An unrelated question...Do we know where Sylar got his ability to freeze things? For some reason, I don't remember us seeing him steal that from anyone, but it's appeared in a couple different episodes now, most recently when he broke Hiro's sword.

That's probably my only pet peave, when Sylar or Peter have powers apparently appear out of nowhere and we have no indication of how they gained them. That said, I may just not be recalling where he got that.
