I read about this fic ages ago but I forgot to bookmark it. Here's what I  remember:
Its a very dark fic. Dean, I  think blames Sam for everything that has happened to them. I don't  remember a lot more but I think the title was This Time or something.  Does it ring a bell? Also the banner had a picture of Heath Ledger. I  don't know if I'm mixing two fics up but if anyone knows which fic I'm  talking about please link me to it. Thank you!
