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?
"It's someone who's identical to you but isn't a twin and wasn't born at the same time as you and they're artificial."
"Like an identical twin where one was paused for a long time and also wasn't made in the first place until after the long time had passed."
"It's not how clones work either - and mostly clones don't work; they could but nobody really does it - but there are a lot of dumb stories about clones where they work that way."
"If it was a really good clone and cloned the brain too then they'd know everything the original knew, too."
"That's why I said cloned the brain too! Like, instead of just copying the genes, you'd copy the person as a whole!"
"Did you get much of anywhere with Cole and Astoria besides noting the poor quality of the Muggle Studies class?"
Sadde was watching the whole exchange with a smirk, but then says, "Oh, yeah. Astoria was only in it for the easy credits, and Cole pretended that was true of himself as well but he was actually really curious about how people deal without magic. I think there's some parents stuff going on there."
"Yeah, like, blood purism run in families I guess? So when I offered to talk to him without any witnesses he scoffed but then did show up. He's actually pretty nice, he's the one who told me—well, asked me about rubber ducks. Astoria was more flippant, but she didn't act disgusted by my very existence, and she thought Arens was a twat and I felt really really tempted to sow some discord there but I actually defended him! ...in a, you know, 'oh poor thing he doesn't know better' condescending kind of way but still it could have been much worse and I think I deserve a cookie for my self restraint!"
Karen grabs the most similar thing within arm's reach to a cookie (it's a frosted madeleine) and hands it over.
