I loved how the witches with bows all stood there and watched the bad stuff happen before firing.....like, what was the point? I think that was my one Major nitpick of plot driven wtf.....Yeah, basically a series of overly-obsessive actions on both sides leading to tragedy. The witches planted an impulse in the padawan that was meant to drive him away but instead ended up drawing him in, Sol couldn't leave well enough alone because he was convinced Osha was destined to be his padawan, and the zabrak witch was so utterly against Osha leaving that she drove Mae to embrace her anger and pushed the others to take up arms.
I do wonder where Qimir comes into all of this - whether he was there somewhere behind the scenes, using his abilities to drive and amplify those obsessive behaviours, or if he just came along later and recruited Mae.
btw, did Sol just tell Mae all this? Like, he finds Mae, and says he'll tell her all, instead of turning the ship around immediately and asking where Osha is?
