Wait, if you're still taking suggestions, can you do a Slytherin-Gryffindor friendship? It doesn't have to be Draco because it'll take a lot of rewiring to make that work, but maybe someone like Millicent who isn't as hard-headed? Or maybe more Ravenclaw/Hufflepuff rep, especially more inter-house friendships. I think it'll be funny if at some point, one of them goes to sit at another house's table because "they're my friend 😐 and there's no rule against it except for like on three days of the year. stop looking at me weird"
Yes, I’m still taking suggestions!
I actually plan on having some OCs in my rewrite because most of the Slytherins in the books are explicitly part of Malfoy’s gang, therefore wannabe DEs. But, I can definitely try and have someone like Millicent be friends with another student of a different House/Gryffindor (they’d have to be pureblood, but yes).
As for the Hufflepuff and Ravenclaw rep, I’ve already developed several students for both Houses for the Marauders and Golden Eras. I think they’d be so fun to write. I’m so excited!
