I would really like Kristina to work her way into becoming a Badass Mobster. Or a chick who knows how to handle a gun and is not afraid to use it (like Sam but in my mind Kristina would abuse the power in certain situations). Great story material can come from it:
1. Taking the job from Micheal 2. Pissing off/worrying parents 3. Great Ethina material:
Ethan: What…how did this happen?
Kristina: I’ve been burned, one too many times. I decided it was time to take matters into my own hands.
Better than Micheal becoming a Mobster because this would be something no one saw coming. And it fits because she was a victim of domestic violence and it could be an FU to her parents for trying to control her life i.e fixing to get her into Yale.
