Grand Chef Auto

'''The teams are merged as the host sends the players on a challenge that someone quickly takes control of. Due to one person's slip-up, someone with a secret is forced under another until they finally stand up to take control and save their crush. Although someone appears to have a come-from-behind victory after being betrayed, the host gives the rewards to the original winner, which allows them to eliminate a cured camper.'''

Plot
The episode starts with Chris waking up the campers with an old alarm and tells that he has a treat for them: the teams are merging. Jo is happy about the merge but decides to keep Lightning as an ally. Chef then drops a giant block of cement on the Maggots cabin with a helicopter, destroying it, leaving the Maggots to sleep in the Rats' cabin. Chris says that he built a mountain with his face named Mount Chrismore. The Maggots complain about their belongings being buried by the block, so Chris allows them to recover their belongings. Cameron tries to make an alliance with Jo, but she refuses.

Zoey has problems retrieving her clothes from the rubble, so Mike offers her an extra pair of Brick's boots. The boots' smell causes Zoey to fall but Mike catches her. Meanwhile, Scott jokes Mike about his multiple personality disorder and Cameron begs him to not tell anyone and instructs Scott how to keep Mike present. Chris brings Duncan to demonstrate the challenge but he runs to the forest when Chris frees him from his tying. Chris gives the instructions of the challenge: the contestants must find the hidden keys in the kitchen to Chef's vintage go-karts and then drive them to three different landmarks and leave their mark in them. First to finish wins. Chef scolds Chris for letting the campers drive his kart collection but Chris ignores him.

Scott tells Mike to help him or otherwise he will tell Zoey about his personality disorder. Mike is shocked that Scott knows this, but reluctantly agrees to help him. In the kitchen, the contestants search for the keys. Scott repeatedly asks Mike to do things for him which Mike angrily does. Zoey notices this and is confused to why he would do so. Eventually everyone finds a key. Cameron finds his under a table, Zoey's in a bucket, Lightning's behind a pantry, Jo's in the trash, and Scott's in a jar. Mike finds a gold key and Scott tells Mike to give it to him, which against his will, he ends up doing.

General

 * The Mutant Maggots and the Toxic Rats merge in this episode.
 * Mike finally is cured of his multiple personality disorder in this episode.
 * After Mike conquers his other personalities, for a brief moment, a small shadowed Mike with a mischievous face appears in midair in the background.
 * Mike's elimination is similar to Gwen's elimination in The Chefshank Redemption, in which they were both blackmailed by the antagonist, who found out of their secret in the previous episode, to help them win.
 * This is first the time in Total Drama history that the winner of the challenge gets to decide who is eliminated.
 * This is technically the second time that one person alone got to choose who went home, the first being Courtney in Ocean's Eight - Or Nine. However, that was originally intended to be a regular elimination, and only after the other votes were wasted on the invincible Courtney did she get to choose for herself.

Continuity

 * This is the second episode starting with a merge in which a male is eliminated. The first was Owen in Niagara Brawls.
 * This is the first episode starting with a merge in which a male has won the challenge, not including Courtney and Duncan who won the challenge together in Niagara Brawls.
 * The first part of the challenge involving searching for keys throughout a section of the camp is similar to the challenge from Search and Do Not Destroy.
 * This episode has the biggest participation of Chef Hatchet in Total Drama: Revenge of the Island yet.
 * The Chris doll Chef used for his message is the same doll Chris used to fake his death in Get a Clue.
 * This is the fourth time a couple's kiss is interrupted before they were seperated. The other times are Gwen and Trent in Search and Do Not Destroy, Izzy and Owen in Full Metal Drama and Lindsay and Tyler in Can't Help Falling in Louvre.

Goofs

 * When Scott picks up Mike to cover him, his shirt is tucked in. But when he runs with Mike his shirt is normal.
 * When Mike wakes up after winning the fight with his alternate personalities, his shark tooth necklace is gone.
 * This could be because the necklace belongs to his Vito personality and not Mike. This may be false as he wore it when he became Mike and Svetlana in Finders Creepers.
