This article focuses on the interactions between everyone and Harold.
Harold is a social out-class among the contestants. His outward appearance, plus his somewhat unhygienic behavior had the others label him as weird, among other names. In addition, he usually annoys them by telling them random facts they are not interested in. During challenges, Harold often tries to prove that he can be a valuable asset to his team, though he normally ends up embarrassing himself or cause the opposing team has his lead. This leads to many contestants (notably Duncan and Courtney) to either pick on him or look down on him. Despite this, Harold never shows any real hatred for his fellow contestants and earns their respect when he did manage to help his team to win many times throughout the series. This, combined with his loyalty and niceness, has made him fairly likable.
Harold is the first person to be eliminated due to Alejandro's manipulation. In Super Happy Crazy Fun Time Japan, Alejandro gives a pep talk to Harold before the challenge starts, causing him to become overconfident. After Team Victory loses, Alejandro convinces him to quit the competition in order to maintain his honor, also adding that Leshawna will surely be impressed by his decision. Harold blindly follows his instructions and takes the Drop of Shame later that day despite DJ receiving the most votes.
Eventually, Harold comes to realize Alejandro's treachery and begins to hate him. In Aftermath: Revenge of the Telethon, Harold and Bridgette join Leshawna in singing Sisters to express their hatred for Alejandro. In Hawaiian Style, Harold raises his hand when Bridgette asks who was eliminated due to Alejandro's manipulation. Like the majority of the cast, Harold chose to support Cody over Heather or Alejandro. In Hawaiian Punch, after Cody lost the tie-breaker challenge, Harold joins him in helping Heather beat Alejandro in the finale, even badmouthing him during Versus, forcing Alejandro to hurl a lightning bolt at him. In Heather's ending, Harold is one of the many contestants seen cheering when she beats Alejandro, and once Alejandro loses, Harold and the others (except Courtney) cheer for his defeat.
Beth and Harold are placed on opposing teams in Total Drama Island and have very little interaction with each other until after the merge in Total Drama Action. They develop a friendship at this point until one point, when Beth starts to believe that Harold has feelings for her. After much consideration, Beth willingly ends her relationship with Brady to give Harold a chance. After Harold is eliminated, Beth tells him that she will wait for him, much to his dismay. Harold is well aware of Beth's attraction towards him but he has no interest to start a relationship with her, claiming that he doesn't want to disappoint the other girls who he believes are attracted to him. In the exclusive clip, Harold states that he would be able to brag to his classmates that he had a girlfriend. However, he hesitates on whether he should tell them it was Beth
In Aftermath: Bridgette Over Troubled Water, Blaineley is annoyed when Geoff chooses Harold as the first guest as she wanted to bring in Bridgette in order to humiliate her in front of of Geoff for cheating on him with Alejandro. After getting pushed onto Blaineley's lap by Geoff, Blaineley roughly pulls Harold up by the hair. She shows a short tribute video of Harold which only lasts a few seconds. Feeling under appreciated for a contestant who participated in three seasons, Harold demands a better recap of him, prompting Blaineley to reveal a video of him getting beaten up by the contestants several times during Total Drama Island for spouting out unnecessary information. Blaineley even brings up Harold's feelings for Leshawna and forces him to sing a song with the Drama Brothers though Harold doesn't seem to mind.
Bridgette appears to be the most sympathetic towards Harold out of all of his teammates in Total Drama Island. While she sometimes finds Harold odd and questions his behavior, she is usually patient with him even when he messes things up. She also does not approve of Harold getting bullied by others, and does not join in the rest of the Killer Bass to not make fun of him whenever he gets injured or humiliated. Likewise, Harold will gives support to Bridgette during troubling times, and has helped her out when in some tough challenges.
In Not So Happy Campers - Part 1, Harold is almost hit by Bridgette's surfboard twice and tells her to watch it. After Harold accidentally makes a sensitive remark to Leshawna, Bridgette and DJ restrain Leshawna from attacking Harold. In Not So Happy Campers - Part 2, Bridgette accidentally hits Harold with a plank twice while building their team's hot tub.
