His Name Literally Opens Doors

Sherlock's latest case -- for reasons not quite clear to John -- requires them to sneak into another top-secret military base. Sherlock is ready with Mycroft's stolen ID, but he hadn't counted on his husband being quite so well-known in the military. John is all kinds of BAMF.

Sherlock finally learns the story behind John's shoulder wound (and it is as insane as any Mad Doc story he's heard so far), and Mycroft learns just who his baby brother married.

All in all, this day is getting saved to Sherlock's mind palace as one of the most glorious days of his life.
