Heather develops an attraction towards Alejandro during the beginning of Total Drama World Tour, and as the season continues, Alejandro begins to reciprocate these 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. He often compliments and flirts with her, noticeably more than he does with other female contestants, to which Heather often responds with disgust.
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. Both made 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 for fame and fortune and countless amounts of betrayals she had performed) betrayed him by kneeing him in the groin and (depending on the ending) tossing him off of the volcano in order to win the season and the prize.
Prior to Total Drama All-Stars, Heather reveals that her relationship with Alejandro is over. The two of them are placed on the same team, where they continue arguing. Despite this, both Alejandro and Heather are shown to still harbor feelings for each other, although they both continue to deny it. By the sixth episode, they both try to eliminate each other. Heather convinced everyone to vote for Alejandro, but he stole her idol and eliminated her. They finally become a couple in The Final Wreck-ening, making out and mostly resolving their differences.
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, and she glares at him in response.
In the confessional, Heather states that she could see right through Alejandro and his "tactics" and that states that he looks like a threat to her. She also becomes embarrassed in the cockpit confessional when Chef rambled 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"; whether she intentionally or unintentionally forgot his name is unknown.
Heather seems to be falling for Alejandro during the episode, as seen by her confessional comments. An example was when she called him "perfect," which she regretted saying after asking herself what Alejandro's deal is, before grunting out of aggravation. Alejandro also blew a kiss at Heather, in response to her sticking her tongue out at him after successfully taking Sierra from his team for Izzy. Heather seemed to be somewhat shocked and slightly flattered by this, but quickly got a hold of herself and ignored 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.
After blocking his attempt at bribing Sierra with snacks from first-class, Alejandro admits in the confessional that Heather is "good" as he realizes her plan to align with Sierra, Chris' "pet," at the time. When the boats belonging to Team Chris Is Really Really Really Really Hot and Team Victory fly out of the sewer pipe and land in Central Park, Alejandro realizes that Team Amazon is still missing and with a genuine look of fear and concern on his face, he worriedly asks where Heather's boat is.
Moments after, Heather and the rest of Team Amazon emerge from the same pipe. Later in the challenge, after Heather realizes that Alejandro has been messing with Sierra's head, she switches Alejandro's baby carriage that contains Noah in it with an actual baby carriage containing a real baby. 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 was a good one. However, once it is announced that the challenge is a reward challenge, Heather becomes angry, and even more so when Alejandro blows a kiss to her.
Leshawna accuses Heather of being jealous because Alejandro is paying more attention to her, 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. When Leshawna beats Heather up towards the end of the second challenge, Alejandro is very 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.
There was not much interaction between the two until the end of the episode, when Team Amazon was at their very first elimination ceremony. Alejandro sneaked up to Heather, who was sitting at the very end of the bleachers and away from the others, and tried to cheer her up with fake sympathy, stating that the game would be so much easier for him after her departure. Heather, unfazed by the insult, revealed that she knew that Alejandro manipulated Leshawna, and possibly Bridgette. She then threatened him, stating that he was lucky that he didn't attempt to fool her. Alejandro then smugly replied by telling her that, with the temptation of a kiss, even she couldn't resist him forever. Both parties leaned closer to each other, and Heather angrily told Alejandro that she would have crushed him. Alejandro was taken aback by Heather's comment, but before he could speak further, Chris began the ceremony and Alejandro vanished. Later, after Heather was saved from elimination, due to the challenge being a non-elimination, she stated in the confessional that, after making her teammates pay for their attempt to vote her off, she would 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, points at Sierra, who is on the floor sobbing over Cody's vote 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 stated that if she didn't know better, she would have thought that Heather had a crush on Alejandro. Both she and Gwen made fun of Heather by stating that she was "in love," and Heather insisted that she wasn't. Afterwards, Heather was lurking around in the vents to gather information and see if Alejandro's team was trying to make an alliance with DJ, who was the only remaining member on his team. After hearing of DJ's plans to lose the next challenge, she accidentally fell out of her hiding spot, and Alejandro teased her by asking if she was spying on them. Heather denied the accusation and covered it up by stating that she had merely dropped her pen, and that she was "just scribbling."
