My expedition leader got in a bit of a quarrel with a wereskink that decided to prey on my dwarves. The battle was short, as my expedition leader simply beheaded the wereskink with one blow. Working as a woodcutter has its benefits, including a battle axe. However, the wereskink got in a hit before it got decapacitated, bruising the fat of his left hand. Thus, he is now infected and transforms once a month.
The kicker is: My fort is under a year old, with only 19 dwarves. Thus I didn't have enough force to kill him while he was transformed, and he killed three of my dwarves and transformed back. Now he is back as a citizen of my fort. However, he does not listen to orders. He has resigned to hang around aboveground about 20 tiles from my entrance, listed with no job. I can still access his thoughts and preferences screen, and he is apparently content. However, if any of my dwarves get too close to him, they will cancel their jobs and run away. In the nobles screen he is still my expedition leader.
Now, what do I do with him? He will transform again next month, so I don't have a lot of time to find a solution. I could probably kill him now before he transformed, but I worry that it would cause a loyalty cascade, considering he is still a member of my fort. He still shows up on the citizens list. I was planning on using burrows to place him for an unfortunate accident involving drawbridges, but he refuses to listen to orders and I can't build around him, since my dwarves get spooked.
Here's his thoughts and preferences:
