Well, the jig is up. If her House mates had any doubts about Sadde, they're gone.
...kinda. She's still young enough and androgynous enough that most of them think it's just a matter of changing her hair a bit and maybe some makeup and differently cut robes. It's not a belief that stands a whole lot of scrutiny, but given that most Slytherins give her a fairly wide berth, there's not actually been a whole lot of scrutiny.
She did find the Hufflepuff boy she spooked and tell him about it and offer to help him with his Potions homework. He was quite bewildered and suspicious because Slytherin so he didn't accept her help, but she told him to watch who she hangs out with so that he'd see she's Not Like Other Slytherins, and eventually he agreed, unable to see any way this could be a cunning plot. Which just goes to show that some people really couldn't be Slytherins.
Presently, it's Sunday, and Sadde would really like to talk to a certain Hat, which means she needs to talk to a certain Headmistress, and she suspects the most likely place she'll find her is the Head Table, at one of the meals. Breakfast is the first of those! Is McGonagall there?
"...fffffiiiiine. I guess you can keep your 'free will' and 'agency,'" she says, with air quotes.
And that evening Miranda joins Sadde to visit McGonagall's office, Sadde having received a note at lunch that the password is currently "biscuit".
"That's a cute password," Sadde comments to the Headmistress when she walks in.
"Well, basically, I want to fix Slytherin's reputation and make it so the Hat doesn't just send all evil kids and kids who don't care anyway to the House. Cunning and ambition do not mean evil, and evidently neither do they mean hate for muggles," she says, gesturing at herself.
"She also suggested better internal policing, and I'm not sure how I'd do that but your help and probably Slughorn's would be good. Prefects, maybe? And also the other very good idea she had was talking to the Hat, maybe it'd be able to help, or something."
Well, more like the fact that those are things that might call for disciplinary action slipped her mind.
Until she remembers. "Oh! Er. Maybe?"
"You might have to actually decide if you want Slytherin policed or not, Sadde," Miranda points out.
She sighs. "Well, I mean, in theory I do, but like, it feels like the standard methods aren't actually working? Unless internal policing has been extremely lax these past few years, but Professor Slughorn doesn't look like—well, I mean, he's fun and boisterous and stuff, but he looks like the kind of person who takes serious things seriously?"
"Professor Slughorn was brought out of retirement a few years ago," McGonagall says. "Prior to that time the head of house was Professor Snape, who did not devote very much attention to such affairs. So there may be some lingering effects from that, although you are correct that Professor Slughorn takes a serious approach to serious matters."
"Hm. In that case, there's this boy called Nyle Arens who jinxed me the other day, Professor Spukhafte might tell you about what happened, and he also punched me and flung me against a wall. This last part was in revenge, though, because I replaced all his underwear with girls' underwear, which I did because of the jinxing. So I guess both of us need disciplinary action?"
"Wouldn't it be funny if this was enough to make them get in line?" she giggles. "Anyway, can I talk to the hat? Or did the underwear thing cross some line?"
I bet. So, I dunno how much you know about what goes on in the world outside, in fact I'd love to ask you all sorts of questions about you later, but now mostly I wanted to see if you could think of ways to help me help Slytherin.
Well, yeah, sure, I imagined something like that would happen already, but surely there's some way to help now? I expect you can't tell me personal stuff about the students, and I wouldn't really want to know them anyway, but maybe you could give me some tips? I was thinking about uniting the first years and having us become an actually positive influence there, sort of a reverse peer pressure to the older years, and also to the younger years. Professor McGonagall said that better policing was also going to happen.
Slytherins do not take so well to being policed. You're too liquid and determined. Directing their efforts toward things other than infighting will work better than trying to disincentivize infighting. First years will have difficulty commanding respect; you will find this obstacle shrinks over time, and faster the more accomplishments you have to your collective names.
Hmmm, do you think Professor McGonagall would go for that? The no-policing thing? I like the idea of directing efforts, though, that feels nicer. Do you think I have any chance of getting the older students to change, too?
