Okay I thought that was a pretty freakin amazing episode!!
Firstly, Takezo/Adam. Clearly Hiros betrayal left a scar, but that cant possibly be his soul motivation. I think it started him down a path of using his powers for personal gain and hes quickly developed himself into a 'Magneto'. Thanks to Parkman, he no longer has Maury (Loved how Parkman pwnt his pappy!) but hes set his sights on Peter now. Some how Nathan has to get their in time, to prevent Peter from becoming a pawn.
West is the creepiest guy. And it bugs me so much how whenever he acts creepy, he and Claire just kissy kissy, and shes all happy again.
Oh Mohinder....are you doing the right thing. So confusing!!

No twins!! But sadly that means no Sylar either. What happens when Sylar and Takezo/Adam meet. It sounds more or less like Adam is Magneto, and just wants muta-er heroes to be able to live freely and all. But Sylar wants all their powers unto himself, so he doesnt really mesh properly.
