TPTB know how to bring it on this show. Pushing all the right buttons doesn't begin to cover it. I enjoy it when they get to the point. We know what Sam's more afraid of than Alistair now. Wouldn't it have been nice if Nathan and Peter Petrelli could have "talked" like this?
Or, you know, just talked?
Have they spent more than five minutes together since season one? There was that hug in the police station before future Pete shot him. Then Nathan may have gotten mad, who knows? 
When The Levee Breaks
I can't wait. Dean and Sam--even when they're at each others' throats they bring it.
