That pic was a freeze frame from the Dexter/Ray Donovan joint promo on Sho's website.
In April 2013, following ongoing fan speculations, Showtime announced that season eight would be the final season of Dexter, however Dexter showrunner Scott Buck earlier this month told NBC's Today show that Dexter would not gain the happy ending he wants: “I don't believe a serial killer can walk happily into the sunset. Otherwise, I would feel very uncomfortable about sending that message out that serial killers are great, they're fantastic and deserve happiness.”
God I hope they don't do that. And yet SB thinks of Dexter as a superhero. There might be a clue in what MCH said about the VOs - "who is he talking to?". If they tie that in somehow like he's talking to a journalist or novelist, at least it's something that's been consistent through the seasons.
