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 opens 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.

Out at the go cart alley, Chris gives everyone a can of spray paint and GPS device. Their mission is to tag three landmarks around the island, The Rock Wall of Mt. Looming Disaster, the spooky tree in the haunted forest, and the top of a giant totem. Chris also says everyone will have to steal their go carts from Chef in order to drive. When everyone gets to Chef, he releases the laser-eyed squirrels. Scott uses Mike to cover him to his go cart, while Cameron gives the squirrels nuts he found back in the kitchen, he tosses them away and land near Jo, Lightning, and Chef. They all run as all the squirrels go after them.

Cameron is the first to drive, while Scott tries to go as well, but his cart was missing the two front wheels. He uses Mike as a tow for him, and Zoey drives past them. Meanwhile, Jo and Lightning are now stuck in a prison chamber guarded by Fang the shark.

Nearby, Zoey is the first to tag the first land mark, she uses a heart and drives off to the next. Cameron had just passed her to tag it himself. When Scott and Mike arrive, Scott says he's going first. Cameron is still working on his design, and Mike tries to warn him that he doesn't need to be as detailed as what he was doing. Scott honks his horn repeatedly so Mike couldn't finish his sentence and goes back to the cart. Back at the prison cell, Jo and Lightning had come up with a plan to get out of the cell.

The camera is then back to Zoey who just tagged the second landmark and drives off, then Mike and Scott get there, but Scott uses Mike to check if it's safe, which it wasn't. Lighting had then finally pulled the bars apart on his cell door, Jo then pushes him out into Fang and leaves him. Lighnting then makes a deal with the shark to take him to Scott. While in the go cart, a message appears on the GPS from a dummy of Chris and a tape recording of his voice telling the campers to go to a fourth landmark. The camera then reveals it was Chef trying to get back at Chris for allowing the campers to steal his go carts.

Jo had finally caught up to Cameron, who just finished his tag of himself getting the million from Chris. Jo then uses her tag to cross out his tag and tells him it's a race not art school.

Zoey is then seen almost to the top of the totem, Scott uses Mike for a boost and throws his spray can at Zoey onto a ledge. Mike tries to help, but Scott rips off his shirt to get Vito. He then asks where Anne Maria was again, Scott agreed to show him where she was for a lift, leaving Zoey behind. Jo is then seen in the woods, with her car keep breaking, while Lightning passes her. Zoey couldn't hold on and lands on Cameron's cart allowing him to jump up the top. Chris then appears about to declare the winner, but everyone was gone, he then finds out that a fourth was added. He quickly blames it on Duncan and ride to the landmark.

At Mt. Chris, Vito asks where the "club" was where Anne Maria might be, Scott then knocks him out with an actual club, knocking him out. Zoey finally comes up to Mike telling them that their through, but realizes he was knocked out. In his subconscious, Mike finds himself with all four of his alternate personalities. They all gang up on him, but he retaliates and tells them that he's taking charge from now on. He gains control of his body and wakes up to Zoey. He then tells her all of his "characters" were because of his disorder and didn't want to look like a freak. Zoey then says she loves odd-balls and says that there is just more Mike to love. Scott and Lightning were the only ones to reach the top, but Lightning sprays with a giant lighting bolt first. Chris then says he didn't win because Duncan added this mark. Duncan then appears from behind a rock saying this wasn't his idea and blew up Mount Chrismore. Chris then says Scott was the winner.

At the elimination ceremony, Scott got to choose who was going home and chooses Mike. At the Hurl of Shame, Zoey comes up to Mike trying to say her last goodbye. Mike gives her a gold medal with his face on it, which she loves. They lean in for a goodbye kiss, but Chris interrupts them by hurling Mike.

General

 * The Mutant Maggots and the Toxic Rats merge in this episode.
 * Considering the number of contestants that made the merge, this is the latest merge of the series (but this is probably because of the small cast this season)
 * 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, and yet angry, 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 the first time one of Mike's alternate personalities (Chester) uses the confessional.
 * 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.
 * 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.

Continuity

 * This is the first 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 so her vote was the only one that counted.
 * 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.
 * This is the fifth time a couple's kiss is interrupted before they were separated. The other times were Gwen and Trent in Search and Do Not Destroy, Bridgette and Geoff in Hide and Be Sneaky, 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.
 * When Manitoba Smith is punching Mike along with Chester, Svetlana and Vito, he has a bag on his back. However, in a previous scene, where Manitoba ropes Mike, the bag is absent. Chester was also seen with a cane but not in the beginning.
