." She glares at him, to which he adds "yes, like that." When the condor flies towards Heather during the song, Alejandro (along with the others) shield their eyes, implying that they don't want to see her get maimed by the condor, though after she victoriously remarks she'll be in the final three, he and the others glare at her. The condor attacks her again (because the baby bird goes back to Heather) and Alejandro watches with worry. After Heather leaves Sierra and Cody to fly in the economy class, Alejandro stands up, knowing that Heather picked him to fly with her. She blushes, and tells him not to "get any ideas" and that it's "strictly strategic". Alejandro responds by saying that's what she always insists.
After Alejandro plots his next scheme, he is seen sitting next to Heather in first class as she wakes up. Once Alejandro thanks Heather for bringing him to first class with her, Heather tells him not to mistake it for her liking him and claims that it is all simply strategic, although Alejandro gives her a doubtful hum. For a majority of the episode, Alejandro makes Sierra go after Heather because of a fake picture he made of Cody and Heather sleeping together. After Cody tells Heather she brought Alejandro to first class because she likes him, Heather claims that it is all strategy, and states she does not like him questioning "Why does everyone keep saying that?". Once Sierra wins the first challenge, she uses the post-digger to attack Heather while Alejandro watches with a genuine look of fear and worry. During the second part of the challenge, Heather taunts Alejandro as he digs with his hands up to the point where he tells her to leave him alone, getting Heather to awkwardly leave and avoid his apparent rage.
Once Heather is stuck under a rock, she calls for help and Alejandro looks greatly concerned, despite having been previously irritated by her. Alejandro grins about Heather getting stuck and then Chris comes, stating that they must sing a song, This Is How We Will End It. During the song, Heather tells Alejandro that they're the strongest adversaries the game has ever seen, and questions if this is the kind of victory he wants, convincing him to pull her up. Alejandro helps Heather out of the ditch in his arms but makes Heather promise her to never vote him off and gets her to finish the challenge together. He holds for her a while until she requests a second time to be put down, and he puts his hand on her shoulder explaining the plan to her. In the confessional, Heather states that "Whoever asked her that she liked his hand on her shoulder will be wedged into a hole of their own." In Alejandro's confessional, he says that his feelings did not get in the way, but it was all strategic, albeit sounding a little doubtful. After Sierra blows up the plane, Alejandro is seen covering Heather with his own body seemingly to protect her from any falling debris. Once everyone comforts Sierra, Heather runs off to burn the remaining votes because she regrets voting for Alejandro (she only did so after learning from Sierra that Alejandro plotted against her). Her hasty retreat to the bonfire makes Alejandro suspicious, as he sneaks over to the fire almost instantly after Heather leaves and manages to save the four passports before they completely burn. Upon seeing that Heather had voted for him, Alejandro declares, "You will regret this Heather... oh yes, you will regret this," in a vengeful and hurt tone.
As Chris is doing the intro to the episode, he recaps how "Alejandro felt a tremor in his little black heart," showing that Alejandro's attraction towards Heather played into how he played the game. In the beginning of the episode, when Chris is still shocked about the plane blown to bits, Heather and Alejandro exchange worried stares as if they felt sympathy for Chris and his loss, although they were really wondering if they could have just moved on and returned to the game, which Alejandro eventually vocalizes, and Heather fully agrees to. After Sierra follows Cody to help look for scrap to get to Hawaii, Heather hints to Alejandro her interest, and willingness, to join him in an alliance, to which Alejandro only gives her a menacing glare before responding, "Why would I do that?" Heather claims that they agreed to become the final two, hinting back to their "fake alliance" in African Lying Safari. However, Alejandro keeps his glare at her and tells her that he "knows what she did." Trying to get off the topic, Heather claims that she's done a lot of things though her answer is clear when he shows her the burnt passport of her vote against him. Alejandro chides Heather about her obviously broken promise in Awwwwww, Drumheller, while Heather only smiles innocently. Storming off, Alejandro bids Heather farewell, hoping she does not make it to the final two, to which Heather replies "Oh, like you wouldn't do the same!" In the confessional, Alejandro admits that "Heather has a way to make his focus slip, like a too small speedo" before he lists off the things about Heather that distracts him like "her clever words, or her distrustful eyes... or the way she tucks her hair behind those cute little earlobes...", but he catches his slip-up and slaps himself, telling himself to "focus."
