Hey, Bronte! It's Crystal, and I have 4 characters here, most of whom you'll probably remember from BNW, Bloodborne, and a couple of other games I played Charlotte in, though I have tweaked Charlotte and Amber a little. Tori's mostly the same, though.
Charlotte Bott (this journal) is a 5th year Ravenclaw, and before you ask, yes she is related to Bertie Bott. He's her grandpa. She gets a lot of free candy thanks to her dad and grandpa being in the family business of candy making, and uses it to bribe people to test her experimental potions. Speaking of potions, she's a prodigy in that subject. She's a little annoying in Potions class- she's that kid who knows all the answers and wants to show off. That said, she's not condescending or smug about the fact that she knows more than most of the other kids, she just likes the validation of being right. Charlotte also has an artistic side, and likes making jewelry, knitting, and music. She likes standing out- she sees it as better than disappearing into the crowd, even if it does mean getting made fun of. Charlotte gets on really well with the other girls in her year and is also in HILT, so she and Evie should definitely be friends! Maybe Evie could convert her to TV and movies, as Charlotte is pretty clueless about them and asked in a Disney discussion "What's a Disney?".
Rose Weasley (gardenrose) is a 6th year Ravenclaw and keeper for the Hogwarts Quidditch team. Rose is a little shy, and while she can open up a little and be friendly with those she's close to, she's more reserved, quiet, and a little nervous around those she doesn't know so well. That said, while Rose would prefer to avoid drama and confrontation, she will stand up for herself and those she cares about. Aside from Quidditch, her interests include gardening, herbology, and muggle technology. If she isn't in her dorm or common room, then you can probably find her in the Quidditch pitch, library, or the greenhouse. I don't know if she'd know Evie so well. She does have some exposure to Muggle entertainment, and used to watch some kids' shows before going off to Hogwarts, but hasn't watched much TV since then. She's more interested in video games and the internet when it comes to Muggle technology.
Amber Lyons (resinite) is a 7th year Gryffindor prefect. She's a muggleborn, and while she's fascinated and enchanted with much of what the wizarding world has to offer, she's less pleased with some of the more questionable aspects of it and seeks to change it, and hopes to do so by going into the Ministry. Amber is generally nice, but she's not afraid to call anyone out over overly douchey behavior. She's also not afraid to take away points should a situation call for it. She's not mad with power, however, and doesn't take away points for every tiny infraction. She does get pretty tough about stuff like bullying and harassment, though. Obviously they have the Muggleborn thing in common, and Evie's constant TV references would amuse her.
Tori Moon (not_sailor) is a 7th year Slytherin. is a 7th year Slytherin, Tori has the unfortunate situation of being materialistic in a family with a lot of kids and not a lot of money. So since she was a kid, she came up with all kinds of moneymaking schemes to get the things that she wanted. It was all little kid stuff, until a few years ago, when she set up a gambling ring and smuggled in contraband items to put up for sale. She's also a lesbian and has been out since last year, which was a hot item of gossip at the time. So if Evie loves gossip, she'd know about that. I don't know that Tori would really know her?
