I'm looking for a fic that went AU sometime after the end of Season 6. Dean and Castiel's relationship is broken badly but they are forced to deal with it because of some hunt they are on where each step requires them to deal with their feelings. The only part I can really remember is that they had to stand in a hot spring together and talk about their feelings and Dean hated it (of course!). I know this is vague so thank for any help.
