"Tell me, how badly did your real brother hurt you that you’re here looking for comfort from a serial killer?”

I love this line!
It's half-canon because Peter always looked up to Nathan; always respected him. Well, at least in the earlier seasons he did. d:
Now, the non-canon half of that line -- I love how Peter was seeking comfort from Sylar.

Man, there are seriously not enough Peter/Sylar fics, whether it's slash or gen -- there's not nearly enough. ):

Great one shot, I enjoyed it very much! ^^
