At today's Television Critics Association panel with Showtime, there were hints about a potential Dexter spinoff.
Showtime entertainment president David Nevins announced that the cabler had inked a two-year deal with Dexter showrunner Scott Buck to develop projects for them. And while he isn't going to come out and say it, he did say, "We announced a deal with Scott Buck today, draw your own conclusions." Nevins was quick to follow that up with the fact that no deals with any of the current Dexter cast members has been made, and that "it's not necessarily a spinoff." "All options will be explored. We're really not dealing with it at all until we're through this season and maybe for a while thereafter," he told the panel. "We have a deal with Scott and we're going to develop a bunch of different things with him, there's nothing else to be concluded at this point. There's no sense of whether it will happen and if it will happen but I want to stay in business with Scott."
That is one of the greatest non-committal statements I have ever heard. If I had to guess, I would say that a spinoff is certainly not out of the question (some have suggested that Deb would be the focus, but I think an even more interesting angle would be on Harrison), but in reality, I think it is all a big tease.
