All in all a solid ending, and I'm looking forward to the next volume. A few things that didn't quite add up though. There's no reason for Nathan to fly away with Peter and ultimately kill himself, as Peter can obviously fly for himself. Also, DL and Parkman managed to both live an extremely long time after being shot (multiple times in Parkman's case) in the chest and/or stomach. There's no excuse for Hiro not finishing off Sylar, but now that he's left alive it leads us to think that Sylar will be a major factor in the future in addition to the new villain that Molly told us about earlier. My biggest problem with the final chapter was the anti-climatic fight between Peter and Sylar. This fight was built up so much in the Five Years Later episode, and it was way to quick and ended too suddenly. But something tells me we'll see the real fight in another four years since Sylar is still alive...
