I'm glad Nathan's story is finally "going somewhere." Although he STILL never bothered to say, "You shot me, Pete! You son of a bitch!" But I guess they're even, now, as Peter saved his life.
That's a little too much to expect from the Heroes' writers. I realize that not a great deal of time is supposed to have passed since the season began, but by keeping the Petrelli brothers separated for so long onscreen, the writers have missed the opportunity to really connect the dots in a satisfying way with the brothers. If groundwork had been laid showing Nathan having any sort of plausible emotional reaction to Peter shooting him (instead of "finding God") I could buy his behavior now as some sort of PTSD/irrational emotional response to losing faith and trust in his brother, who was supposed to mean the world to him until the end of last season. (Remember the love fest when Peter finally found his brains about Adam and the virus all because he trusted Nathan?) Having a family member shoot you, presumably one with whom you're very close, would be traumatic for anybody.
But the writers didn't lay that groundwork. Nathan's sudden contempt for Peter and the other powered people seems too much. He's going to have them hunt and lock up Peter and Claire, his own daughter?
Excellent point. Emotional turmoil is never fleshed out on this show. Characters go to one personality to another and back again whenever the writers feel like it. It really is a mess.
Perhaps Nathan wants them brought all together so he can get them to work together and save the world.
