The Walking Dead - Interview with Glen Mazzara & Robert Kirkman

Where does the first episode back pick up?
GLEN MAZZARA: Five seconds later. After the finale, finding Sophia in the barn is just a huge event that rocks our characters and changes everything on the farm. So, I think the stakes are much higher and people are dealing with a lot more. The storytelling becomes denser and just brings everything to a full boil.

Looking back, do you regret taking several episodes to look for Sophia?
ROBERT KIRKMAN: I think it was important to take the time to get to know our characters. It’s a good thing to lull people into a false sense of security, when the characters are experiencing a false sense of security. I think their time spent on the farm made the Sophia reveal that much bigger of a payoff, but is also going to inform just how the last six episodes are interpreted. I think, if they didn’t have that moment of calm, where we got to know our characters a little bit better and we got a sense that things were looking pretty good for them, this farm would have been a great place for them to be. In the next half of the episodes, we’re going to see that the farm isn’t that great a place. You have to build up what they have, before you can take it away. That’s really what makes the story more interesting.
MAZZARA: Yeah, I think we have a story that we’re telling over 13 episodes. That first half had a great payoff, and the second half accelerates the storytelling. I don’t know if we’d say that we regret any of the episodes that we did. I’m proud of those episodes and, if some people feel that some of those episodes were slower than others, I could argue that we were spending time with our characters.
