So: This is Aimee. I'm working on this girl because I made the mistake of mentioning her in that check-in post, and now she absolutely will not leave me alone.
So, I'm thinking she's going to be Megan Jones, who is a class of '98 Hufflepuff. (I was looking for other names, then I decided it amused me to use Martha Jones' actress for Megan Jones.) She's a hitwizard, which always seemed like the less-glamorous law-enforcement career in the wizarding world. I don't know if it's quite beat cop compared to detective, but maybe kind of how the FBI is compared to local police departments in crime shows? FBI gets the funds and attention and glory, while the local departments get sort of resentful when the FBI shows up to steal the show? (Veto me on this if need be, Jenn.)
Personality: She doesn't really go for the "sweet, unassuming" 'puff stereotype, aaaand it kind of annoys her when people assume she will be. She has attitude, determination, and she'll kick your ass if she has to. She also has a bit of a temper on her, so she might kick your ass if she doesn't have to. (She NEEDS a partner; she's good at her job, but someone else has to be around to go "JONES. TAKE A DEEP BREATH, JONES.") But she's willing to do unpopular jobs because someone has to do them. Not everyone can get the high-profile, exciting cases; someone has to go arrest the flasher in the park and the three-time-offender domestic disturbance.
Anyway! I need some connections, although she sort of has enough built-in ones just by being a Trio-aged character. I'm thinking her older cousin is Gwenog Jones of the Harpies, so that'd give her some distant quidditch connections. Fellow law-enforcement types: Surely the aurors must work with the hitwizards, even if aurors specialize in dark magic. Ministry types: She'll be around the Ministry, so lunchroom shenanigans, political intrigue. Old Hufflepuff schoolmates: Hit me with what you've got, love her or hate her.
