“In the very last scene of the series,” Philips explained, “Dexter wakes up. And everybody is going to think, ‘Oh, it was a dream.’ And then the camera pulls back and back and back and then we realize, ‘No, it’s not a dream.’ Dexter’s opening his eyes and he’s on the execution table at the Florida Penitentiary. They’re just starting to administer the drugs and he looks out through the window to the observation gallery.
“And in the gallery are all the people that Dexter killed—including the Trinity Killer and the Ice Truck Killer (his brother Rudy), LaGuerta who he was responsible killing, Doakes who he’s arguably responsible for, Rita, who he’s argueeably responsible for, Lila. All the big deaths, and also whoever the weekly episodic kills were. They are all there.
