I've just been asked which fic is the one that's sort of a sequel to So You Want To Transfigure Yourself a Rock Band, where Remus and Sirius are living together, and Remus thinks Sirius is cheating on him but it turns out he's just going to disco clubs. Does anybody recall this? I didn't write this one (uh, i'm pretty sure).
You know I don't even have a Remus/Sirius icon any more? Lol, I have to use the glam one.
ETA: GOT IT. Scriblix is a genius. It's The Death of Glitter, part of the B's original Glitterverse fic, although a late chapter.
