Sylar harbors a grudge against Noah Bennet, apparently. He goes out of his way to make the man's life misery - and rather cleverly succeeds. Danko is helping him in a few places, though - perhaps to protect his own hide.
In the meanwhile, Matt is on a mission to teach Danko a meaning of pain. Misery surely loves company. Matt goes pretty far, but in the end, it is nice to see he has some reason left in himself. Also, with Hiro and Ando bringing him good news and new hope, perhaps it will be time for him to step out of the circle of pain and loss. (Yay for the Stop and Go Baby. Also, gotta love the faces Ando kept pulling.)
The ending with the Petrelli family seemed hurried - a lot. Perhaps in the next episode they will explain what the digging-out-corpses is all about, and what is the big secret Angela is now prepared to share with his family.
Nice to see Peter and Nathan together again. "Let him vent." Awesome!
