Not quite as vicious and uncaring as the rest of the maniacs loyal to Ashur, Bone guards the slaves inside the Mill, and is generally unpleasant to speak to until you prove yourself in the Arena. Once your mettle is unquestioned, Bone changes her tune, and you can receive a semblance of a civil conversation.
She is one of the few Pitt raiders that respects you for being in the Arena.
Bone will immediately flee as soon as the slave uprising begins, instead of helping the other raiders fight the slaves. The rebelling slaves will often chase her down and kill her if the other Pitt raiders don't kill them first.
