"—more or less intermittently," she starts explaining. "Which, you see, conflicts a bit with the gender segregation thingamabob," she says, and takes a bite of her muffin.

"Last night I was a boy, so I slept in the boys dorm."

"Is there some reason you cannot continue to do that? While, of course, not alarming your roommates with - nocturnal femininity."

"Well, a few? I mean, I don't particularly care whether I sleep in the boys' dorm or the girls' dorm, though I do care some about having to always go to bed as a boy, but I can't exactly," she gestures at herself, "hide that I'm not a boy 100% of the time. So even if I did in fact always go to bed as a boy all the other boys would know that I was not, in fact, always a boy, and many times had not been a boy all day or for the previous few days, bedtime excepted." Om nom muffin.

Slughorn sighs. "Well, if being a boy at the times you are in the boy's room does not suffice for the other boys, send them to me," he says.

She shrugs, swallows the bit of muffin in her mouth, and says, "Alright. Also, question, am I allowed to eat at a table other than Slytherin's?"

"There's not formally a rule against it, but if the other students who belong to the table's House want you to leave you better had."

She nods, thanks him, and goes check if there's space for her with Miranda and Willow.

Lots. Miranda scoots so Sadde can sit between her and Willow. Karen's on Miranda's other side, and looks nervous about the Slytherin but doesn't say anything.

"Hi! Your girl self is really pretty!" Willow says during a foodless second. The foodless second ends.

"Thanks!" Sadde says brightly as she takes a seat. "Hello, there, I'm Sadde," she greets the other girl, then looks for non-muffin food now that she has the time to pay attention to it.

"This is Karen," Miranda says, when Karen doesn't introduce herself. Miranda is almost finished eating and Karen appears to have been satisfied with most of a cantaloupe slice and some toast.

Sadde decides she's not particularly hungry and just serves herself some hot chocolate and some toast. "Nice to meet you!" she tells Karen, apparently oblivious to the girl's discomfort. "So I guess we'll have Charms together," she adds conversationally.

"Yup. I'm looking forward to it."

Willow is not as oblivious as Sadde, but she's about as tactless. "Hey Karen, are you okay?"

"I'm fine."

Miranda sighs slightly and polishes off her hash browns.

Eventually even Willow finishes eating. "I'm so excited about Charms! I wonder what we'll learn."

"Probably the stuff from the books," Sadde points out reasonably.

"He might not go in order, though," says Miranda, shouldering her bag.

Willow grabs her own bag and pretends she's holding an invisible wand. "Maybe they'll teach us how to turn our wands into light sabers!" she says, and starts swinging her invisible wand-slash-light-saber around, producing accompanying sound effects with her mouth.

Sadde giggles.

"I don't think that's a real spell," says Miranda.
