Thank you so much for the link anon, that fic was... fascinating isn't the right word. It held me, though...

I might try a mini-fill. I was wondering, since the prompt was vague(which was good!) were you looking specifically for some Sally/Sherlock or just the two of them together in the Quiet Room, not necessarily having sex?
This concept is beyond words. I really want to try a fill but I might mess it up. Worth a try?
