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.
Willow is not as oblivious as Sadde, but she's about as tactless. "Hey Karen, are you okay?"
Sadde looks between both of them, somewhat bemused, then shrugs herself and finishes drinking and eating her breakfast.
Eventually even Willow finishes eating. "I'm so excited about Charms! I wonder what we'll learn."
"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.
"It's from this series of movies—er, do you guys have movies?" she asks as Willow continues doing her swooshes and zwooooms.
Willow makes a zwwwooom! motion and sound between them to illustrate.
"Kinda like that," Sadde says. "Also next year they're gonna release a prequel movie to this trilogy."
Willow stops her noises and motions to stare at Sadde. "You what?!"
"Sorry!" she laughs. "Anyway, yeah, they're usually yea long and there's this metal handle and when it's turned off it's just a handle but when it's turned on the blade is made of light or something and it's all shiny and stuff, and it can cut most things but not other light sabers so there are light saber fights."
Willow deems this explanation satisfactory and starts pretending to be duelling someone with her invisible light saber again.
Sadde smiles in a way that might suggest she wasn't that oblivious about Karen's earlier discomfort, and nods. "It's kinda weird, yeah, but kinda fun, too." She watches Willow savage three simultaneous enemies and laughs.
"Movies are pretty neat," Miranda tells Karen. "Maybe sometime if we hang out on a school break you can see one."
