Since Moffat often uses dancing as a metaphor for sex in Doctor Who (empty child/doctor dances, Girl in the Fireplace) I wonder what was really meant by Sherlock loving dancing when everyone thinks he doesn’t.

I was thinking about the sign of three. “I will solve your murder, but it will take John Watson to save your life.”

Major Scholto was the victim. Sherlock told him he was the one murdered (and nabbed the photographer).

John Watson was prepared to kick down the door.

But it was Sherlock that talked him down. Of course John would have done the actual doctoring, but this time, Sherlock did save the life.
