Already did those first two, soooo… 

P - Invent a random AU for any fandom (we always need more ideas)
Sherlock’s a chem teacher; Lestrade’s a football coach. John Watson is one of their students, and sticks up for Sherlock when some of the other kids try and bully him for being a little unique. Moriarty sees them (Sherlock & Greg) kissing after school and informs the parents who heinously throw a fit because they’re assholes. (Oh, wait… I’m writing that, aren’t I?)

Q - A ship you’ve abandoned and why
For bbc!Sherlock, Johnlock. I don’t ship it. I totally get that they’re soulmates, in a way — but I don’t ship them sexually. For ACD!verse, and Ritchie!Holmes, though. HNNNNNNNNNG.
