I've always speculated that while in Abstergo, if Desmond ever tried to hide from the cameras in his room, the guards would come in and bust his head. And then I came across a prompt for Apple!time-travel shenanigans. My brain combined the two ideas somehow, which leads me to my prompt.

Before he gets very far with Altair's memories, Desmond tries to hide behind a towel while he takes a shower. When Vidic sends the guards in, Desmond has *mysteriously vanished*! Cut to the Rosa in Fiore, where Claudia has to deal with a wet, naked, and very confused Desmond who tries to trade this strange gold orb he has for pants.

BONUS: They don't have any men's clothes on hand.
