So I brought his cell phone to his apartment to switch back. His apartment was impressive but troublesome. Everything was rebuilt and redecorated to look like the Land of the Lost. He had animatronic dinosaurs and kind of inauthentic-looking retro-70s jungle set designs. His roommate was a Sleestak or (I hope) just dressed like one.
The amount of effort it must have taken to do that was impressive and pathetic at once!
But I got my cell phone back!
