So, this is a weird scene all around, and he couldn't begin to guess what's going on between Holmes and Watson. He'll have to come by soon, maybe catch Watson alone and have a chat. For now, though, he can't do anything except deal with Holmes and all his hesitant greeting; even his insult lacks its usual punch, and he sounds so... so nervous.

He's had a lot of time to think about this after he left Mrs. Hudson, after he had a talk with Mary and loitered around on Baker street for the past few hours. It's the wax figure of Watson that seems to settle it for him; this all has something to do with Watson's safety, he's sure of it. That's not to say Holmes maybe was an enormous prat about it all, but still.

"That's sweet, Holmes," he says wryly, but then his smile turns more serious. "It's good to have you back in London. And I'm not talking about my arrest record, before you try that."
