There’s never been a shake-up in The Walking Dead universe quite like the one you’re about to witness on Fear the Walking Dead season four. The show, which is known to be quite a bit more nomadic than its older sibling, has moved from the U.S./Mexico border to the Austin, Texas area. That’s not all: Two new showrunners, Andrew Chambliss and Ian Goldberg (both worked on Once Upon a Time), have replaced Dave Erickson, who co-created the series with Walking Dead mastermind Robert Kirkman. There are also a few new characters joining Madison, Alycia, Nick, and Strand. And there’s even a time jump that kicks off the season!

But none of those game-changing details can top this one: Lennie James, who until now has played Morgan Jones on The Walking Dead, has joined the main cast in a once-unlikely crossover. The troubled pacifist Morgan journeys all the way from Virginia to Texas in the hopes of finding peace. Unfortunately, he quickly discovers in the season four premiere, “What’s Your Story,” that he can’t avoid conflict forever.

While I won’t spoil exactly how Morgan crosses paths with the other characters or what exactly the fourth season is up to, there’s plenty I can share from my recent set visit in late January. I had the chance to check out some filming as well as catch up with the show’s stars and new additions. I also visited a brand-new set inside of a baseball stadium that’s unlike any settlement we’ve seen in this universe before. I even learned quite a bit about FTWD’s two-hour premiere on April 15, which kicks off a brand new story for the show.

Here’s what you should expect when the walking dead arrive in Austin next month…
