He said it as Nathan, then soon after shifted back into Sylar. I just watched it a couple of days ago.In "Five Years Gone" from Season 1, when Sylar and Peter duel it out fire vs. ice, Sylar says something like, "it's brother versus brother". Did he say this still disguised as Nathan or did he actually look like Sylar?
He didn't. Because Peter awnsers by saying:"My brother can't walk trough walls, who are you?". I really hope Mrs. Petrelli is just trying to manipulate Sylar and that she's not really his mother. She probably knows he killed his "real" mother while he was just trying to please her.
and if they are brothers, are they half brothers? And if so, whose Sylar's dad?
That's so hot. It would be even hotter if Hiro found out that he was actually the product of the affair between Angela and Kaito, as well. Inbred superheroes are the best kind!Hiro, he traveled back in time to 'tap that ass'.
Probably stupid Sylar.
