Annie: On a personal level, I despise betrayal, and turning against family is a special kind of betrayal. This likely means I am harder on her than on the others.
My first problem is her internal inconsistency. On the one hand, it appears like she is or was massively into the MC, but also slept around without problem. Her outright denial of giving a close friend the okay to get together with the MC speaks volume, but on the other hand, there is no issue with her blowing a near stranger. It is like he is not truly worth going after completely, but at the same time no one else should have him and she herself can also do what she wants. The attitude is so hypocritical that I find it hard to see any positive qualities in her.
I think one of the main issues is, that we only saw the betrayal and her taking the side of the bitch squad, but nothing from her being an actual good friend to the MC. She was supposed to be close to him, and we are only told that, but never shown. This leaves the scales clearly in favor of negative portrayals.
In nearly each scene, she comes across as confrontational and not nice. It feels like it is turned around and MC is the bad guy, who stood aside while she was being humiliated, attacked, mocked and hurt. At least that is how she acts. Even the scenes, where she actually is helpful, come across as reluctant on her part.
Finally, with the pictures being sent from the same source, she already confirmed the bitch squad was responsible for it by stating that they did leak the pictures from the sorority. I hope for the chance to confront her with that fact. She seems like the most obvious hook to destroy the B5 from inside.
