Yeah, it's the day after, **** the spoilers. My twisted view on last nights episode goes a little something like this.
Peter is sick due to the blood loss from his tussle/fall with Syler. Claire's healing power brought him back to life, but there wasn't enough proximity/time spent together for all of his blood to regenerate. You'll notice when he's talking with Claire he isn't sick. But then at the end of the show I'd guess he passes out due to lack of blood to his mutated brain.
And I think that Sylar figured out that he couldn't do anything to the glass inside the room, so he focused his TK on Eden instead.
Hiro gets a little more annoying to me as each week goes by. I'm still rooting for Nathan for some strange reason, and was equally impressed by Isaac finally being able to use his power without the help of those evil, nasty, life threatening drugs.
Are you sure it's only off for four weeks, Surrep?