In Dodgebrawl, Bridgette gives Harold some water after Courtney requests a time-out from Chef during the final round of the dodgeball game. She, along with the rest of the team, chants Harold's name when he faces-off with Owen. In Not Quite Famous, Courtney and Bridgette reluctantly choose Harold to compete in the talent contest since the remaining contestants either has poor talents or unavailable. Harold surprisingly manages to score enough points for the Killer Bass to defeat the Gophers for the second consecutive episode. This amazes Courtney and Bridgette and they hug him affectionately. In Up the Creek, Bridgette scolds Harold for using all their team's oars as firewood, leaving them stranded on Boney Island.
In Paintball Deer Hunter, Bridgette is reluctant to be her team's hunter even though Harold reminded her that that the game is "all pretend" and that they weren't really killing anything. Though unconvinced at first, he reminds her that Heather is one of the "deer" and this persuades Bridgette to compete in the challenge due to her dislike of Heather. After successfully shooting Heather, the two give each other high-fives. In Who Can You Trust?, Bridgette and Harold are assigned to the Blind Trapeze Challenge. Bridgette is terrified at first, but Harold tells her to trust him. Bridgette nods and jumps as Harold catches her, avoiding the stinging jellyfish in the pond below, resulting in their team winning the challenge.
The two are on the same team again in Total Drama World Tour though their time together was short as Harold is eliminated rather early with Bridgette following him an episode later. During their short period together, Bridgette finds Harold bossy when he takes charge of their team and presumably voted for him after their team's loss.
In Not So Happy Campers - Part 1, Chef angrily yells at Harold when he begins to complain about him getting hypoglycemic if he did not get enough sugar. In Not Quite Famous, Harold's beat-boxing performance impress Chef enough to give the Killer Bass enough points to win the challenge. In X-Treme Torture, Chef was shocked to find out that Harold is the person who send the poems to Leshawna, not thinking that someone like Harold can be romantic or be a good poet. Chef reveals that he had read Harold's poems and states that the comments are "spicy."
In Masters of Disasters, Chef caught the cast complaining about his dish. Harold notices him and tries to compliment his cooking by stating that it is "too complex for their taste buds," to everyone's agreement. Chef knows they are lying and says "I hate stuck ups." In 2008: A Space Owen, Chef throws Harold into the Lame-o-sine after he is eliminated before Harold could reveal the true purpose of Owen's return to the other cast mates.
In Aftermath: Bridgette Over Troubled Water, during Harold's recap, Chef is in line with several other characters ready to beat Harold up, as he annoys them with his explanation of the square of "111,111,111" being a palindrome.
Like everyone else, Harold hates Chris's treatment towards the contestants while Chris dislikes Harold's geeky nature as well as interrupting him with his annoying facts while he is trying to explain the challenge. When Harold first arrives at the island, Chris is visibly disturbed by Harold's odd behavior. In Paintball Deer Hunter, Chris shoots Harold with a paintball gun to demonstrate the challenge to the other campers.
In Masters of Disasters, Chris is glad that Harold managed to save the others just in time or else he would have been sued if the contestants had died. In Ocean's Eight - Or Nine, after the Gaffers find out that the money they received from the first part of the challenge was "non-negotiable Chris cash" that couldn't be used, Harold admits that he dislikes Chris's smile while staring at one of the fake bills with Chris's face on it. In Million Dollar Babies, Chris pits Harold against Lindsay for the boxing challenge as they did not do well during the training course. Despite Lindsay successfully knocking out Harold, Chris deemed Harold the winner of the challenge as he gained extra points for performing excellent slow motions. During the Awards Ceremony, Chris tells Harold that he is the only member of his team that is safe. As Harold is about to speak, Chris shuts him up and quickly gives him his Gilded Chris.
