Bella was expecting to be slightly late to math class. This is not math class, but it seems like the sort of thing she ought to be later to math class in order to investigate. In she stalks, ready for something to jump out at her, wondering if she ought to pull a stake out of her bag.
"Okay. Well, if desensitization therapy is still in vogue in the thirtieth century and you feel like doing any of it while we are both still in this bar, I am in the background quietly amenable to patting you on the head."
"Man, I wish Sherlock were awake and within yelling distance of my door, but he's nocturnal and does not frequent my high school, so I cannot introduce you and see what he'd make of you."
"And if I went home with you to meet him there's always the chance that I would be unable to go home," he says. "Which is some degree of undesirable."
"You seem more relaxed about this undesirability than I imagine most people would be."
"Eh. I have a family, in a sense, but I'm not completely sure I will ever want to see any of them again. Or meet the ones I haven't."
"Reasonable, I suppose, it sounds like eighty percent high-octane drama."
"Is it in fact one hundred and sixty percent high-octane drama?"
"I have a pretty undramatic family life. I mean, except for the divorce, but I don't remember that."
"I was literally created to destroy my family. It makes things interesting."

"Roaming the wormhole nexus, confusing the intelligence agents sent to track my movements, trying to figure out what if anything I want to do with my life and whether or not I want it to involve any of my relatives."
"Why are there intelligence agents tracking your movements?"
"Because I was created to destroy my family and, through them, their planet. Barrayaran Imperial Security has an interest in knowing what I am up to."
"Well, isn't that just ducky." Pause. "I might be able to get ahold of my Watcher from where my door is, and get him to go wake up and transport Sherlock, if you want to meet him, but it'd be risky and I'd like to leave it to when I'm about ready to head out of the magic bar."
"Sure. It's between classes, the library door should be open, and my supernatural accuracy applies to paper airplanes."
Reasonably. If you are never going to return to your home world, or will only do so should conditions requiring the passage of time there be met, then time will pass.
"Does resolving not to leave until Giles hauls Sherlock here count?"
It is unlikely that merely resolving to stay put will meet the conditions.
"Damn. Well, the crypt isn't that far away."
"Your boyfriend lives in a crypt? Because he is a vampire, or for unrelated reasons?"
