Ok so I think I once said my Slytherin girl MC/OC would graduate from Hogwarts to play Quidditch professionally, on the same team as Imelda. Well, my Slytherin (I often call her Yu cus her real name is too long, and it has accents, so I'd have to copy/paste it all the time if I wanted to type all of it cus my keyboard has no buttons to make letters accented, whompity-whomp) would play as a Seeker and be the captain of the team (also seb would be on the team, but as a beater), but she'd have Imelda be appointed as the next captain once Yu becomes an Unspeakable and eventually a Supreme Mugwump (she's the only hl mc of mine who would be an unspeakable besides cyrene dumbledore, but cyrene was only briefly an unspeakable before moving on to other equally high, respected positions of power, and but yu isn't the only one of my hl mcs to become a Supreme Mugwump tho, I headcanon that Yu was born here but only raised there until she was 8 years old, and her returning there to go through the ceremony to become a Supreme Mugwump would be symbolic, she'd retire from being a Supreme Mugwump on her, I dunno, 30th anneversary of being one cus symbolic again, and she's still live here but occasionally visit Isidora's house and perhaps Rookwood Castle and Feldcroft as well as the Scottish Highlands in general, she'd also occasionally have long, grand, fun vacations around the rest of the world for her own enjoyment, sometiems taking Sebastian with her and also ominis and her other friends, both the ones from slytherin and not, and yuand seb be a happily long-married couple by then <3)
Also, she would FOR SURE call imelda "mel" for short, because they are really close and see each other as sisters <3 (sisters with a rivalry, but a friendly kind of rivalry! they really respect and admire each other <3)
