I'm still of the impression they are one and the same. I don't really see how good of a guy he can be when he killed Chandra. Although I did just find something interesting on IMDB while I was looking up Chandra's name. They list Sean Bean as "Paul Sylar" in three episodes. Of course we all know how relable IMDB can be. Considering I sure as heck didn't see him in "Better Halves" I'm writting it off as a hoax.
