Eden wasn't a moron, though she clearly underestimated Sylar's abilities. When he saw the gun in her hand he said, "You know you can't hurt me with that" or something to that effect. She then shot herself in the head to prevent Sylar from taking on her powers.
Claire's father has always appeared suspicious to me and I don't feel he is trustworthy. The Haitian (what's his name?) may be very helpful, I am thinking. But then, that is what we are supposed to believe, perhaps?
Peter is such a good guy with an honest heart, and his brother is just AWFUL! He's puts Peter down all the time which makes me crazy. When is Nathan going to see the whole picture and realize Peter is not a slacker and a loser?
Oh, in last week's episode was Nathan's car crash which paralyzed his wife. He was suddenly lifted out of the car and hovering, so to speak, as the car crashed. That was 6 months prior to the present. I don't recall any explanation for that happening to him and he didn't discuss it with anybody. Was he aware of his powers at that time?
