"The Walking Dead's" fifth season ended just a few weeks ago, but executive producer and co-creator Robert Kirkman, AMC president Charlie Collier and actor Steven Yeun are back on track with some new details about the show's sixth season via TheWrap.

"Having Rick and Morgan together, finally, again is a huge deal, and it's definitely going to be a big part of Season 6," Kirkman teased. "Now it's a very different Rick and a very different Morgan who are going to have a completely different relationship. 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 and Yeun also joked about character deaths on the show. "We don't kill the popular characters," Kirkman quipped.

"If I go -- that could happen," Yeun said on a more serious note. Yeun, who has played Glenn since the first season, spoke a little about just how he would go out. "The way that we make the show -- the writers and everybody really want to focus on making things poignant and purposeful and meaningful," he shared. "So if it were for Glenn to go, then it's probably going to be awesome."

"Our longterm goal was to tell this unrealistically massive huge story, so by going season after season after season, we actually are maintaining the integrity of what we originally set out to do," Kirkman shared. "So I think there's a possibility to go for many, many years."
