I had left her at camp - she is fairly redundant in my party since in first playthrough my main's a cleric - and she showed up in the tiefling/druid camp and had apparently disinvited herself from mine. As I said, I hadn't done much with her, but it would annoy me if now I have lost the chance to do her personal quest or anything.
You can't do her personal quest in the EA.
The only thing you are missing out is convincing her to tell you who she worship if you haven't done that yet, but she needs to be in the party while exploring certain places for that convo to happen.
