Two chairs of the same machine are located in Shark's Monitor Room. Buzby flips the machine's switch on two occasions. Aside from Fitz and Shark switching minds, the latter has Fitz wake up with his old memories from the show via flashbacks return to his own mind, and he has Shark's voice, for obvious reasons.
