Bert is wandering near the castle most of the time, but ranging farther to hunt people down and keep from getting bored. He will definitely be up to kill/maim/hurt anyone who wants it. He's still on Gunslinger autopilot at the moment and ignoring his feelings.

I'm, as always, happy to have him kill people. I wouldn't mind having him team up with someone, too, but it might take some wiggling to do that.
