In response to the Daphne and Ando thing, I think the writer sort of wrote themselves into a hole with that story line and giving Ando the power of time travel was just too easy and unrealistic so they had to come up with something different. Also Matt said something about Einstein's theory of relativity that if you could travel faster than the speed of light you could bend time and therefore travel through time so that was the validation for Daphne to be able to go back in time, though I agree you would think the combination of their powers would move them forward through time not back.
I had the same though about the president being African American
I can't believe what Nathan wants to do! I mean he is one of them too. So now he's just going to pretend he doesn't have a power and round them all up like criminals and put them in a jail like place. When did Nathan become such an extremist? He was also power hungry, but he still had a concept of right and wrong and wanted to do good for the people. Now he's just and extremist. Can he honestly believe all of the people in that file are a threat? Hiro, Parkman, Micah? Yeah there are some "special" people who are better locked up, but it seems like all Nathan wants now is to lock up all the original "special" people so they can't get in his way and he can start over and create his army with those marines.
