Hahaha, nice. That's what they get for taking away that poor illithid!
Plus, they're indirectly responsible for Zz'dtri's grudge, which caused Haley to be petrified in the first place. So, really, this is only fair. Qarr pissed her off last strip, and she said she was really in the mood to kill something.
That certainly didn't help but her problem with Elan is that he just cause a fight between her and Nale.