Storming out of the confessional, Alejandro keeps slapping and telling himself to "focus," which leads to yet another dispute between him and Heather over the walkie-talkies about how Heather is good at turning people off. After their angry exchange, Heather claims that without "Evil-jandro" distracting her, she will be able to focus on the game much more clearly. When Alejandro is in the luggage car of the train, he vows to find Heather and crush her like she crushed his heart. He finds her shortly after and unleashes a feral Ezekiel (whom he discovered in the luggage car) on her. They glare at each other angrily when Alejandro arrives at the train with Ezekiel after being told by the train conductor to show him the tickets. Soon after, however, Ezekiel vanishes and Heather and Alejandro start fighting each other. They end up on top of the train car and constantly try to push each other off the train. He manages to throw Heather off the car, but she grabs on and climbs underneath it. She jumps back on, and they fight again. Eventually, once they end up on opposite cars, Alejandro uses his belt to disconnect the coupling between the cars and sends Heather's car rolling off. As she rolls off, he says, "I think I'll miss your legs most of all," only for Heather to jump over and kick him with those same legs. In the song I'm Gonna Make It, Heather and Alejandro are dancing together, but say that they hate each other. Alejandro brings up again how voting for him "wasn't right," and Heather orders him to stop trying to make her feel guilty, as he would have done the same. Later, Heather lands on top of Alejandro suggestively in Tijuana Beach.
Knowing that Alejandro is greatly hated by the contestants, Heather tricks Cody into losing to Alejandro, hoping Cody's supporters will move to her side and vote for her instead. However, it turns out the winner will not be crowned by votes. As Heather and Alejandro compete against each other in the final two, they taunt each other and hope the other one loses. During the song Versus, they insult each other many times. At a checkpoint of the challenge, Heather mockingly calls Alejandro "José," causing Alejandro to snap and inform her about his past with his unkind brother, coincidentally named José.The final two then make it to the top of the volcano where Heather arrives right after him, crying and claiming that she gives up. This distracts Alejandro right as he is about to throw his dummy into the lava. He turns to taunt Heather and urge her into admitting that she loves him, to which she accidentally confesses to, shocking several contestants. Alejandro then confesses his own feelings to Heather saying that flirting with her at first was strategic, but later fell for Heather and they share a slightly forced kiss (similar to a French kiss), disgusting almost everyone around them. Heather is surprised by it at first but enjoys it for a second. Immediately after this, Heather betrays him by kicking him in the groin, onto an ice cube, and slapping him away, causing him to slide all the way down the volcano on an ice cube. In Alejandro's ending, Heather accidentally throws Alejandro's dummy into the volcano and unintentionally gives him the win. In Heather's ending, Heather throws the correct dummy and she is declared the winner of the season. Either way, her actions indirectly lead to Alejandro becoming crippled and charred, when he is run over by the fleeing cast and burned by the volcano's lava later on.
When the entire old cast appears on a yacht, Alejandro and Heather are at the bow together, with Alejandro (still in the Drama Machine) holding Heather in his arms. Heather looks at him in a confused and annoyed manner, which indicates that Heather is oblivious to the robot's true identity.
When Lindsay taunts Heather about missing her "honey bunny", she shoves her aside saying she is glad that "handsome jerk" isn't back, not realizing that he is right there, still in the Drama Machine. When Alejandro is placed on the Villainous Vultures next to Heather, he tries to get close to her, but she rejects him immediately. He tries to talk to her while they and the rest of the contestants were walking down to the beach, but she asked for him to keep away, unaware of his identity. In the confessional, she shudders, saying there's something about the robot that she doesn't like. When Alejandro is accidentally pushed down into the shark infested water by Lightning and Scott, Heather is happy that the robot would get eaten. However, Alejandro finally breaks free of the Drama Machine by getting the key for the challenge, which causes Heather and the other contestants to be in shock.
As Alejandro is getting a massage, Heather scolds him for hogging the masseuse, only for Alejandro to complain about his injuries and how Heather never bothered to text him back over the last year. Heather retaliates by saying that he never texted her first and gets distracted by Alejandro waxing his eyebrows. Alejandro calls eyebrow waxing as "man-scaping" and angrily replies that he couldn't text her back because was trapped in the robot suit for a year, causing Heather to rip off his eyebrow wax. During the confessional, Heather reveals that she thinks Alejandro is faking his injuries for sympathy and exclaims that she will not fall for "him." Realizing her slip up, she changes "him" to "it." In Alejandro's confessional, he confesses that he still has feelings for Heather, commenting on how radiant she is along with her "glassy locks, perma-frown, and the way her lip hair catches the sunlight." Throughout the challenge, Heather attempts to catch Alejandro faking his legs injuries. At one point, Heather seems to notice that Alejandro's legs moved but she realizes that they didn't, due to the fact that a crab came from up and under his legs. After watching the crab pinch Alejandro's foot, Heather mentions she feels "awful" for doubting his word about his legs falling asleep. However, in the confessional, Alejandro reveals that his legs have already recovered and that he pretended that they aren't in order to make Heather feel guilty.
