I'm going to go with other. She chose to run with him, spend time with him. I think she should realize that they both simply need to learn each other's social norms and personalities. She is the newbie here, and she's got a lot to learn.
So far she's been played as a full moon. I think trickster would be fun, but I think that's a major shift away from how she's been built up so far.. Sports, brawler, etc..
I'm saying melee. Brawl was my first instinct, because she has attacked twice with bare hands. But she played lacrosse and knows what damage a club can do, even unintentionally. I think she's going to be smart enough to add heft to her hit. But maybe a wine bottle. They don't break like they do...
I'd say call Uncle Greg. I know you're a runner, but it seems like your want a fight more right now. And it might piss your mom off, a bus since you're angry with her.
