Back in April, Morgan teased his son's upcoming appearance on the series, sharing a photo of the young boy in his zombie makeup. "My kid. Just a peek... as a dad, I have to say, I'd be hard pressed to remember a time I've been more proud of this dude," he captioned the black-and-white Instagram shot. "Can't wait for y'all to see him in action #gusydean #zombielife." Burton left an equally supportive message in the comments section of her husband's post. "I love my apocalyptic dudes. ❤️❤️❤️," she wrote. While this was Gus' first appearance on The Walking Dead, he's had experience with the show's zombie makeup in the past, according to Morgan. "The last time we did any zombie makeup on him, he looked at his reflection in the mirror and passed out," the star said during an April appearance on The Late Late Show with James Corden. "Now, that was a few years ago so I'm hoping he doesn't pass out this time around because the makeup's gonna be extensive and cool."
