Sam/Dean fic with evil!Sam

[fourthofjuly96]

Hey, I'm looking for a story I read ages ago but I don't really remember any details from it other than it was evil!Sam and he had Dean in a hotel room. At one point I think he left Dean in a closet for a while and at another I know he just left him to sit on a bench for a day to see if he would run away and he didn't. As far as I remember it wasn't too sexual but more creepy. If anyone knows of it based off of these tiny details thanks in advance haha

(Any other lesser known fic recs with evil!Sam are also appreciated, I've read most of the big ones)
