Played this character again today from a previous save where I saw her in my camp and didn't talk to her. Had done a long rest while she was there then went off and did other things. My next long rest I got the cut scene I should have had before. She had some kind of voices telling her to find me, unfortunately for her she had her hand on a blade. It didn't end well for her.

Pretty sure this may be some sort of bug, she only should show up during the long rest as the first time you speak to her, not just sitting in the camp randomly without talking to you.
