Peter's power is to leech others powers how can he be having pre-cognitive dreams if he wasn't next to someone with the same ability. As to his sickness, that is a mystery I was agreeing with Rhoq in that he had internal damage and didn't fully heal, but then he met Claire again and still didn't heal.
Also who says her dad has power? If he did why didn't the Indian dude have him on the list? He had everyone else, he even called Claire's dad if his list is incomplete it is also somewhat irrelevant because it would also mean that not everyone on it has powers.
The Sylar/Peter fight would be an interesting one, because while Sylar was trying to kill Peter he would be leeching his powers and fighting him with the same ones he's trying to kill Peter with. :: Drool :: Let's just hope they don't CGI it.
Eden's power was the best, which makes you wonder why it didn't work against Sylar, also I believe it is the Hatian who cancels out power, otherwise why did they show him when the mind reading cop was deliberating with the FBI chick (he's probably going to end up in bed with) about why he couldn't use his powers.
Too bad Hiro's gf couldn't survive she was hot, not in the classical sense but I was strangely drawn to her. And her powers were interesting because they mimick my real life
.
Claire's dad definitely works for the government, he has too much available to him for it to be someone else, unless it's that dude who corrupted the Patrelli's dad and is working on flyguy atm and bought that painting too. that would explain a few things.
