Oh, I love this. I found this by clicking on the "supernatural/mythical" tag at sgagenrefinders and searching randomly through the requests that were there... and wow, am I glad I did. I love the idea of John with wings. He totally needs them. (Why yes, I am a superpower/supernatural nut, why do you ask? :P) Seriously, I love this. Angsty AND superpowered John... could it get any better? Possibly. But it would take a much longer fic. :) (Actually, that wasn't a hint... unless, you know, you get inspired. I certainly wouldn't be complaining.)
