You know... The rage works really well. Have you ever seen what happens when you piss a valley-girl off? They go from Alicia Silverstone to Large Marge in the blink of an eye, and really do just about grow claws and start tearing flesh off people. I can really see this. She has GOT to have rage issues. Like maybe she's been sent to anger management classes a couple times, or got booted from the family because of an 'incident' and that's why she's adventuring now? Just spitballing backstory ideas here...
