Hi again! Let me introduce my Hogwarts-related characters. Maybe some of them will strike your fancy
This account here is Christian. 7th year Hufflepuff, co-leader of Potter's Army. He's the younger Zabini twin and is very friendly but recently has become a bit more reserved because his best friend was sent to the hospital wing by another student (her rival, Pavo). If she is interested in the PA, she might be able to subtly ask him about it, but he's also happy to talk about almost anything. During the summers, he runs Quality Quidditch Supplies because Blaise handed the shop over to the twins and his brother doesn't want to be involved. Christian stopped playing Quidditch after a bad accident during a game, but he's better about it now.
<-- Apollo. Elder brother, 7th year Slytherin. Definitely in a secret relationship that people found out about, they pretended to break up, but they're still together. It's a mess. He's graduating early in December because he got permission to take his exams early. He is training to become a healer and kind of working for the Minister of Magic. He's getting his apprentice hours in by working in the Hospital Wing at nights/on weekends, so she might run into him there or in the library where he studies with the next character:
Naomi Mulciber, 5th year Slytherin. She's a legit nightmare, but not because she's particularly effective. She's just mean. Her sister is a Gryffindor student, and they super don't get along. Naomi was kidnapped (part of her backstory before I took the character on) so I decided she takes out her frustration on those around her now that she's back and feels like people didn't try hard enough to rescue her. Bully material if you are looking for that.
And also there's Keiran Hayes, Headmaster and Transfiguration professor. He used to be the head of Slytherin until two years ago, but that's not super relevant for Lauryn. He's taught Transfig on and off for a while, though, so she would know him very well. He's a semi-recently divorced father and pretty broody but he's got a good heart in there. He's the one who, with his friend Kenna, initiated the Quidditch Fundraiser for students who couldn't afford school supplies/etc. That event is still on if Lauryn would be curious. It's a bunch of staff and their friends trying to beat a professional quidditch team (lol).
