The tiger painting on the wall in Andrew Scott's episode of Dates (1x08) made me think of MorMor, so now I'm thinking that Christian's wife could be Moran. You know, I did have a headcanon of Jim regularly going out and picking up people for sexy times, but the idea that he could go via a dating site is new. Gah, I want a MorMor fic about that. And Sebby is actually cool with Jim having sex with other people (or there's no sexual/romantic MorMor going on) - Seb just plays the cheated-on significant other to help Jim get rid of the dates. I should check sherlockbbc_fic, maybe it was already prompted or even filled.
