We’re gearing up for an epic return.

As you can see, it wasn’t really your standard preview–mostly just an announcement that production was underway along with some behind the scenes footage and a few quick scenes.
It makes sense that he’d be part of the cast since Maggie is making a full time return to the series. That being said, it was still a great surprise to see him show up, especially wearing Glenn’s old baseball cap. No information has been released on who’s playing Hershel, but I’m sure we’ll find out soon.
The Walking Dead returns on February 28 with six additional episodes for Season 10.
