Okay, well here is what I'm thinking, and let me know if you wanna do something else.
Brit and <Eve> have been friends for awhile. Brit, however, is a bit of a social outcast, coming from a broken home, and has always been somewhat self-conscious about it. <Eve> likely knew Brit before the falling out occured, and so they have remained friends, but Brit has always felt somewhat inadequate. This has led Brit to always feel like she doesn't really measure up (whether <Eve> has actually taken a dominant role in the friendship is up to you, Brit at least will act as the sycophant
However, recently, Brit's slow decline into the darker aspects took an abrupt nosedive when she found herself and a gang of other hoodrats picking on a preppy kid. The kid tried to fight back and ended up getting knifed by one of the gang, and Brit found herself as an accessory as she went into hiding. This was also about the time she ran into Blake (Innocence), who also ended up as an accessory. Brit, for all her posturing, was NOT built for murder and Blake ended up having to do what she could to reassure and comfort her, which of course led to their secret lesbian relationship AND their fleeing from the cops.
Brit had already agreed to come with <Eve> out to the camp and Blake thought it was a GREAT place to lay low, so the two of them showed up to help get the camp ready.
Now, of course, I haven't established why <wander> and <Volante> are out here... and both Eve and Innocence can modify my backstory as they want, but I figured I'd get the ball rolling
It is also Eve's turn to use her final die :)