In Super Hero-ld, Chris is impressed with Harold's "Captain Alberta" costume and give him 7/10 in addition for "keeping it Canadian." After Leshawna is eliminated later that night, Chris shoves Harold aside to close the episode, breaking Harold's glasses in the process. In Rock n' Rule, Harold starts crying after Duncan calls him by his middle name, Doris, and ran into Chris's arms, breaking all the card board cut-outs in the process. Chris then gives him a comforting hug as Harold continues crying. In Crouching Courtney, Hidden Owen, Chris compliments Duncan's training strategy of making Harold clean all his cars.
In Walk Like An Egyptian - Part 1, Chris is noticeably annoyed by Harold who kept telling him how to say numbers in Egyptian. In Super Happy Crazy Fun Time Japan, Harold kept high lighting the cultural mistakes Chris made between Chinese and Japanese. Annoyed, Chris tells Chef to cut the plane door open, sending all the contestants out of the plane. Later, Chris is annoyed when Tyler and Harold begin talking while he is explaining the challenge and stops the conversation by hitting his "geek gong". In Hawaiian Punch, Harold and the rest of the contestants laugh at Chris and Chef as their boat begins to sink after Ezekiel crashes into it.
In a clip shown by Blaineley in Aftermath: Bridgette Over Troubled Water, Cody is one of the people lined up to beat Harold up, after he is annoying everyone by explaining a mathematical phenomena. In Hawaiian Style, like the majority of the contestants, Harold chooses to side with Cody in the finale as he is the "least evil" among the final three, and is one of his biggest supporters. Harold goes to great lengths to show his loyalty, by interrupting Who You Gonna Root For? to rap about Cody, as well as representing him for the challenge. Harold also picks a deer for Cody's "spirit animal", due to his "large innocent eyes and tiny tail." In Hawaiian Punch, Harold continues to show his support for Cody by telling him to hit Alejandro in the kiwis. After Cody loses, Harold supports his decision to help Heather and joins him.
Courtney greatly dislikes Harold due to his weird habits, and believes that Harold isn't a useful teammate despite Harold managing to help their team win several times. However, the real conflict eventually arises after Harold rigs the votes and causes Courtney to be eliminated in Basic Straining in order to get back at Duncan. After Courtney finds out about this, she vows revenge on Harold. Additionally, Harold's actions has also caused Duncan to further torment Harold throughout Total Drama Action. Their conflict intensifies after Courtney's return and begins to treat her fellow contestants poorly. After the merge, Harold teams up with Beth and Lindsay (who are also victims of Courtney's wrath) in order to get rid of Courtney. The conflict continues in the last few episodes of Total Drama World Tour as the two compete to make sure the finalist they support wins.
DJ and Harold have been close throughout Total Drama, being on the same team in all three seasons they participated together. Though at times, DJ helps Duncan and Geoff to bully Harold, Harold does not hold a grudge against him or Geoff. In fact, DJ is the first of the group to stop making fun of Harold. As the series progresses, the two of them grow to respect each other. Despite being on the same team in Total Drama World Tour, they had very limited interactions due to Harold's early elimination. It is notable that Harold actually saves DJ from elimination by quitting the competition, as it was DJ who received the most votes that episode.
Harold's conflict with Duncan dates back to the first episode of the series. Throughout Total Drama Island, Duncan frequently picks on Harold by pulling several pranks on him. Harold will eventually retaliate by rigging the votes in Basic Straining and causing Courtney's elimination. Duncan eventually finds out about this and their conflict becomes even more intense in Total Drama Action. Being the final male members of their team, however, the two of them are often paired with each other during challenges and are able to lead their team to victory. Eventually, Duncan and Harold try to end their conflict but due to Owen's interference, this fails and their conflict continues.
Harold is shown to be very worried when Eva rages due to losing her MP3 Player in The Big Sleep and narrowly dodges a book thrown by her. Because of her temper, Harold most likely voted for her that night with the rest of the team.
