Supernatural Fic -- if a body catch a body

My latest attempt at fanfiction. Both the title and the quote come from J. D. Salinger's The Catcher in the Rye, which I was rereading lately. This will, of course, continue my disturbing trend of taking widely respected modern literature and bastardizing it by associating it with my bad fanfic. I'm a little sorry.

Anyway, I keep picturing all these little kids playing some game in this big field of rye and all. Thousands of little kids, and nobody’s around — nobody big, I mean — except me. And I’m standing on the edge of some crazy cliff. What I have to do, I have to catch everybody if they start to go over the cliff — I mean if they’re running and they don’t look where they’re going I have to come out from somewhere and catch them. That’s all I’d do all day. I’d just be the catcher in the rye, and all. I know it’s crazy, but that’s the only thing I’d really like to be. I know it’s crazy. 
— J. D. Salinger
