Beware, there are season five spoilers ahead.
The Walking Dead season five finale ended with some awkward timing for a reunion between Rick and Morgan. Rick's long-lost friend from the pilot and "Clear" walks up right as he's summarily executing Pete. Given Morgan's compassion shown throughout the episode, we can imagine Morgan being appalled. It could even be central to their relationship going forward.
Creator Robert Kirkman said the dynamic between Rick and Morgan will be pivotal season six. "Now it’s a very different Rick and a very different Morgan who are going to have a completely different relationship," he said at the National Association of Broadcasters Show. "And it’s the questions of how they’re going to interact, how they’re going to work together—if they’re going to work together—and what comes from those interactions is going to be basically the spine of season six."
Kirkman also touched on Fear the Walking Dead, which he says won't be a straight up prequel to The Walking Dead. We're not going to get the full story of how the zombie infection spread. "That's not the priority in Fear The Walking Dead," he said. "Every other story deals with that stuff, and we're concerned about the heart. It's not about fixing this world, and it's not about learning what the cause is."
Because the spinoff is taking a step back, the zombies will be more dangerous and more of a focus on the show. It's even "possible the people we're following on this show are a little more deadly."
