Harold and Heather

M'LadyShipping is a belief in a romantic relationship between Harold and Heather. The 'Ship was at first a small friendship and a conflict, but in Riot On Set when Heather needed help Harold helped her and called her M'Lady.

Total Drama, Drama, Drama, Drama Island
When the cast begins to split up into teams, all of the campers find partners except for both Heather and Harold. At first, Heather refuses to team up with Harold, but as she was desperate for a partner, she reluctantly agrees to take him along with her. Harold manages to steal away the brief case from Owen, Tyler, DJ and Cody, which Heather is impressed by. After being betrayed by her, Harold rows next to Heather in a canoe, who is once again alone and tells him to go away. Harold says that Heather does not need to be so mean, which is why no one wanted to partner with her. Heather admits to Harold that she never wanted to be the person everyone hates, and Harold seems to empathize with her. He offers her a ride back to camp and wonders if the two will be friends after the show is over. Heather said that would definitely be the case, but her gestures afterward are questionable. After being chased into the ocean by LeShawna, Harold is seen helping Heather out of the water, only to be knocked back into the sea just in time to qualify for Total Drama Action.

Riot On Set
Heather and Harold are both on the Screaming Gaffers. When Heather says they should pass the film equipment up like batons, Gwen remarks how if Heather says it, they would not do it. Harold, however, agrees with Heather saying it is a good idea and that she should bring up her ideas at the next team meeting, where he will second her. Later, Heather's foot is trapped in a light cord, hanging her upside down. Harold arrives calling her "M'Lady" and helps her down to which Heather weakly mutters thanks. In a confessional shortly after, Harold admits that he's been working on his courting skills, while Heather admits that Harold would be an easy person to string along with an alliance.

The Chefshank Redemption
Harold reveals he's slightly attracted to Gwen and begs that neither LeShawna or Heather or Gwen find out, this proves that he is willing to be friends with Heather, adding that Harold is the camper Heather dislikes the least.

Master Of Disaster
Heather encourages Harold to hurry while he's opening the hatch.

Full Metal Drama
Heather helps Harold comfort LeShawna while she's bloating.

Not Quite Famous
Harold allowed Gwen to use his red ant farm to get back at Heather for reading her diary out loud on national television, although he is never actually told what Gwen will do with it. But he most likely didnt know what she was going to do with it.

Paintball Deer Hunter
When Bridgette feels that she can't play paintball because she doesn't approve of hunting, Harold specifically reminds Bridgette that she could hit Heather with a paintball, after which they grin evilly.

X-treme Torture
During the final challenge, the campers were to water-ski in mud to collect flags and reach the finish line. The flag-catcher was designated to be driven by a member of the opposing team, meaning Heather would jetski Harold as he collected flags. Before and during the challenge, she called him "Alpha geek", "dorkwad", and "guppy". Despite Heather trying to make it difficult for Harold to catch his flags, he ends up catching them all and Heather is forced to cross the finish line and allow the Killer Bass to win.

Not allowing this to happen, Heather plotted to cut the rope tied to the jetski to render Harold stranded and therefore fail the challenge. However, a wayward tree brand snaps Heather's top off while she is about to cut the rope, leading to Heather accidentally flashing her bare breasts to Harold, which mesmerizes him to the point that he crashes into a rock, losing all of the flags and the challenge, which ultimately causes him to get voted off the island. After Harold is eliminated, he reveals that he was the one who wrote the love notes to LeShawna and he had a crush on her, not before reminiscing about seeing Heather's breasts over and over. (See the SugarShipping for more details.) After this, Heather calls Harold a dweeb, saying the incident was a fluke. This explanation did not work for LeShawna, who began to chase her off into the night.

Haut Camp-ture
Harold says Heather was the scariest female on the island, but that he could take her (most likely because of the aforementioned incident in X-Treme Torture) just before Courtney beat him senseless with a lamppost.

Total Drama, Drama, Drama, Drama Island
Initially, Heather rejected Harold's offer to become partners, but when it turned out that there was no one else left for Heather to partner with, she recruited Harold only on the condition that he would not talk to her. She was militant about this rule, often shutting him up once he started talking. Once Harold and Heather managed to steal the case from Owen, Cody, Tyler, and DJ, Heather hit Harold in the groin with the case and took off on his hand glider by herself, effectively breaking their alliance, but Heather winds up falling off the cliff and lands head-first into a beaver dam. Harold just looks down in disappointment, saying the hand glider was not his best work (rather than showing any concern for Heather's wellbeing).

After reconvening at the river with Harold on a canoe, Harold only allowed Heather to rejoin him for a 60-40 split on the money, saying that without his help, the beavers would be back for her soon. After he asked Heather if they could become friends after this adventure, Heather assured him they would, but quickly looks to the camera that indicates that she was not sincere. When LeShawna nearly ran over Heather with a four-wheeler straight into the water, Harold found it "awesome".

Alien Resur-eggtion
As there were limited paths to take in the alien egg challenge, Heather was with most of the group, much to their chagrin. When it came down to herself, Harold, Owen, and Izzy, Heather proposed they follow her to their intended goal. Everyone is hesitant at first, and Izzy reminds Heather that they dislike her, so Heather clarified that they follow her with no intention of forming an alliance and simply reaching their intended goal for themselves. Only when Heather worded it this way did Harold agree to join her.

Riot On Set
When Harold agrees with Heather about her idea of passing the film equipment like batons, Heather responds by telling Harold to jump in a lake and then calling him "Trout lips". After Harold's acts of chivalry in helping Heather after some mishaps on the stage, Heather states in the confessional that Harold would be an easy person to form an alliance with. Judging by how she has treated her former alliance-mates and knowing that Harold is smitten with LeShawna, who is a mortal enemy of hers, chances are this alliance will be as controversial as Heather's previous alliance. When the Screaming Gaffers try to pick a person to play a "tough guy" for their act, Heather states that Harold is as tough as butter.

Beach Blanket Bogus
When Harold prides himself on his buttocks, he says he has to appease his lady fans as an excuse for not participating in the surfboard challenge. After he says this, Heather says out loud that when Harold refers to his "lady fans", he really means his mother.

Master Of Disaster
In the begining of the episode when Harold is explaining how he had a kidney swap surgery as a child, he adds that he is a rare case, but and Heather then adds that he sure is a "rare case" in a different way then Harold meant.

Full Metal Drama
Heather laughs at Harold, along with the rest of the Gaffers, when Duncan mocks him and invokes pain upon him with Harold's "Nun-Yos".

Ocean's Eight - Or Nine
When Heather calls Harold a Nerd, He blows a raspberry at her. Also, they tried to fight to open the safe before Duncan thought of LeShawna's actions.