Like Heather and Jo, Alejandro attempts to form an alliance with Heather's long time enemy, Gwen. He hopes by doing this, he will be the one that Heather needs, but he quickly corrects himself by saying Heather and Jo. Throughout the episode, Alejandro is often seen arguing with the two of them.
Alejandro nominated Heather for the position of team captain which she accepted reluctantly, ordering he do the challenge first, which he happily accepts. He later offers to switch places with her after she complains about Sam's switch with Zoey. While Alejandro is competing, Heather threatens him with elimination if they lose, which the team seemingly did. At the elimination ceremony, both seemed to plan to vote the other for elimination but were spared as Sam had cheated during the challenge meaning the Villainous Vultures were the real winners.
At the beginning of the episode, the two of them are seen eating dinner at the hotel. Heather becomes irritated with Alejandro who keeps on whistling while eating but Alejandro simply ignores her, calling her typical. In the confessional, Heather is surprised with Alejandro's comeback, believing that he is losing interest in her. During the challenge, Heather pretends to be under the effects of the Blue Harvest Moon, becoming a much nicer and more cheerful person, as opposed to her cruel self. Throughout the challenge, Alejandro is taken aback by Heather's sudden change of behavior. While crossing the bridge, Alejandro manages to catch her when she almost falls off. Her immediate reply is "I knew you still cared." In the confessional, Heather reveals that she was only pretending to be affected by the moon in order to play with Alejandro's mind. He is mad in the confessional at her trickery. After the moon becomes normal, Heather "changes" back into her usual self, even insulting Alejandro by calling him "Blahlejandro". However Alejandro is relieved by the return of her usual mean self.
After seeing Gwen and Cameron form a bond, Heather quickly asks Alejandro to form a temporary alliance with her. Alejandro complies by kissing her hand which disgusts her. Their subsequent confessionals however, reveal that they are trying to lower the other's guard so that they can vote for the other. During the challenge, Alejandro finds an egg but Heather quickly steals it from him, angering him. Heather later convinces the other members to vote for Alejandro by lying that he is targeting either Scott or Cameron.
Heather eventually finds the McLean-Brand Chris Head and hides it behind some rocks. Unbeknownst to her, Alejandro sees this and steals the idol. Their team lose the challenge and they vote for each other that night. As Alejandro votes Heather, he calls her beautiful. Just as Heather planned, Alejandro receives the most votes and she celebrates his defeat. However, Alejandro reveals to her that not only his legs have already recovered, but also he has the idol, meaning he is immune, much to Heather's chagrin. Thus, Heather who receives the second most votes, is eliminated instead. Right before she took the Flush of Shame, Alejandro admits that he betrayed her to "avenge the shame she caused him" two seasons ago, but then flirts with her, claiming that her "slate is clean" and offers to renew their relationship as an official couple. Heather however, quickly shoves him off the toilet in response, wanting to leave.
When Gwen and Courtney wish that Alejandro will have to fight Heather, he says that there is only one person he prefers to fight less than Heather, his older brother, José, who Alejandro is pitted against. When his arrogant brother talks negatively about Heather, dubbing her personality "unattractive," Alejandro growls furiously. This motivates him to beat up José to avenge Heather. As Alejandro delivers his final blow, he proclaims that it is for calling "any aspect of Heather unattractive." He wins the round for Villainous Vultures, and in his confessional, asks Heather to call him.
In the exclusive clip, Alejandro and Heather are reunited at the Yukon, after the former takes the Flush of Shame. Although still bitter at her elimination, the two of them reconcile after Alejandro tells her that she misses her, before they leave on a snowmobile together.
Both Alejandro and Heather are selected by Mal to be his helpers for the final challenge. Much to Chris's surprise and disgusts, the two of them reveal that they had officially begun a romantic relationship following their eliminations. Throughout the episode, they spend more time making out rather than helping Mal to progress. At one point while using the confessional together, they elaborate that the money was getting in the way of their happiness and without anything holding them back, they can finally be together. Eventually, their constant making out, coupled with Mike and Zoey's reunion and Gwen giving Cameron a friendly kiss on the cheek, gets on Chris's nerves and he declares that anyone is eligible to win the million dollars.
