I have a savegame handy to get out of this, but anyway ...

I've been playing an evil bastard on my first trip through MotB, which means I've spent the whole time doing things that appal Kaelyn. So I show up at the City of Judgment and siding against Zoab of course causes her to abandon me. I rather suspect it was because I had such negative influence with her. So two questions ...

If I side with Zoab and Serryu and the other Crusaders, will she stay on board?

If I play as a good character and score high influence with her, can I convince her to side with the defenders?
