I wonder if they'll reference the batshit Millicent plotline from one of the old Harry Potter games? (I think it was the PS2/Gamecube Prisoner of Askaban game???) She had a bigger role in a game (if I remember she was Hermione's potions lab partner). Millicent revealed she's a half blood, and hilariously implied her mom was a poor Soviet bloc mail-order bride who just assumed Millicent's father being a wizard/the wizarding world was a normal cultural difference. She was written as a stereotypical tough Russian/referenced old Russian proverbs, and talked about going hunting with her mom and being taught to skin animals. She even had a side quest where if you find her lost marbles (she was obsessed with playing marbles -is that a Russian thing?), she gifts you a healing potion.
