I had that "Peter is channeling Sylar" thought myself...glad to know I'm not crazy. Or, if I am crazy, at least I'm not the only one. :P

Also, all the talk about Peter and Sylar being "two sides of the same coin" and all that has really got me thinking...could they be related? Maybe Sylar is the result of an affair that Papa Petrelli had? I could be reaching here, but I think that'd be awesome. Not to mention all angsty and for Peter and Nathan...finding out they have a half-brother...and he's a serial killer!
