I mean, first there's Ginny, right? she'll be stoked to meet one of her uncles, if not a little weirder out. but mostly stoked!
of course there's also Victoire. she will be much curious! the more family the better, right?!
also Marlene! order bros! plus she'll SUPER understand the epic trauma he's about to go through with the whole "yep you super died, sorry." I imagine she'd appreciate his flirting, but you know... she's gay so mostly just patted his head and walked away.
Tracey would be super interested in knowing a fellow writer/journalist, as it was actually her first career choice. plus she's generally ok towards people who don't immediately go "ok slytherin bye"
Terry likes almost everyone. I imagine he'd super get on with Gideon.
