It’s very weird to me that they wrote him out of the show, filmed an end to that character, and then fired him. Often when an actor abruptly exits a show they just vanish and you find out how they died offstage somehow. This guy had to participate in his own ejection from the show. His character kind of dies a hero, too, which makes it even weirder. I guess they were trying to jettison the actor without harming the character.
