In a separate interview, Angel Theory told Insider that she was also excited about the smarter walkers on the show's final episodes for the same reason as Gilliam.
"The normal walkers, they're just slow," Theory, who has played Kelly since season nine, said. "I feel like you can kill a few of them. Now, we have more of a challenge. We have to run faster and really focus on trying to survive now. Now, you have to be quick-witted."
Theory hinted that someone may get left in the dust if the smarter zombies are chasing a few survivors.
"If someone is hurt, if that's the case, you might have to leave them behind because now you got walkers that are running and doing backflips and stuff," Theory said.
Are we about to see zombies doing backflips?
