Holmes has no idea what he's gotten himself into. Absolutely no idea.

"Duly noted," he replies after a pause, even though it's not duly noted or even necessarily understood, because when he deigns himself to play a role, it's with a purpose, generally for a case - and though that's often, and, yes, rather fun, he doesn't see much for her reason now.

He tries to remember what being a child is like. He recalls a pirate hat he had to be heartily bribed to remove.
