I couldn't stop laughing my fool head off when Sherlock had his little hissy fit at John telling him to "better yet, stop inflicting your opinions on the world" and when John says he's leaving Sherlock is like, "Where are you
going?"

Dammit, you're supposed to stay and fight with me when I'm having a tantrum.
Does Sherlock even call him "John" in any other incarnation of the characters?
