Matt was wonderful in the ep. I'll be surprised if the kill Hiro. It seems like he's too well liked, and there could be a bad reaction to his death. Any other character could die (even my fave, Matt) and the fans would deal with it, I think, but Hiro is like the adorable, idealistic kid everyone likes. I think its more likely Matt, Nathan or maybe Ando will die.

The whole Sylar and his mommy thing freaked me out, but that's 'cause the movie Psycho freaks me to no end.
