At the TCA (Television Critics Association) press tour today, Showtime’s president, David Nevins, revealed there’s still a chance for a Dexter spinoff. And that if it happens, it would be about… Dexter.

Said Nevins, “It’s something we continue to talk about. If we were to do it, we would have to have a very good reason to do it. It would have to feel like it’s a new show. I’m not interested in doing it if it’s just a continuation… There have been some light, ongoing conversations. It hasn’t really gone anywhere yet.”

The question up until now had been who a Dexter spinoff could focus on, with many of us guessing Yvonne Strahovski's Hannah McKay. When asked the question today about who a new series would include, Nevins replied, “It would have to involve Michael [C. Hall].” Asked to clarify whether he meant as a producer, Nevins said he meant onscreen, remarking, “I think if we were to do it, I would only do it if it with Michael.”

The Dexter finale received a lot of criticism, but Nevins said he felt, “The fundamental design of where they ended Dexter was really well-conceived. He had to sacrifice the one person who was closest to him in the world and he had to leave and that was where it was headed for a very long time.”

Dexter executive producer John Goldwyn said that Showtime demanded Dexter survive the end of the series, but Nevins denied that today saying, “Honestly, it was never even discussed, the idea of killing him. The people who were really in the center, which was Michael, Scott Buck, Sara Colleton, it was never even… no one even brought up the idea. It wasn’t discussed.”
