Hi, I'm looking for a fic in which Castiel makes a deal with crowley: he offers up his grace to Crowley , in return Crowley gets Sam out of Hell and promises that Sam or Dean (or any other hunter, I believe) can no longer talk with demons. Dean is at Lisa when he suddenly sees Sam in the distance and then suddenly starts trashing, so Sam rushes in. Dean first doesn't believe it really is his brother but Sam can make him realise. I believe that afterwards, Dean notices that Castiel's handprint has dissapeared, making him worried. But Castiel doesn't respond (I think the idea was that Castiel should have died after giving away his grace) They try to contact demons to interrogate but they can't find any nor can Bobby or any other hunters (I think)

I can't say for sure whether this story has a pairing but I read a lot of Dean/castiel so it could have them, I'm sorry I can't be more specific.

Thank you very much!
