i could offer meredith here up as someone that would have helped/pushed ivy to be bolder and stand up for herself. mere's a 7th year gryffindor, and while she's far from a bully she does wear her heart on her sleeve and has a temper sometimes. she is extremely blunt, but it's because she thinks beating around the proverbial bush is just a waste of time and she doesn't believe in that. she's an adrenaline junkie and always wants to party and have a good time first and foremost. she's highly intelligent and has an easy time with school, but doesn't actually focus on it much at all despite being so smart.
