So, the new delicious sucks, yes? I really want to reread this fanfic I found a couple months ago, but I can't find it! The story goes like this:

Castiel goes to Hell to stop the apocalypse. He has a few minutes to say good-bye to Dean and Sam, but the guys are tired from a hunt and Dean won't listen when Cas tries to explain. A few years later, the guys get a call from Missouri about weird stuff going on at a hospital. Turns out it's Cas, rescued from Hell by Crowley. They take Cas back to Bobby's house and let him recover. Cas loses his voice, so everyone learns sign language, and eventually Cas joins Dean and Sam on a hunt.

I hope someone recognises this. Thank you in advance!
