Hello! I'm Kaylie and I've said hello in chat but here are my characters in reverse age order:
Ashleigh Spinnet was a Ravenclaw between 1984 and 1991, so they wouldn't have overlapped in school. She does, however, work with him! She's the Senior Operational Manager in the Environmental Law section. Which means she has a team below her but she still reports to the Deputy Director and Director General. She's been there nearly ten years so she definitely has seniority over Blaise, even if he's in a different department. She's pretty arrogant, pretty reserved, hates her job but won't leave it because it's secure and sensible. She barely knows the meaning of the word fun but is VERY organised and efficient. Oh, she's halfblood, raised in the magical world.
Bethanie Dunstan was a Hufflepuff 1988 - 1995 and was a Prefect so Blaise might dimly remember her. She wasn't a very effective prefect, mostly let people get away with anything. She's very maternal if that's something Blaise would've been interested in. She now works for the WWN writing/assistanting for Centaur Liaison Office. Oh, muggleborn.
Ron Weasley is... Ron Weasley. Gryffindor. Weasley. Currently works as a magical arborist (taking care of wand wood trees) because all his lofty career plans fell through. Doesn't hate Slytherins as much as he does in canon but isn't a big fan of rich people. Also quick of temper and prone to acting without thinking.
Andrew Kirke is everyone's favourite gay Scottish rockstar. He was the year below Blaise, Gryffindor. Halfblood, but raised mostly by his muggle mother. He's pretty cool with everyone until they prove themselves not worth his time.
So that's all of mine right now! Welcome to the game!
