Spoiler A woman named Alpha, who leads a group called the Whisperers that uses walker skin as masks to blend in among herds. They're pretty much nihilists who want to live like animals rather than part of a society. Maria Bello was rumored to have been cast in a part on the show in season 8 a long time ago. Many speculated that this would be Alpha, but it turned out to just be a rumor as neither Alpha nor Maria Bello appeared on the show this season. But given all the changes the show has made, who knows what will happen. The Whisperers would be a logical next step, but Carl played a big part in that storyline in the comics so I don't know how they're going to approach that.
