Mohinder's ability seems all over the place. Is he super strong, super fast, super flexible? All three seems like a jump the shark moment. Maya, ick. Can't stand her.
Did Mama Pertelli mean she is Sylar's biological mother? If so, wow. Interesting twist, since only Peter has enough firepower to go up against Sylar. Brother verses brother.
Is Nathan going crazy? He now sees dead people? I don't think Linderman is alive or healed Nathan. I believe Peter healed him.
Hiro's story looks interesting, so does Matt's and Claire's. I feel so bad for Claire, though.

Did anyone else think of Halloween when Claire was in the closet?

I'm over the Nikki/Jessica/Tracy story. They should have just killed her off. No, I don't think a different personality has a different power. Jessica and Nikki had the same power--super strength. I also think the reporter guy--the one who played Greatest American Hero--will be back. He'll have some kind of power. They lingered over the ice and water going down the drain for too long to not be important. Micah and his cousin aren't on the show anymore. I don't know if they'll explain this or not.
Peter's journey looks to be the most interesting again. Of course he changed things by coming back, but the future isn't set in stone.
I wonder how he put present Peter in Jesse. And does present Peter have his powers or Jesse's?
Love the Elle character. and I can't wait to see how we go from good Ando to the one in Hiro's future.
