I have an NPC in a dungeon, who's supposed to be a prisoner, and is shackled to the wall. The problem is, as soon as combat starts, he runs around commenting "ooh, my money's on the big one!" and "I'll find whoever did this!" and all the usual sort of stuff.
Which, obviously, I don't want him to do. He's a member of CaptiveFaction, so I suppose that could have something to do with it, but if I tried making him neutral to anybody in the dungeon, they're going to attack him.
So, what do I do?