Later on, Heather gave DJ a cushion from first-class that she had carried out of the plane so he wouldn't drown, and asked him for an alliance afterward. Alejandro was shocked, and asked Heather why she was asking him now. Heather replied by calling him jealous, but Alejandro merely said that she would have asked for an alliance before giving him the cushion, as a form of bribery. Heather realized her mistake, and in the confessional, stated that Alejandro was "good" and let out a romantic sigh. However, she quickly noticed what she had done and demanded that she got the tape back, not wanting her feelings for Alejandro to be seen. After Heather did not object to Courtney's plan, Gwen stated in the confessional that Heather shouldn't let her "obvious crush" on Alejandro get in the way of the game. Then, when Heather got DJ to the second part of the challenge before anyone else, Alejandro complimented her, calling her "ambitious one." When Alejandro learned Heather put Owen's socks in the clam chowder his team won, he is 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 complained about Alejandro, and how he was probably making DJ feel welcome in first class, calling him a jerk. During the challenge, right before Heather took a dive into the water, Alejandro complimented her perfect diving form. This caused Heather to lose focus and land hard on the water. He apologized in a teasing tone, and she growled back at him as her body sank into the water. When Alejandro saved Gwen from the eels and took the gold from her, Heather ran up to him and snatched 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 stated that he deserved it, smiling. Heather later on smirked at Alejandro and asked him how it felt to be "toast" when his team was behind in the "Bobsled of Death" challenge. Alejandro retorted by stating that he didn't know, as he hadn't been "toasted" yet.
At the beginning of the episode, Heather noticed that Alejandro was missing when she and the rest of the cast was on the double-decker bus. After Chris announced he was caught by Jack the Ripper, Heather asked Courtney and Gwen if they thought he was okay, showing concern over his disappearance. However, she quickly added that his absence would be good for the team, covering up what she had said earlier. She then asked if they should try and find him, but Gwen and Courtney just laughed the idea off. At the end of the episode, when Chris announced that Team Chris Is Really Really Really Really Hot was going to their first elimination ceremony, Alejandro and Heather were seen smiling at each other.
After Chris left the common area, announcing that they were going to Greece, and re-creating the Olympics, Alejandro and Heather began to taunt each other about their teams' superiority. When Heather slapped her forehead after Sierra attacked Courtney, Alejandro began to mock Heather's team. Later on in the episode, Chris stated that because Alejandro and Heather had not yet competed, they had to compete against each other in a hurdles race. Heather shot Alejandro a smug smile and bragged about how she was very flexible. To her surprise, Alejandro proved to be more flexible than her by splitting his legs apart while tying his hair in a ponytail with his feet. As they competed, Alejandro taunted Heather and showed off during the race while she looked at him in annoyance. Eventually, Alejandro lost concentration and crashed into a hurdle, which cost him the race and Heather cheered herself on for being victorious over Alejandro in the race.
