Hi Athena, I'm Marina and I have two babies Athena may know: Milena Ivanova (16) and Iris Macnair (17) both sixth year Huffs.
Iris:
app*shamelessly copy-pasting text I wrote about Iris few days ago*
There's Iris Macnair, she's 17, and a Hufflepuff. Her family pretty much ignores her (except her younger sister and her former nanny, but no one knows that) because she's not smart enough, not ambitious enough, not polished enough so they like to say she always disgrace them (let's not forget the episode when she came home with her girlfriend so she could meet her family and they sent the girl back only about 10 minutes after she came). She's metamorphomagus in training, but she's not good at it, so far she only managed to partially change the appearance of her face so she could look like her sister and go to reformatory home, for stealing something, instead of her sister who really stole something. She was sent there during her winter brakes when she was at her sixth year, but came back few days before her finals at Hogwarts. She failed at Transfiguration and Divination, two subject she always struggled with, so they told her she need to repeat her year. Iris has never been interested academic success, so she would do everything again, even after knowing the consequences, to help her sister.
Mila:
her app is more like who she was before starting her fifth year than who she is now (I need to update it, I know, I'm the worst).
appIn a train accident that happened a year ago she lost her best friend and that kind of set her out of rails, she dyed her hair bright pink, start ignoring school, PA and everything and focused on her big secret evil plan (killing all the werewolves because they caused the accident), she'd eventually go back to being her old self, though not as happy and cheerful as she used to be, but currently she's quite unpredictable. I believe they'd know each other from their PA's meetings if nothing else.
