I still have a particular fondness for that douche ex machina Dreamer Tatum, but since that isn't an option, I chose Banzin, aka TheMastersNemesis. He seems to vanish and the nastily reappear for a short while, like herpes. Unlike herpes, however, he will die someday, and of course I hope it's soon.
Apropos of nothing: The Magistrate has been getting that tea service for a long while now, hasn't he? There hasn't been one Magistrate post, sir, for over two months now, sir, which, sir, is a concern, sir.
Maybe he was an extra bad boy and is now decomposing behind a false wall?
