“For instance lot of people used to think Rick and Carl were immune even after all the times he’s shut that theory down.”
Back in 2018 the show’s creator Robert Kirkman addressed the possibility of immunity.
He told Comicbook.com there were a number of reasons for his decision.
Kirkman said: “One, because it’s been done on a lot of other zombie stories.
“And two, because you know it’s kind of a mythology-breaking proposition.
“You don’t want that kind of thing as far as somebody being immune. And we have dabbled in that a little bit in the other show [Fear The Walking Dead].”
The Walking Dead season 10 returns to AMC on February 23
