There's a WIP about non-conventional Brian Justin relationship that I also liked very much. Though it is WIP, it feels like it is meant to be that way, an open ending, you know.

"Stockholm Syndrome" by themagichour.
It can be found in "DL More Lost Fics Here".

N.B. Watch out for the correct author. There're 2 different stories named "Stockholm Syndrome" there by 2 different authors.
