I'm the vidder... *grins*

Notes from Author: Written for spn_reversebang for this original vid prompt (http://www.4shared.com/video/tGl5SySf/Vigilante-Answers_2.html) by artist zenamydog. Warnings for violence and strong language. Casefic set in season 6, but AU after 5.22 so no spoilers for season 6.

Summary: Sam's returned; Dean isn't asking too many questions. They're just managing to put themselves back together again when Castiel asks them for a favor.

Every night for a year he’s watched his brother fall, in every sense of the word, and every morning he’s woken to a world that’s the wrong shape for him. (http://electricalgwen.livejournal.com/89425.html)
