[Supersonic]

I haven't seen this mentioned in any of the threads here but did anyone notice that the assassin who killed Nakamura was sliding their hand along the wall when they came out onto the roof, as if they might be blind?

Also wtf is up with the introductions to some episodes containing spoilers? Within 2 minutes of Season 2 I knew a bunch of things that were going to happen including the return of Sylar, and some things that still have not happened.
