Backstabbers Ahoy!

'''As one team deals with their newest member, the other is severely divided by one contestant, who shares feelings for two girls at once. When the contestants' most prized possessions start vanishing, one player initially accuses their teammate, but then places the blame on someone else. Although they figure out the true scheme, it is not enough to prevent elimination.'''

Plot
At the beginning of the episode, the Rats are seen peacefully asleep, until Brick, their new teammate, had woken his team by his alarm clock. This causes the other Rats not to be too thrilled about him now being on their team. So as Revenge, Scott tries to put Brick's alarm clock down the toilet in the confessional but fails when the toilet breaks because of the alarm clock.Then in the Maggots' cabin, Mike is changing his personalities in his sleep, to Svetlana, Vito, and Chester, and Cameron records them as he finds it fascinating. Meanwhile, Dawn is seen by the campfire pit, picking up firewood and putting it into a trash bag. Brick comes over to assist, but Dawn replies by saying he shouldn't have to help because of him being teased, which Dawn sees in his aura between his bladder control issues and need to be dominated. Jo then comes over to taunt him by saying she is whiping her team into shape. The camera then pans over to Cameron, who fails to do a pushup. Back in the cabin, Lightning discovered his protein powder was stolen, which Sam, focused on playing his video games, doesn't seem to think is that big of a deal. Scott then tells Lightning of his "suspicions" towards Brick. At the mess hall, everyone is seen eating when Chris announces it's challenge time, and that they have 10 seconds before he releases the raccoon. Everyone doesn't take it seriously until a giant raccoon is shown. Lighting was the only one not to hear the warning since he was in the basement looking for more protein, but the raccoon eventually throws him out the window of the mess hall.

At the dock, the first challenge was announced. Chris then shows one of the classic players to help demonstrate the challenge, which is Bridgette. She reminds Chris of her contract stating only to do a demonstration, but he replies by saying it's not needed. Instead, he makes her chum the water with Dakota, which attracts Fang. The challenge is then revealed that both teams have to first go underwater to retreive water skiis for the next challenge wearing an old-fashioned diving suit, while the others pump air into the suit. The two divers are Jo and Brick, as they head underwater, they start to race for the skiis. Up above, Zoey is seen standing on the air pump, while Mike explains that he didn't know how he ended up kissing Anne Maria, and that he gets so deep into "character." Zoey tries to understand what he's saying, and thinks he's a method actor. Mike quickly agrees and compliments her by saying she's the most amazing girl he's ever met. Back down in the water, Jo has ran out of air because of Zoey. Anne Maria shoves her off the pump, causing Zoey to slap her in retaliation, and ends up getting orange spray tan on her hands. Anne Maria gets angry and pushes her down, tearing Mike's shirt in the process. Mike then turns into Vito and Anne Maria cuddles with him. Zoey is then offended and walks off in disappointment. Scott then gets bored and wants to widdle something with Fang's shark tooth. But he couldn't find it and blames it on Brick for stealing it. Anne Maria then defends him, but couldn't find her hairbrush, and then takes back what she said. Back down in the water, Brick is getting tossed around by Fang and breaks his air pump, releasing him in a wild manner and hitting his skiis, allowing them to float up to the surface. Nearby, Zoey is drawing in the sand a broken heart, while Dawn tries to comfort her by saying the Mike parts of him are in love with her. She didn't understand what she meant, so she turns around only to find she had disappeared.

In part two of the challenge, Chris shows the rewards. The Rats won a speed boat, while the Maggots won a dingy, which they will race to shoot mutated gulls at nearby mines, and whoever hits 4 wins. Dakota swims over with Bridgette to the mine, and acitvates one, causing both of them to be blown out of their canoe, which makes him laugh and change the goal to 3 of them. While in the water, the Maggots skiing, which is Cameron, Mike, and Anne Maria, are being followed by Fang the shark. But the boat couldn't get out of his mits because of how slow it was, and Anne Maria accuses the driver, Zoey, trying to sabotage the team. Then Mike, still as Vito, punches the shark away from them. Back on the boat, Jo tries to slow down the Rats ahead of them with the mutated gulls. She hits the back of the Rat's driver, Lighting, and he passes out by the venom of the gull. The boat then steers out of control and into weeds, causing the Maggots to catch up. Scott then fired his first gull at the bell, but didn't seem to be real happy of his achievment. The camera then pans back to the Maggots still behind. Anne Maria is afraid of losing, so Cameron tries to change Mike into Svetlana, in hopes of her helping with the challenge. Lighting is then seen trying to regain contiousness, but hits the controls, and the boat stops, causing the skiiers to crash into the boat. Mike then changes into Svetlana and hits one of the mines and gets away in time before it exploaded, and the Maggots take the lead. Dawn then tries to get her team back in the game by Sam driving, while Brick and her use Lighting as a new water skii, and told Scott to not fire any gulls. He say he wouldn't, then shot a gull, and then said he'd start now, wasting one of the three gulls they need. After Jo has seen the Rats have gotten back under control, she tries to shoot another gull at them, but the cannon had malfunctioned. Zoey didn't see where she was going when turning to check on Jo, and crashes into some rocks. The Rats regained 1st and saw the last mine. Scott didn't want to win though, so he wastes his last gull and shot Sam in the back, causing him to pass out as well, and Scott pretends and doesn't know how it happened. Jo then is seen throwing Cameron to hit the last mine, while the Rats crash, causing Lighting to fly in the air. They both collide and land on the last mine. Back at the dock, Chris watches the explosion, and declared Cameron and the Maggots the winners, for landing on it first. The Rats are then washed up on the shore, and Sam didn't know how he passed out. Scott tries to save himself by saying Jo had a lucky shot, but Dawn didn't believe it.

Back at the campgrounds, Dawn then makes a confessional stating that Jo's cannon was jammed, so the only person to have shot a gull was Scott. She then swore to Mother Earth to expose Scott for the traitor he is. She then leaves the confessional not knowing Scott was listening to her the whole time. In the cabins that night, Scott then goes after Dawn for not letting him shoot at the Maggots, Sam then tells that he is still mad over Brick "stealing" everything. Dawn and Brick then enter the room, Scott then picks up Dawns bag and drops it, revealing all of everyone's stolen items. Scott pinned it on Dawn for becoming too smart on his plan.

At elimination, Brick, Sam, and Lighting were all safe. Leaving Dawn and Scott as the final 2. They exchange glares at each other, until Chris reveales that the one leaving is Dawn. She then states that she had found the Chris head. Chris then asks where the seal of approval was, and Scott revealed it was one of his decoys. Dawn is not as upset because she still had the discareded TDRI souveniers, and proposed to sell them on Crug's List, so she could donate the money to start a sanctuary for all the mutated animals on the island. She then also tries to show who the real traitor of the group is, but Chef baggs her before she could say anything, and then takes the Hurl of Shame, putting her at 10th place. Chris then signs off, and Dakota is still seen holding on a boey,
