Hi, so I read this fic a long time ago and now I can't find it. Basically Dean lives with John, and Sam with Mary. But when John dies, Dean has to go live with Mary, and he hasn't seen her or Sam since he was 4. Sam doesn't really recognise him. Dean and Castiel becomes good friends, and eventually get together. When Dean finally settles in, bad things happens to him. Alastair kidnaps Dean and tortures him, but Dean comes back. I don't remember what is was called, or who wrote it.
