Duncan and Leshawna

This article focuses on the interactions between Duncan and Leshawna.

Overview
Duncan and Leshawna's conflict arises mainly due to their clashing personalities and their equal desire for power. Leshawna also has a personal dislike for Duncan because of his constant bullying of Harold, for whom she has a soft spot. Even though it seems to be settled in Trial by Tri-Armed Triathlon (after Duncan opens up to her about his softer side), the conflict reignites in Total Drama Action once Duncan and the rest of their team discover that Leshawna faked her crying in order to get the reward for herself. Although this doesn't stop Leshawna from trying to make an alliance with Duncan and Harold, this effort also fails and results in her later elimination.

Basic Straining
When Leshawna sinks into the mud, Duncan mockingly salutes her.

Search and Do Not Destroy
Leshawna tried to persuade Duncan to vote off Trent or Heather to cheer up Gwen about Heather kissing Trent. When Heather won immunity, Duncan followed Leshawna's orders and voted out Trent.

Hide and Be Sneaky
Leshawna supports voting out Duncan, calling him a "criminal" and stating that she does not trust him.

Trial by Tri-Armed Triathlon
Even though Leshawna and Duncan had problems in the beginning, they grew to befriend each other in this episode when they realize they have some things in common.

During the first of three challenges, each team, Duncan and Leshawna being one of them, had to choose who would eat a meal to win the challenge point. They have an arm wrestling competition to determine who it would be. Duncan cheats his way to the win, and gets to eat. Leshawna gets furious and begins to stuff food into his mouth, despite him asking her to stop.

As they head over to their canoe to begin the next challenge, Duncan tells Leshawna that he is leading them to Boney Island. Leshawna then replies that she needs to lead them due to how much she had gone through when she was little. Duncan was going to say that she was much bigger, referring to her weight, until Leshawna forces him not to finish that sentence. En route to Boney Island, Duncan once again tries to act tough in front of Leshawna  that she knew about "Bunny" because Courtney had told her about this incident off-screen. Duncan then comes clean, and tells her that he knew from experience how DJ felt after losing a pet, because his dog Petey had ran away from home when he was six years old, and he didn't want DJ to suffer like he did. Leshawna tells Duncan that his secret is safe with her.

Once they reach Boney Island, when one has to piggyback the other, Leshawna suggested Duncan carry her, but he refused, saying that he could only carry three-hundred pounds. She then tackled him to the ground.

At the final challenge, Leshawna helps Duncan to stop Chris' taunting after he saw his and Courtney's initials on the back of the wooden head of Courtney by throwing another head at him to knock him out. She then tells him that people don't need to be tough all the time.

Riot On Set
After watching Duncan's performance, Leshawna, along with Chef, Chris and Heather were moved to tears.

3:10 to Crazytown
Leshawna notices Duncan is picking on Harold a lot. She claims that she has her eye on Duncan, which also shows signs of her getting defensive of Harold.

One Flu Over the Cuckoos
When Leshawna proposes that she, Duncan, and Harold form an alliance against Heather, Duncan laughs at the idea of partnering with Harold, annoying Leshawna. During the first hospital challenge, Duncan pulls down Harold's pants, revealing his red underwear. Leshawna tells him to back off and tells Harold not to take that kind of treatment.

Leshawna and Duncan agree on working together to help all the other castmates as they were the only contestants that didn't get a "disease." Later, when Harold is afflicted with a phony disease, Leshawna knocks away Duncan when he attempted to stick a rectal thermometer in Harold's mouth. Following the challenge, Duncan agrees to letting Leshawna have the prize.

The Sand Witch Project
When Duncan is making fake blood in this episode, Leshawna gives him respect, saying that it looks very realistic. She is quick to withdraw her respect when Duncan revealed he and his brothers have used the fake blood to scare kindergartners and that he had once given twelve five-year-olds seizures.

Masters of Disasters
When Leshawna accidentally admitted she faked her crying two episodes earlier, Duncan, along with Heather, was very angry with her, and perhaps the angriest of all the other Gaffers. Upon finding out about her deception, he pointed a finger at her and angrily declared, "You're a total sham!"

Full Metal Drama
Duncan continues to bring up what Leshawna had done three episodes ago. He even made the comment that as far as he knows, she is basically "off the team." Despite this, Leshawna along with Heather allows Duncan takes in charge of the first round of the challenge in favor of Harold.

Ocean's Eight - Or Nine
Duncan refuses to let Leshawna forget about her lie to the team, even turning Harold against her. Leshawna swears revenge on all of them when she gets locked in a vault for the bank heist challenge. Duncan convinces the team to abandon Leshawna in an attempt to catch up with the Killer Grips, saying he didn't need the bank robbery equipment locked in the vault with Leshawna, leaving her in the vault for the entire day, further deepening the enmity she feels towards Duncan.

Million Dollar Babies
Like everyone else, Duncan was angered when he watched Leshawna making some rude comments about the other contestants during her spa ride with her cousin, Leshaniqua, from a video on Courtney's PDA. Despite the animosity towards Leshawna after seeing the video on Courtney's PDA, Duncan decided to side with Leshawna instead of Heather. He liked Leshawna's apology cheer, and decided to join her and Harold in voting off Heather.

Dial M for Merger
After Leshawna is complaining about the food, Duncan is glaring at her, along with everyone else, due to Leshawna making rude comments about the other contestants in the previous episode. Duncan then admits that he trusts no one, but himself. Leshawna also attempts to form the alliance between herself, Duncan, and Harold again, but succeeds this time.

Super Hero-ld
Duncan and Harold dump Leshawna in their new alliance in order to join Justin to form the new guys' alliance. Leshawna also betrays the alliance by teaming up with Lindsay and Beth to vote Duncan off as it will mess with Courtney's head. At the elimination ceremony, Leshawna was successfully vote off. As she's leaving, Leshawna tells Harold to stand up for himself and "kick Duncan's butt."

Leshawna's Lame-o-sine
Leshawna is admittedly surprised she was voted off, and didn't expect that her "mani-pedi" would cost her the million dollars. She does not blame Harold for voting her off, and immediately believes that Harold was bullied into it by none other than Duncan. Leshawna's anger begins to reach its boiling point as she steams that that was just one more reason why she couldn't stand Duncan. Leshawna suddenly explodes, ripping a cushion off the Lame-o-sine and smashing it into the window in rage. The tape is cut off, but returns to find Leshawna has cooled off, not without destroying the interior of the limo. She then threatens Duncan over the tape, warning him that she is coming for him, and that if there is a single scratch on Harold, "Leshawna will be gettin' all up in your business!"

Crouching Courtney, Hidden Owen
When Harold was talking about how delicate Leshawna was, Duncan said that she was about as delicate as a freight train, prompting Harold to punch Duncan.

The Aftermath: IV
Leshawna is in awe when she saw a video of Duncan showing his sweet side.
