Watched A game of Shadows today
headcanon time: Mary and Mycroft are totally BFF now and they’re going to have cool adventures of their own while Sherlock and John do their stuff.
Also, if there’s a third film and Mary dies, I’ll hate Guy Ritchie for ever because she is the coolest person ever.
(Mycroft is the second coolest person ever. Mortiarty is the third, Simza is fourth, Moran is fifth, Sherlock and John are number six when together)