In the economy class section, Alejandro began to talk to his remaining teammates: Duncan and Owen, about how Team Amazon was only powerful because they had both Courtney and Heather. He began to scheme ways to break them apart, causing Owen to suggest that Alejandro should act as if he was crushing on Heather and then eliminate her; similar to how he did with Bridgette and Leshawna. Moments later, Duncan suggested flirting with Courtney so Heather would get jealous, knowing that Heather was "into" Alejandro. Later on, Heather started to get annoyed by Alejandro when he flirted with Courtney, but she figured out his plan and attempted to flirt with Duncan as a way of getting back at him. Courtney later asked Heather if there was anything going on between Alejandro and her, resulting in Heather quickly denying the suggestion, regardless of the fact that she was visibly upset with Alejandro flirting with Courtney. Even later on, Alejandro was shown to be perplexed in the confessional, when he witnessed Heather flirting with Duncan. He began to worry, stating that Heather had never used flirtation before, but then assured himself that she wasn't really in love with Duncan, adding that she did not have "true passion" in her eyes when doing so, although he did not seem entirely convinced by that. When Heather helped Duncan up and flirted with him again, Alejandro was visibly upset, as he gasped in surprise before quickly turning his head the other way, in order to focus less on Duncan and Heather, and more on the game, as well as 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 failed due to the fact he misses Gwen. She later stares in admiration at Alejandro after he removes his shirt during the challenge. 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' intercom announcement of the upcoming elimination ceremony interrupts them. Alejandro then makes a confessional explaining his "plans," accidentally revealing that he actually has feelings for Heather, so 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 they both smile at each other as they walk off. While Alejandro tries to give Heather directions to get to her wedding dress, Heather complains and eventually gets there. Once she does, she 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 were about to cross the tight rope, Alejandro calls Heather his "better half" and scoops Heather into his arms bridal style, with Heather sighing and showing a satisfying smile. Halfway across the rope, Heather and Alejandro fight about who to vote off next, and she causes them to fall and lose the challenge, though Alejandro later reveals that he fell on purpose as a strategic move, not wanting to appear too strong a player.Cody, debating over whether or not Sierra and Cody actually are 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." 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 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, then Heather angrily tells Chris to get rid of Blaineley.
Throughout the episode, they have a running gag of speaking at the same time. At the start the episode, after Alejandro notices Duncan's sudden happiness, Duncan says, "Speaking of failed romance..." and starts teasing Alejandro and Heather, suggesting that he should go in the common area so that the two can 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's 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, though the soccer ball 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 was ridiculous that he and Heather were speaking at the same time.
When Heather cracked open her gourd, Alejandro is seen smiling at her. 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 planned 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 it. Once in the elimination room, Chris grins at Alejandro and Heather while commenting, "tension-y." After Alejandro picks Cody to go into first-class with him, Heather complains about him breaking the "fake alliance" and growls that he's going down.
In the beginning of the episode, Alejandro plots against Heather by having Cody and himself vote her off the show. In Sierra's confessional, she calls Alejandro and Heather's attraction a "love fest" while adding that with just them in the final four, it feels like a "double date in a can." 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 Alejandros 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, and 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," then Alejandro says that's what she always insists. Then it cuts to Sierra in the confessional, who says excitedly "Holy double date in a can," referring to her previous confessional about Heather and Alejandro.
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 mistaken it for her liking him and claims that it is all simply strategic, although Alejandro gives her a doubtful hum. Half 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 was all strategic 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. Alejandro grins about Heather getting stuck and then Chris comes, stating that they must sing a song, This Is How We Will End It. After Alejandro helps Heather out of the ditch in his arms, he 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 in a hole." Then Alejandro's confessional comes up as he goes on saying 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 comforted 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). But Alejandro sneaks over to the fire almost instantly after Heather leaves and manages to save the four passports before they completely burn. He sees that Heather voted for him and states, "You will regret this Heather... oh yes, you will regret this," in a vengeful and hurt tone.
As Geoff and Bridgette review the final three, Bridgette states that other than her "heinous attitude" as one of her biggest weaknesses, Heather's other biggest weakness is Alejandro. Geoff agrees, along with adding that in order to win, she will "have to find a way to block him out."
As Chris was 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 yells at Heather with wide eyes about her obviously broken promise, formed one episode prior 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. 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. 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 saying 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. Cody, one of Heather's helpers, notices this and uses it to Heather's advantage.The final two then makes 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 was 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, disgusting everyone in the peanut gallery except for Owen, Sadie and DJ. 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, and slapping him away, causing him to slide all the way down the volcano on an ice cube. In Alejandro's ending, Heather, however accidentally threw Alejandro's dummy into the volcano. In Heather's ending, Heather threw the correct dummy and she was declared the winner of the season.
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 noticeably has a annoyed look on her face as she looks at him, this indicates that Heather is oblivious to the robot's true identity.
