"The Walking Dead" has departed until October, but the spinoff/companion series, "Fear the Walking Dead," is premiering its first six episodes late this summer on AMC. Robert Kirkman, who writes the "Walking Dead" comic books and executive produces both the main show and the spinoff, was at the 2015 National Association of Broadcasters Show with actor Steven Yeun (Glenn) and AMC president Charlie Collier, and they teased some TWD stuff ahead. You can watch a portion of the NAB Show talk in the video below, but here are five highlights:

1. Rick and Morgan are "spine" of Season 6
Season 5 ended with Rick Grimes finally face to face with his old buddy Morgan Jones, whom he hadn't seen since Morgan went loco in Season 3. "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 said (via TheWrap). "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 6."

2. Glenn's future is "cool," death may be "awesome"
Kirkman said "a lot of cool stuff" is ahead for Glenn, but are Glenn's days numbered on the show? Yeun admitted it "could happen" that Glenn dies, since no one is ever safe on the show, and the comic book sometimes hints in a certain direction. However, Yeun added, "The way that we make the show - the writers and everybody really want to focus on making things poignant and purposeful and meaningful. So if it were for Glenn to go, then it's probably going to be awesome."

3. Why that spinoff title?
Kirkman said the "Fear the Walking Dead" title means a lot of things, it's taking us back to a time when the walking dead were much more dangerous and more numerous. "So it's definitely time to fear the walking dead." Plus, he said, a title like "Walking Dead: Los Angeles" would've been the "exact wrong thing" for the show's tone.

4. More deadly people to "Fear"
Kirkman said he's always liked that the title "the walking dead" refers to both the walkers and the human survivors. "They are, in a sense, all just on borrowed time, and it's possible that the people that that we're following in this [spinoff] show are maybe a little bit more deadly."

5. No outbreak origin story coming
Kirkman said every other ZA story deals with the origins of the outbreak, and that's "not the priority in Walking Dead; that's not the priority in Fear The Walking Dead." They are instead more concerned with "the heart."