Harold apparently didn't get along well with Ezekiel. In Haute Camp-ture, Ezekiel asks Trent why is he still helping Harold after what he did to Courtney in Basic Straining. In Walk Like An Egyptian - Part 2, Harold glares at Ezekiel for messing up Lovin' Time, forcing everyone to sing another song while they are paddling the Nile River. After Ezekiel loses their team's stick, Harold glares at him for making their team lose in what was supposed to be a non-elimination challenge. At the elimination ceremony, Harold angrily stamps Ezekiel's passport several times.
Throughout Total Drama Island, Geoff and Harold have a mixed relationship. Geoff will at times helping Duncan to bully Harold. However, there are a number of occasions Geoff has showed kindness towards Harold, with the latter appreciating this. Harold also doesn't seem to hold a grudge towards Geoff like he does with Duncan.
In Dodgebrawl, Geoff allows Harold to participate the final round of the dodgeball match, after being forced to sit out since the first round by Courtney. Throughout If You Can't Take The Heat..., Geoff, DJ and Duncan decide to teach Harold a lesson so that he does not keep his clothes lying around by stealing all his clothes, leaving him nothing to wear except his pajamas. They finally carry his bed to the Dock of Shame while he is asleep, leaving him naked in front of the girls when he wakes up the next morning. Forced to admit defeat, Harold promises not to leave his underwear lying around anymore. In Basic Straining, Geoff and Duncan would again pull several pranks on Harold.
During Total Drama World Tour, Harold is one of the most active members of the Peanut Gallery, and often helps Geoff out or annoys him with unnecessary facts. In Aftermath: Bridgette Over Troubled Water, Geoff brings Harold out as the first guest, in order to postpone having to meet Bridgette, after an incident. In Aftermath: Revenge of the Telethon, Geoff praises Harold for being the first to get some donations, even if he extorted it from his mother. In Aftermath Aftermayhem, Harold and the rest of The Drama Brothers help Geoff to humiliate Blaineley by performing Her Real Name Isn't Blaineley. In Hawaiian Style, Geoff is annoyed when Harold and Courtney interrupt him and Bridgette while they are singing Who You Gonna Root For?
Like most of the contestants, Gwen dislikes Harold for his geekiness but does not show hatred towards him. In The Big Sleep, during the morning exercise, Harold and Gwen are walking side-by-side, although Gwen tells him not to walk next to her. In the finale of Total Drama Island, while voicing out her opinions on the other campers, Gwen describes Harold "really weird." Harold is among those who supported Owen from the beginning.
In Total Drama Action, Gwen chose Harold to be the final member of her team. Though Harold believes that she chose him because of his "mad skills" and knowledge in filmography, Gwen simply wants to him to be quiet, and also because there are no other male contestants left. Harold somewhat plays a role in Gwen and Trent's break up as he supports Duncan's theory that Trent's obsession with the number 9 has something do with their relationship.
In The Chefshank Redemption, Gwen uses her team's shovel to whack Harold on the head in order to slow her team down and give the Killer Grips a winning chance. Ironically, Harold is not mad about this but develops an attraction to her instead. Despite this, Harold votes for her later that night.
After Total Drama Island ends and her true nature is revealed, Heather finds herself without an ally due to nobody trusting her, but found an unlikely friend in Harold who shows sympathy for her. Even after Heather betrays him in the special, Harold bares no hard feelings and continues to help her later on in the episode. After a brief talk, Heather agrees to be friends with Harold, although she looks at the camera and shakes her head, signifying she had no intentions to do so.
In Total Drama Action, Heather and Harold are placed on the team though they spend more time fighting with each other, often with Heather joining Duncan in mocking Harold's geekiness. However, there are moments the two of them get along well.
They did not interact much in Total Drama World Tour due to Harold's early elimination. However, during the finale, Harold decides to help Heather beat Alejandro due to his greater dislike for the latter. When she wins in her ending, Harold and a majority of the contestants cheer for her.
