whut happened at the fire escape is purposely left ambiguous, however there's a REASON why joe, whom ORIGINALLY wanted to learn french ends up in china instead and why his boss (who was from the future) KNEW he was going to go to china... it was clear this was done before!
Exactly, so that would also explain why Jeff Daniels (Dumb and Dumber) also knew:
He was hiding his friend because again like you said, he knew Young Joe's future already. I love that scene cause Young Joe couldn't even front on him, he did know the future. But he needed that code to get into the floor.This is also the reason they went to Young Joe's house when they were looking for his friend. They knew where he would go already.
