"A railroad track...going on forever, into the setting sun. From behind camera, a single individual walks down the middle of the tracks...into the setting sun. Voiceover. You realize that that individual is Carl...all grown-up, a man of his own. No one else is with him — just him. And as he does his voiceover, you realize that everything, all the seasons that you've just seen is him reliving his past. So everyone on the show is dead. He's the only survivor, and he's on his own and walks off into the sunset. And that's the end of the show."