When Lindsay taunted Heather about missing Alejandro, she shoved her aside saying she was glad that "handsome jerk" wasn't back, not realizing that he was right there, still in the Drama Machine. When Alejandro was 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 still said no. After Alejandro was accidentally pushed down into the shark infested water by Lightning and Scott, Heather was happy that the robot would get eaten. However, Alejandro would finally break free of the Drama Machine by getting the key for the challenge, which causes Heather and the other contestants to be in shock.. 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, permafrown 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 seemed to notice that Alejandro's legs moved but she realized 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 excitedly. He later offered to switch places with her after she complained about Sam's switch with Zoey. While Alejandro was competing, Heather threatened him with elimination if they lost, which the team seemingly did. At the elimination ceremony, both nominated the other for elimination, but were spared as Sam had cheated during the challenge meaning the Villainous Vultures were the real winners.
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, revealed that they are trying to lower the other's guard so that they can vote for the other. During the challenge, Alejandro found an egg but Heather quickly stole it from him. Heather later convinces the other members to vote for Alejandro by lying that he is targeting either Scott or Cameron.
Heather eventually found the McLean-Brand Chris Head and hid it behind some rocks. Unbeknownst to her, Alejandro saw this and stole the idol. Their team lost the challenge and they voted for each other that night. 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 has recieves the second most vote, was 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.
Alejandro is pitted in the boxing match against his older brother, José. When his arrogant brother talks negatively about Heather, dubbing her personality "unattractive," Alejandro grows furious. This motivates him to beat up José to avenge Heather. As Alejandro delivers his final blow, he proclaims that it was for calling "any aspect of Heather unattractive." He wins the round for Villainous Vultures, and in his confessional, asks Heather to call him.
Alejandro and Heather were shot out of the balloons by Mal and became his helpers in The Final Wreck-ening. They both did not care about being Mal's helper since they revealed they have been dating ever since after their eliminations, which shocks Chris. As Mal was about to throw Heather into the toxic river to "cross over," Alejandro immediately disrupts him with an idea to cross the acid river: pole vaulting. However, when Mal crosses over, they both ask him how they are going to cross over. He replied, "I'm not here to help you! YOU'RE here to help me!" This gets both of them angry. They are later seen crossing the toxic river on a log boat. When they arrive on Level 3, Alejandro and Heather see Mike and Zoey kiss which makes them kiss.
Chris gets disgusted and proclaims that this show is meant for pain, not "hugs and kisses." When Chris announces that anyone can win, Alejandro and Heather nearly maul each other trying to reach the top to win. The now controlled Mike drops Fang's fang into Alejandro's hand, making Fang angry, and chasing him. Heather is hit with a stick by Gwen. They arrive at the top to see Mike win, and hug each other in fear when they realize the island is sinking. They are last seen being chased by Fang.

- Both have eliminated Harold, Bridgette, DJ, Duncan, and Cody in the seasons that they were an antagonist. However, while Alejandro eliminated them directly, all of them were eliminated by Heather indirectly.
- Both are responsible for the highest amounts of eliminations out of any other contestant in the series (whether indirectly or directly):
- Heather caused seventeen (eighteen if her ending of Hawaiian Punch counts).
- Alejandro caused thirteen.
- This is the only couple in which both have had their ethnicity confirmed:
- Alejandro is Hispanic.
- Heather is Asian.
- This is the first final two:
- Both had multiple contestants fall for them.
- This couple bears many similarities with Rob and Amber from Survivors: All-Stars, as both are the first couples from their respective series to reach the final two together. Originally from different teams, they will align with each other after the merge to eliminate the rest of the contestants to reach the finals. Both couples also share their first kiss in the finals. Interestingly, both male contestants have less supporters than the female.
- They were the first members on their respective teams.
- This couple is one of the six couples that is currently together. The others are Beth and Brady, Bridgette and Geoff, Dakota and Sam, Lindsay and Tyler, and Mike and Zoey.
