I don't watch Elementary but apparently in it Moriarty was a huge oil painting of Watson. I'd like BBC Moriarty to have the same, of John. It's in his bedroom, he looks at it every day - why? What happens when Sherlock and John find it? It's up to you.

If there's Moriarty/John I'd prefer it be one sided on Moriarty's side. Non con is fine, all other pairings also fine though I prefer John/Sherlock.
