I think the Peter/Claire chemistry (which is WAY up, even my mother noticed!) is so intense because their actors are dating, if I'm correct. And the Petrellis are somewhat messed up. I assume Nathan got the whole extra-children thing from his mama- that would sure explain a lot. Like extra children with random other characters runs in the family or something.

I love that Adam comes back. Or so I assume from Mama Petrelli's dream. Yay!

Quinto/Sylar is so hit-able. Even his Spock will probably be hit-able. And the world may never know why.
