I expected Lae'Zel to have at least *some* interaction of her own in that scene where you encounter the three enthralled sailors trying to help the dying Mindflayer, but ...nothing? xD
In the end, I had my character 'let them die. slowly', then took Lae'Zel and finished the Mindflayer off. Then at least I got a line out of her on how she killed a Gaikh.
