I really do think Claire should have maybe been a season 1 only character. Save the world, save the cheerleader. She's running out of possibilities. Maybe have her a guest star to come back periodically like future self...
yeah, i really hope that this whole "one that brings the light" or whatever the quote from Nakamura was on the video does not turn out to be her.
Yep. I'm sorry. Yeah she's cute but really, she has no offensive abilities. What she going to do? Smother someone?
Adam has the exact same powers as Claire and he was the big bad last season. Of course Adam has 400 years of experience and intelligence, inside knowledge of the Company, and is damn good with a sword...

Just having Claire take some karate lessions would go a long way.

But I doubt it will last.
They come from two different worlds - Dexter's cosmos is carefully constructed so that the characters stay consistent and never are dragged here and there just because the plot demands it. Sylar lives in a crueler universe, where the writers are sloppier and decide to tame him down with a new Mommy because they want it that way, not because it makes any damn sense at all. If the Dexter writers ever tried something that cheeseball, I would be massively disappointed, but to see it on Heroes is far from unexpected.
