The Treasure Island of Dr. McLean

The teams wake up in the middle of the lake and are ordered by Chris to get back to the island, with the last team arriving set for punishment. During this part of the challenge, Mike purposely places Scott in a position for another encounter with Fang, who attacks him near, and then on, the Maggots' raft. Dakota fends off the shark as she begins a mutant transformation into a monster and then seeks friendship from Zoey. Meanwhile, Cameron tries to help Mike keep his secret under control. Scott reveals to have found the Chris Head of Invincibility, and asks Zoey to keep it a secret. At the end, after the Maggots lose the second challenge, finding a buried chest containing a past contestant and an eliminated contestant from the current season, Scott receives the votes to be sent home, but uses the Chris Head of Invincibility to stay in the game, and Dakota is eliminated instead. Gwen cameos, and Sam temporarily returns as part of the challenge.
