It's the function of people to ultimately fail expectations, after all. It's stupid to expect anyone to linger without being a turncoat or up and falling down dead. Equally stupid to think anyone else might understand the distant ache of remembering how much better hot cocoa could be when Alfred made it -- just the right amount of milk, with the really big marshmallow floating in the middle. Stupid little things that Aang understood yesterday. Whatever.
