I was finishing up the lost shipment quest. I handed it in and was told I was welcome, friends, whatever. Well I walked a little bit towards the other end of the cave, up top where Zarys is, and combat initiated. Well I killed everyone, except the "pet artist". When I talk to the artist he asks if I've talked to Brem to buy him. There is no dialog option saying he was dead or the artist no longer has to worry, etc. If something requires another person to release them from servitude, or whatever, once that person dies, the captive should be allowed to leave.
