I'm looking for an old story--gen and probably set in Season 1 or 2 (I don't remember any issues with John or Dean's deal in the story). It started out with Sam and Dean talking in a motel room--it was obvious Sam was ill/hurt (from a previous case maybe? I don't remember if they ever said) and Sam was playing with a dog they had found roaming around and who had just followed them. As the story progresses they have the motel owner's granddaughter (?) watch the dog while they are out and possibly give the dog to her at the end.
This was a case fic--the dog is really not a big part of it, but it is what I remember the most. The bad guy was a warlock (maybe) who was after Sam--seems like I remember him putting sigils on a magic cloth to trap Sam/his other victims.
What is really annoying is that at some point I had this story saved because I really liked it, but I have either lost it or not tagged it properly because I can't find it at all. And possibly I read it at FF.com. Thanks so much for your help!
