Did anyone watch the season 3 finale of Heroes?
Yes, Nathan is dead because Sylar killed him. It won’t be the end of the character though, because Sylar had his memory wiped by Matt, and now thinks he is Nathan (and has shapeshifted into Nathan). If Sylar remembers who he really is and changes back, it could be the end for Nathan, but everything will unfold in series 4 next year. It’s not the end for Adrian Pasdar (Nathan) or Zachary Quinto (Sylar) as they are both involved with the next season, so we’ll see what happens 🙂 The body of the original shapeshifter (who was killed in Sylar’s form) was burned, to make it look like Sylar was dead to everyone else, but he isn’t. It’s kinda complicated, but I hope that made sense!