In Alien Resurr-eggtion, Izzy claims she has been abducted several times and has a tracking device in her neck. Harold looks at her neck and asks if it hurts, to which Izzy says only when she hiccups. In One Flu Over the Cuckoos, when the contestants realize the sickness is a fraud, Izzy assures Harold that his symptoms are the result of his paranoia inducing a placebo effect and he isn't sick at all. In The Sand Witch Project, Harold appears to be jealous of Izzy after seeing her superior card shuffling skills.
Justin and Harold do not interact much in Total Drama Island due to them being on different teams as well as Justin's early elimination. In Total Drama Action, they get along well despite being on different teams again. In The Sand Witch Project, Justin realizes Harold has a runny nose and advises him to visit a doctor. In Super Hero-ld, Harold and Duncan agree to form a new Guy's alliance with Justin as the girls outnumbered the boys at the time.
In The Princess Pride, Justin convinces Harold to help him win the challenge and Courtney's heart to which Harold agrees as he does not want Duncan to win either. However, Justin later betrays Harold in order to claim the prize all for himself and even claims that Harold would have done the same thing if Leshawna was the prize. During the final moments of the challenge, Harold criticizes Justin for his hypocrisy when the latter describes himself as a fair knight. After Justin is eliminated, Harold bids Justin farewell in many ways which clearly annoys him. After the second season ends, the two of them form the The Drama Brothers along with Cody and Trent.
In Aftermath: Bridgette Over Troubled Water, Blaineley shows a video featuring Harold annoying his fellow campers back in season one. In one of the clips, he tells Justin about the human bladder being the size of a football when it is full while Justin is urinating. Annoyed, Justin punches him. In a different clip, Justin is seen wearing boxing gloves and is about to attack Harold along with Beth, Heather, Cody, Chef Hatchet and a bear while he is explaining a complicated mathematical equation to them.
When Harold first meets Leshawna, he immediately develops an attraction to her. Their first conversation, however, is uneventful as Harold accidentally makes Leshawna mad by unknowingly insulting her. Nevertheless, Harold had been secretly sending her love poems and by the time of his elimination, he confesses his love for her. Upon hearing this, Leshawna shares a kiss with him before he takes the Boat of Losers. However, when the two meet again during the special, Leshawna breaks up with him, claiming that they are moving things too fast and that she felt sensitive at the time. Harold takes this well but does not give up on getting her to date him, believing that he will be able to win her back.
Throughout Total Drama Action, Harold would try and impress Leshawna but would have little to no success. Though Leshawna continues to reject him, she still defends him from Duncan's bullying. Upon finding out that Leshawna had been lying to claim a reward for herself, Harold is torn between his team and his love for Leshawna. He defends her but when the contestants found out that she also insulted everyone during her trip to the spa, Harold is heartbroken and loses trust in her until she sings an apology cheer. Because of this, Harold and Duncan decide to vote off Heather instead of Leshawna. Upon reaching the merge, Leshawna successfully pulls both Duncan and Harold into an alliance with her, something she has been trying to do earlier on in the season. However, the two would go behind her back and form their own alliance with Justin and vote her off. Despite this, Leshawna forgives Harold and the two part in good terms. Harold frequently mentions Leshawna after her departure, even naming a snail after her in Crouching Courtney, Hidden Owen.
The two are placed on the same team again in Total Drama World Tour, though Leshawna seems to be more impatient with Harold and pays more attention to newcomer, Alejandro, than him. After being eliminated as a result of Alejandro's treachery, Leshawna apologizes to Harold for her mistreatment towards him. As of now, their relationship is strictly platonic, though Harold's love for her is still strong.
Harold and Lindsay have limited interactions in Total Drama Island due to them being on different teams.
