apparently he got Eden's DNA from her busted-open head---from the bullet-wound.
Edit: He's killed all of the ones that he stole from, so Eden killing herself wasn't thwarting him, though she didn't know it. What if he somehow acquired super-smart-girl's blood-clot problem also, and it is what causes the radiation-power's control loss, which blows up NY? End EDIT
Also, Sylar hasn't seen ALL of the list, necessarily. He doesn't have Parkman's thought-hearing. Suresh didn't ever show him the list, I don't think.
Parkman's wife is pregnant with the other cop's baby, not his. OR, merely being able to HEAR the thoughts of others, Parkman made an association in his own mund about who the guy---seemed genuinely supportive about the detective's test, and all---was thinking at, and decked him for no reason. When he "listened" to his wife, she thought "He knows..." and she could have been merely thinking about the baby, and had been anxious about how to tell him, with him being so bummed out, recently.
Mohinder was suddenly worried about them finding a decapitated Sylar in his apartment? That's the only reason I can think of that he should have let the crazyman live after all that. He'd already tried to shoot him. Maybe he was so freaked out by Peter's "death" that he just had to get out, taking Peter's body with to give to his next of kin. But it does make more sense if you think two things; he doesn't know how long Sylar is gonna be out, and, he doesn't realize that Peter is "dead". It would make sense, then, for him to not worry about taking Sylar out permanently, because he would know that he as a normal man had very little chance of winning, and for all he knew, Peter could only be unconscious, leaving him helpless and harvestable by Sylar, should he not move him. In the car, he realizes Peter is dead, and takes him to the Petrellis' house.
Anybody that thinks Nathan is going to let Linderman sacrifice Peter in five years ought to think again. He will formulate a plan and thwart his brother's death.
The radiation is going to blow, as scheduled, but it will be Sylar or Ted, not Peter.
Did anybody see in the previews, where Peter has D.L.'s phasing ability? How much you want to bet that he has Jessica's power(s), too. Cool to see more of what he can become.
Can't think of anything else, right now, so ...beh.
