I think Lez may prove more dynamic in this regard. I have a feeling she can be turned later. It is fairly obvious she is bound for disappointment and disillusionment in her personal quest. I have had a few exchanges where she has expressly disagreed with my decision but approved of my handling of situations. Despite the fact I cannot bring myself to play the villain in a video game (I am terribly in love with tragic heroes whose inherent flaws ultimately lead them to destruction), she and Shadowheart along with Wyll are whom I will be taking into Act 2 with me. I am sucker for redemption stories
