Hi Gina! I'm Becca and I've got FIVE for your perusal because A) I'm a crazy person, and B) I was laid up with an injury and nothing better to do than, you know, write a bunch of apps!
The first is Stella Fawcett (astellaidea) who is a 6th year Ravenclaw. Stella is probably one of the most popular girls in school, just because she's SUPER FRIENDLY and kiiiiiiinda boy crazy. I don't think she'll have much interest in Fleur tournament-wise since she's been friends with Cedric since they were five (they're neighbors), and she's throughly rooting for him. Unless a certain other Hufflepuff starts mooning after Fleur, she won't have any reason to seriously dislike her however. So, she's likely to be friendly. Stella speaks French fluently and spends lots of time in France with her grandparents and LOVES to shop and talk about clothes and such, so they could probably find some common ground.
Then I have Amelia Higgs (misshiggstoyou) who is a 5th year Slytherin. Amelia will not like Fleur. Amelia doesn't like most people to be fair, but she will especially dislike Fleur because she and Roger used to date. She broke up with him, but still, having your ex rebound with some French Veela is offensive.
Next is Ava Rosier (this journal), 7th year Gryffindor. Ava is the secretly halfblooded daughter of a dead Death Eater. She's quiet but kind (with a lot on internal emotional issues, but that's neither here not there). She probably finds Fleur intimidating, but would be nice if it came down to it. She's best friends with Ruby and might notice Ruby noticing Fleur. So, there's that.
Elena Gregorovitch (caffiendishly) is a Durmstrang 6th year. She functions in a quasi-constant state of deadpan sarcasm. She will mock Fleur. She mocks everyone. But, secretly, I think Fleur probably makes her feel a bit bad about herself. Especially since Elena is one of the lads and finds the way that Fleur can wrap boys around her finger, well, unfair.
And then I have Elodie Chevalier (jesuiselodie who is from Beauxbatons! Elodie is Head of Class 7E. She's sort of the French Hermione in that she's super intense and type-A and works exceedingly hard at everything from her marks, to Quidditch, to playing violin, etc, etc (she was abandoned by her father and her grandparents to be raised by her teenage mother, so she feels like she has something to prove). Part of her is deeply annoyed by Fleur because she doesn't approve of people who don't have to work hard to get the things that they want. And she also really, really wanted to be champion (even though she would have been terrible because not being able to plan for the tasks would have driven her batshit). However, there are only six French girls and she feels they ought to stick together. And Elodie's bestie is Sophie who is nice to everyone. So, I think she will try to be understanding and friendly. Unless Fleur tries to Veela one Calvin Fawcett, Slytherin 7th year, who Elodie has been dating since the summer. Then all bets would be off, haha.
