Love it! I'm not playing anything super heavy from canon. I'd say the cliffnotes are:

-likes to pretend she's old timey british
-speaks in pop culture references
-social faux pas are who she is
-legitimate explosives expert
-family issues b/c her parents were kidnapped and experimented on by the former megalomaniac corporate overlord, and then her surrogate dad was killed by him. She had kiiiin of recovered and started making friends with the others, but being ripped away again is not great. But she's 13 so she hasn't processed that at all.
-the only person here from her world is claptrap and he's uh dumb and terrible and a robot

If there is anything you want me to steer toward for conflict/button pressing I am happy to do so.
