"Throwing the game requires more effort, and is therefore more interesting," she explains.
"Huh. I'll see about curbing that. Or at least staring at misleading random cards."
"Sherlock, do you even sleep?"
Bell may know Sherlock well enough by now to detect an evasion. Or not.
"Less than I do, such that you're not groggy when I'm waking up or yawning when I'm falling asleep," clarifies Bell. "That kind of occasionally? Or more like a not-since-I-came-on-the-train occasionally?"
"I can't see you when I'm asleep," Bell points out. "Would it help if I re-oriented so I wound up with my head under your bed? Or under the bed entirely? I don't want you kept up at night on my account, whether or not Milliways is being obnoxious."
"'Anyone' includes an open window with no one on the other side. People sleeping under my bed likewise qualify. I expect I will survive until we get home."
(District Four does have cats. Big, mean ratters. But still cats, and still they nap.)
"Okay, if you say so. You know more about your tolerances than I do."
"Still, I hope Tony can get the door to work soon. I... am now sort of worried that it can tell he's trying on my behalf, and whatever makes it stay away from me so long is contagious like that. Do you suppose that's possible?"
"Maybe next time he should open the door while pretending it's for you, regardless."
"I'm always afraid I'll never see it again. I mean, I act like I'm not. I leave things there. I walk out the door, I never waited until I was so hungry I had to crawl. But I'm always afraid of it. And once I made it onto the train I wasn't, for a bit, because I wasn't going to be the one trying, and now I am again."
(Bell is quite willing to discuss her displeasure with aspects of the establishment when she is not actually in it.)
