My guess is something to do with the shapeshifting, and his inability to control various aspects of himself. Perhaps his "sweet spot" wasn't where Danko thought it was...
[spoiler]Well, I was sort of right. It looks like he deliberately moved it.[/spoiler]
a little claire blood should fix that one issue they developed..
[spoiler]Yeah, I wasn't really upset when Nathan was killed, as I figured people will die occasionally.
Then they came up with that stupid suggestion to have Sylar live on as Nathan and I was pissed.
Then, after the show was over, I couldn't help but wonder why they didn't just use some of Claire's blood (good
fridge logic there
).
That's the only thing that bugged me about it. Noah
knows about the qualities of Claire's blood, having experienced it first hand (or is he anaware of how he was saved?). It just seems they have a much better solution, and they pick the stupid one that still leaves Nathan dead and Sylar alive.
Gah!!![/spoiler]
