"Best of luck to our respective endeavours, I guess," she says, feeding her book into the purse thing.
Miranda sighs.
"I'm not actually up to much of anything. I'm eleven. I'm trying to learn enough stuff and know what I'm doing enough that I can be up to things really effectively later. But you kept making a huge deal about it and it bugged me so I bugged you back."
She walks over to a wall and bangs her forehead against it once. Not strongly or loudly or anything, just for effect.
"Oh, no, not at all," she says, turning to look at Miranda. "I yield. I have been defeated. You bested me. You have won. That was the single best prank ever oh my god how did I not see that one coming!"
She throws her hands up in the air. "Seriously! It has been eating away at me for months!"
"I would probably have fessed up sooner if I'd known you were going to get all serious about how much I trusted you."
"Well I'm a Slytherin of course I'm all serious about how much people trust me!"
"It's a thing! You know, network of contacts, bonds of mutual trust, rankings of what I can trust each person with, et cetera."
"Wow, generations of Slytherins have been crippled by You-Know-Who in a key asset, then."
"Most Slytherins have a very us vs. them thing, their 'network of contacts' is really only other Slytherins and to get even to the lowest rank of trust you have to also be a Slytherin. They do not know how to use their assets."
"It seems like when they had a functional reputation they must have at least occasionally noticed that there are seventy-five percent of people in other Houses, and no Slytherins at all outside the country..."
She shakes her head. "Seriously. My conspiracy of firsties will go through its opposition like a hot knife through butter!"
"I wonder if any of the other houses are missing key aspects of their repertoire."
"Hmm... well, you're a Ravenclaw, do you think eagles are missing anything?"
