Scarlett Fever

'''With the island's secret leading to potential meltdown, the host forces the remaining campers to stop its destruction. While two unlikely partners work together and another fawns over her help, one finally reveals her true nature and takes over in order to gain the prize for herself. In the end, she finally stopped and eliminated, but not without the host also removing a partner after becoming sick of "evil contestants" on the show.'''

Plot
The episode begins from where the previous one left off, the island being revealed to be artificial and all it's mechanical parts continuing to go haywire. All the remaining contestants demand to know what's going on. Chris continues to pretend to not have a clue and that everything was functioning normally. However, when several trees pop out, then retract behind him, he gives in and confesses the truth. He explains that Pahkitew Island is artificial, complete with robotic animals. However he is unfazed by the chaos and denies there is anything wrong. However a monitor appears out of the ground and signals the island will self-destruct in one hour. Chris then announces the new challenge, for the contestants to travel to the control room and cancel the self-destruct. Chris shows a display depicting the location of the control room, which Scarlett excitedly snatches. In the confessional she states how Chris has handed her control of the island, before laughing evilly. Chris explains that there are three possible entrances, so they would each be divided into three teams of two. Unsurprisingly Jasmine and Shawn form a team, as well as Max and Scarlett, which leaves Sky, to her dismay, with Sugar.

Jasmine and Shawn head towards an entrance hidden in a lake. Along the way they have to dodge many obstacles such as mountain formations bursting out of the ground, and flame streams. When they finally reach the lake, Shawn sees sharks in the lake and becomes hesitant, however Jasmine reassures him that she knows how to deal with sharks based on a technique she had seen on TV (punching them in the nose). Shawn reluctantly follows Jasmine into the lake, where they cone across the entrance hatch sealed with a wheel. As Jasmine loosens the wheel a shark approaches, but just like she said, she punches it in the nose and knocks it back. However her tactic is not very reliable as the shark immediately swims back. Shawn wets himself in fear, and the smell repulses the shark so much that it swims away. The two finally enter through the hatch and enter a metal corridor. Chris then appears on a monitor hanging on the wall. He states his delight that he would be able to salvage footage for an episode, which angers Jasmine. He also explains that the corridors were patrolled by robotic animals, and that Jasmine and Shawn must maneuver through an assortment of motion detecting lasers. If they failed to do so all kinds of crazy security protocol would be triggered over the island. Initially Jasmine and Shawn both skillfully weave through the motion sensors, but they get distracted by each other and kiss. No longer evading the motion sensors, they get set off, causing the island's defenses to send several robotic animals to attack them. The two of them flee in the opposite direction, only to discover a mechanical door is closing shut. Shawn and Jasmine slide under the door, however Jasmine notices that she dropped her hat. She reaches under the door to retrieve it, but one of the robot animals' heads manages to bite onto it. As Jasmine pulls her hat out, Shawn alerts her of the robotic head attached to her hat, which she punches away.

Meanwhile Sugar and Sky journey towards their designated entrance. They discover some holes in the ground, and assume they lead inside the island. However trees continuously rise and fall from the holes. Both girls attempt to jump down a hole, but end up getting stuck. Scarlett and Max have also made it to their entrance point, which is supposed to be a rock. However they discover there is are countless identical looking rocks scattered in the area. As Max begins to pester Scarlett she suggests she asks the rocks which one of them was the real one. Max loves the idea and tells Scarlett she isn't "completely useless", he begins to demand the rocks tell him, but when he kicks a rock it slips open and reveals the secret passage, to which he falls down. Scarlett grins smugly and states that perhaps Max wasn't completely useless either before jumping down.

Back to Sky and Sugar, the girls finally manage to descend down the hole, after being pushed up by a tree then riding it down. In the cavern underground, they notice a room full of gears and wheels which cause the trees to rise and fall. Sugar sees a bird's nest in one of the trees and eats the eggs, before burping a live bird out of her mouth. Chris then appears on the screen and gives them updates about the situation, including how Shawn and Jasmine had set off security measures causing robotic animals to roam the halls. A door then opens and a seemingly adorable cat comes through. Both Sky and Sugar immediately find it to be cute, but Chris warns them in time for the cat to open up its mouth and shoot a flame. Given the choice between the cat-bot and the gear chamber, Sky and Sugar choose the latter option. They continuously run and pause to avoid getting crushed by the constantly moving gears.

