I refuse to believe he's dead!!! Nope, in denial. He could have let go of Peter & flown away. Peter'd survive that. HE IS STILL ALIVE DAMNIT! Oh, Nathan.

I was thinking that Peter got the visions from Charles too, but you're right. He did get his first one before he started working for him. Maybe from his Dad, then? Maybe that's why the dad killed himself? Because he couldn't take the visions anymore?
