Future Peter is kind of a dick, and the "god" stuff with nathan bugged me a little, and no way Suresh would bag a girl like Maya. Okay, that last one was just me hatin', but things are set up for sure. I hope claire doesn't become evil, I doubt that would happen because that would be too obvious. Peter and Nathan's mom is an awesome evil bitch, I love that character.
I hope Nathan actually reaches out to claire and tries to become a father to her as well, and it was great to see Nikki alive, but different, and maybe not even nikki. Whatever, its all good.
