But did the team at Alcon go back and revise the ending of this latest episode?

“The truth is,” franchise co-creator Ty Franck says, “it’s kind of a meaningless question in television, because as an on-set producer, I have literally walked off the set, climbed the stairs to my office, and rewritten a scene we’re about to shoot. And Naren has done the same. Daniel has done the same. I mean, that is part of the television process. So there is no sort of ‘once the story is set’ when you’re in the TV realm.”

In other words, they definitely did rewrite him out of the show, they're just trying to pass it off by saying that rewriting is common anyway.

That was years ago. Has there been any progress in the investigation? Or is it still just allegations?

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.
