This was really, really wonderful. I just adore all the identity complexities and the potential of the whole Sylar!Nathan situation in the show, and I think you've explored it in a way that really delves into and respects Nathan's psyche as being there while still acknowledging that he's working through Sylar's mind and body. I lovelovelove stuff like that, and this fic totally hit me in all the good places. :> Awesome!
