She is all over it at lunch.
"Okay, so, Transfig is just about the coolest thing," she says first thing to the Ravenclaws as soon as she sits at the table.
"I can, like, fake Ravenclaw. I can fake it really well and I don't think it's even going to be uncomfortable doing it for seven years. But I am more 'cunning' than 'wit' and more 'ambition' than 'literally anything else'."
It's not that funny, but when someone's so clearly out of control with laughter it's hard not to giggle with them!
Eventually he manages to calm down, with the exception of the occasional giggle. "It kinda is! Or, well, you know I have a peculiar sense of humour." Smirk. "Threatening the hat." Fit of giggles.
"Your secret's safe with me," he says, and morphs his mouth away to demonstrate. Then he's overtaken by another sudden fit of giggles and has to morph his mouth back. "Sorry, sorry, I'm okay now." He clears his throat. His eyes have become a clear gold, though.
"Huh. Cool." He morphs it into green, though, rather than his previous blue. "Feeling more like green. Aaaannnnyyyyway, let's talk some more about Miranda's dirty little secret. So I guess I'm actually more Ravenclaw than you, huh?"
"I like Ravenclaw more than the other two, but I wouldn't have left Hogwarts over it if the hat had decided to put me in Gryffindor or Hufflepuff. I do think Ravenclaw is the obvious second choice."
He nods. "Well now I'm feeling like you stole the title of Most Slytherin Hogwarts Student. What am I gonna be? Who am I even? What's leeeeeeeft?"
"More Slytherin than someone who threatened the Hat to get away from Slytherin? Weren't you just saying something along the lines of it not being a hard categorisation anyway and stuff?"
"It wasn't close for me, that doesn't mean it's close for everybody who does wind up in Slytherin! And I think wanting it would exemplify the House more, I don't know, cleanly."
"No, wanting it is probably more likely to mean you think you exemplify the House more cleanly. I'd be hard-pressed to vouch for the self-awareness of most members of my House. You could probably out-Slytherin a committee including all seventh—and sixth-year Slytherins if they were coached by the ghost of Salazar himself." He doesn't actually know that for a fact, but that's not stopping him from saying it anyway.
"What, because you like how my mind works? I think that's pushing it. You don't even know all those students."
"I'm pretty sure Slytherin's rep wouldn't be this bad if we had had two consecutive years of competent Slytherins at some point in the recent past. The Proper Slytherin Behaviour speech was given by a seventh-year! And the others were nodding along sagely as if we were being imparted wisdom handed down from Merlin himself! Also yes, I very much like how your mind works, it's a very good mind."
"There would only have to be one to beat me in a Slytherining fight, and 'keep your head down' isn't necessarily a bad strategy if you can't leave the House or the country."
"Terribly good points, you beat me once again, I can't compete with your Slytherin might."
