Hi Dana! It's me, Lily. I have too many characters. They are all listed here. We can lines with whoever you want but I have a few ideas!
Neville wants to be friends. He's in her brother's year obvs but he's super friendly and most of his closest friends are younger than him. He appreciates her joining the courts because Harry's being a butt, because Neville also has to focus on duty rather than the things he wants to do.
I also have Colin Creevey who's a year older than her. He had a crush on her brother when he was first discovering boys, but we don't talk about that anymore. He's a photographer by trade and a muggleborn so he's well below her station. He's just here to have a good time.
Peter is an "uncle" of sorts, since her dad is one of his best friends and he works with her mom. He hasn't betrayed anyone this time (yet). So he's nice! Probably gives good Christmas presents.
Dax is a muggleborn who her mom really helped out when he was a kid by taking an interest in him. He's a fair bit older than her, but he still hangs around because he owes a life debt to Lily and James has employed him to keep Sirius' stupid butt safe.
If you want anyone else for lines we can also make it happen! Those are just off the top of my head!
