Some questions
So, was Desmond always asking confused questions because he can time travel as well and he's never quite sure if something important has changed in the other relative's lives? Or was that just oddball humor? Was it a sign that things have changed from his perspective that we're unaware of?
It looked like the rules of time travel were that you appear in a closet when you go back. Does that mean wherever you were in the original timeline at that moment, you appear to totally disappear right then to materialize in the closet? They show it working like that the first few times but then he just seems to be wherever he wants to be after that.