Max and Scarlett are the last to reach the island's interior, but land closest to the control room. Chris congratulates them but also informs them that the door is sealed by a keypad which is set to give an electrical shock each time an incorrect combination is inputted, and unfortunately the combination was kept inside the control room. Max tries a few combinations and gets shocked repetitively, even putting in a combination he had already entered. Scarlett watches in satisfaction and encourages him to keep on trying, knowing that given enough attempts the panel would eventually short out. Her deduction is correct and she is given access to the control room. Scarlett approaches the computer and it greets her as "Chris McLean", Scarlett then undergoes a change in nature, proclaiming that the island is hers, and laughs evilly. Max approaches, unaware of Scarlett's new nature, and believes she is going to pass on to control to him. However, Scarlett turns around and takes off her glasses while letting her hair down, revealing a much scarier looking Scarlett. Although Max is initially not phased, simply stating she "looked different", he quickly becomes terrified as Scarlett picks him up and states that she is "EVIL!" Max is then shown huddling in the confessional sucking his thumb after Scarlett's revelation. Scarlett then sets Scuba Bear to get rid of Max, who pulls off its exo-skin and reveals itself to be a robot. Scarlett then gets in contact with Chris, who is also surprised by Scarlett's change in appearance. Scarlett then proceeds to threaten Chris by telling him she has control of the island and will let it blow if he does not give her the million dollars. Chris however doesn't comply and feels she is bluffing, but when Scarlett fires several of the rockets (disguised as trees) at Chris's helicopter he thinks otherwise. Although Chris is scared now he still refuses to hand over the money, telling Scarlett the other contestants would arrive soon. However Scarlett is unconcerned, having already planned for this.

Just at that moment, Shawn and Jasmine walk along a hallway in time to see Sugar and Sky fall from a hatch in the roof. All are happy to be reunited, especially Sugar who is unable to contain her excitement, eagerly telling Jasmine of the adventures they just had. Right on queue, Scarlett delivers a message to the contestants, telling them that Chris lied, which they have no trouble believing, and tricks them to going to another room, under the guise that it was the true location to shut off the self destruct. However the contestants arrive in the room only to find it filled with hundreds of robots that looks identical to Chris. Scarlett then remotely shuts the door and gives one final taunt that they were all going to die before signing off. All of the Chris robots activate and trundle towards the contestants with their arms outstretched while chanting "Total Drama". All of the contestants huddle together in fear while awaiting their demise, with Jasmine commenting it was just like a horde of zombies. However hearing the word "zombie" sends Shawn into a combat mindset, and he fearlessly charges forward and massacres all of the Chris robots, to everyone's surprise. Jasmine then states in the confessional that "there is a time a girl accepts her boyfriend for who he is." Scuba Bear then shows up, but Shawn throws one of the robot legs and it lodges into Scuba Bear's head and it explodes, to which Jasmine sighs at. Chris finally decides to contact the contestants and isn't happy about what Shawn did to his "Promo-bots". He explains that Scarlett had gone rogue and tells them what she has planned, and that he still refused to accept her terms.

The contestants make their way to the control room, where Sky attempts to reason with Scarlett, however Evil Scarlett shows up on the monitor and informs them if their impending demise due to Chris's continuous refusal. Sky then devises a plan to trick Scarlett. Scarlett sees a message seemingly accepted her terms. Satisfied that she has won, Scarlett opens the door only to be shocked in discovering it was actually Max holding one of the decapitated Chris Promo-bot heads to pose as Chris. He gloats that he tricked her and that he was more evil, but this only infuriates Scarlett who very nearly attacks him in anger. However Max is saved by Sugar who tackles Scarlett to the ground and ties her up using her own hair. Despite this minor victory the danger has not yet subsided as the countdown to the islands self destruction continues with only seconds left on the timer. Sky frantically tries to shut it down, until Jasmine suggests using "Ctrl Alt Delete" which succeeds and saves everyone's lives. Chris then shows up again to the contestants' annoyance. Max process to taunt Chris in saying his ugly looks helped them out fir once, while holding up the Chris head, only for him to get shocked again. Despite the self destruct being averted, Scarlett's tampering still had major alterations, leaving one side of the island on fire while the other half us frozen solid.

At the elimination ceremony Chris states a change in the usual process. Instead of handing marshmallows to those who were safe, he proceeds to pelt them at Scarlett's face, who is tied up and ready to be fired in the Cannon of Shame. Max however then proclaim that with Scarlett eliminated, he was now the "one true evil" and he would take over from where Scarlett left off. But Chris has had enough of evil and orders Chef to snatch up Max and shove him in the Cannon as well, to Scarlett's dismay (who pleads for anyone but him). Chris then fires the two villains off the together, before signing off the episode.
