Yeah, he got the ability and now he's stuck in a coma. Personally I don't much care for the direction his character is taking this season. On some level I can understand what they were trying to do - in order to save the world he has to become a villain - but if anything that made him more of an idiot. Now he's slicing heads left and right like some addict on speed. If anything that just made him worse. I miss the Peter from S1 where he was trying to get out of Nathan's shadow, be more than just a nurse and save the world, etc.
Why must Sylar be a Petrelli anyway? To me, that just seemed like the writers using a stock cliche to give his character an unnecessary "development". (Not to mention ruins all those Petlar fics I read ) The final scene in the car, with HRG, Claire and Sylar, almost made me intrigued by the potential for a Sylar-Claire match up.
Also, what happened to his super hearing? While he was waiting by the car, and HRG was wanting vortex-guy to kill him, he seemed unable to hear them. Whereas we know from his Road Trip of Awesome with Mohinder, that's not the case.
Papa Petrelli is a completely unnecessary addition to the cast. As is the sudden overpowering of Nightmare Man.
Mohinder is dull already, but at least he shut Maya up. That's a plus.