In Million Dollar Babies, Harold and Lindsay are pitted against each other for the boxing match as Chris states that they had the worst performance in the training course. The fight between the two goes back and fourth but ultimately, Lindsay is able to knock out Harold with a powerful punch. Despite this, Harold is declared the winner of the challenge as he gained extra points for performing in slow motion. In Rock n' Rule, Harold agrees to help Lindsay and Beth vote off Duncan in order to make Courtney mad. However, the plan fails as Lindsay accidentally votes for herself instead. As she enters the Lame-o-sine, Harold, Beth and Owen bid her farewell.
The two of them are placed on Team Victory in the third season but due to Harold's early elimination, they didn't have much interaction that season. In Hawaiian Punch, both Harold and Lindsay are chosen as helpers for the finalists, but are on opposing sides. They end up fighting each other, until Cody distracts Lindsay and she runs off.
Several times in the series, Noah is shown to have a great dislike towards Harold for telling him useless facts and information. In Total Drama, Drama, Drama, Drama Island, while the contestants are at Playa Des Losers, Harold tells Noah some facts about beavers, though the latter has no interest whatsoever, and points a mock gun to his head. When Harold offers to lend his journal to Noah if he promised not to ruin it, Noah sarcastically says "No thanks. I'm good."
In Walk Like An Egyptian - Part 1, Noah is once again annoyed by Harold as he begins to talk about the difference between aerophobia and aeronausiphobia. After he leaves the bus, Noah sarcastically tells Harold that he will be "aero-nauseous" of him if he keeps telling his "fascinating facts."
In a clip shown by Blaineley in Aftermath: Bridgette Over Troubled Water, Harold is seen telling Noah that in Alaska, it is illegal to talk to someone while moose hunting. Suddenly, an actual moose appears and rams Harold against a tree, much to Noah's shock.
Aside from a heated dodgeball challenge, Owen and Harold didn't interact much in Total Drama Island, though Harold did support Owen when the latter reaches the finale of the season. The two of them are still on opposing teams in Total Drama Action, but they had more interaction than last season since all the boys are staying in the same trailer. After Owen returns to the season, he and Harold get along very well. However their friendships becomes challenged when Harold comes to realize Owen sabotaged the challenge in 2008: A Space Owen, leading them to try vote each other off, but Harold gets eliminated due to having the most votes. This hostility appears to have subsided by Total Drama World Tour where they are shown getting along again.
In Up the Creek, Duncan chooses Harold and Sadie as his canoe partners in the beginning of the episode. In If You Can't Take The Heat..., Harold and Sadie are partnered together for the cooking challenge with the two of them cutting the cheese. Throughout the episode, Sadie laughs at Harold when he gets repeatedly pranked by Duncan, DJ and Geoff.
In Haute Camp-ture, Trent feels sorry for Harold, who is hiding from Courtney, and gives him some food. When Ezekiel asks Trent why he is still helping Harold, he said that Harold doesn't deserve to starve even if he is a traitor. After Courtney finds Harold, Trent laughs at his misfortune.
In Monster Cash, as the cast begins to push each other while exiting the cart, Harold knocks out Trent with a karate chop. In Beach Blanket Bogus, Harold supported Duncan's idea that Trent's obsession with the number nine has something to do with his feelings for Gwen.
After Total Drama Action had ended, the two of them, along with Justin and Cody, formed the Drama Brothers. However, the band broke up after Trent insulted Harold's beat-boxing, leading Harold to go solo. Despite this, the band eventually got back together.
During the Aftermath shows of Total Drama World Tour, Harold, Trent and Justin will play back up for some of the songs. In Aftermath Aftermayhem, Harold and Leshawna have an off-screen bet with Trent to see whether or not Lindsay remembers Tyler, in which they won.
In Dodgebrawl, Harold spits some water on Tyler while getting a motivation talk from the other teammates. Tyler cheers for Harold, along with the other teammates, when the latter wins the challenge for their team.
In Super Happy Crazy Fun Time Japan, Harold and Tyler are seen hugging each other for dear life while they are singing Before We Die. The two of them are excited about the upcoming challenge as they both love Japanese game shows and begin to talk about their favorite scenes from "Human Itchi My Car Go-Go."
