I really wasn't sure about
Someone You Might Have Been when I started reading it but before I knew what was happening I'd been totally sucked in. It's a good fic in itself but what is even more hella awesome is
this vid that was made to go with it. Don't watch the vid until you've read the fic as it pretty much gives you the whole plot and there are some twists you don't want to be spoiled for
And I only just realised that this fic was written by the same person who wrote Bulletproof which I recced yesterday. Wow. And she writes Dean/Castiel. Must check some of those out soon.
