The Walking Dead
Lennie James as Morgan in The Walking DeadAMC

In last Sunday's episode of The Walking Dead season 6, Morgan appeared pretty worked up over something he built in one of the houses in Alexandria. Fans were left wondering what he has been up to. Well, the show's executive producer and director of the episode, Greg Nicotero shared some intel on that, and in the process, dropped a potential spoiler for season 7.

Nicotero revealed that Morgan is in fact building a jail and elaborated a bit on the reason behind it. "Yes. He's building a cell," the EP told Yahoo! "The jail cell that they had wasn't necessarily much of a jail cell. It was like a little room with a little metal gate. I think Morgan is committed to the next time they have somebody in there, if they need to, they'll attempt to rehabilitate them. He wants to be equipped. It goes back to his story with Eastman. Let's be honest, Jesus didn't last very long in that place. It can't be that secure."

Warning: potential spoilers ahead

A jail that might probably host a deadly villain in the future? ComicBook.com reports that in The Walking Dead comics, Negan ends up in an Alexandria jail cell after Rick rules it inhumane to kill him. "That's a big change from the Rick Grimes we're seeing on TV lately, but it's always quite refreshing to think that he can get back to that point," states the site.

TWD season 6, episode 13 titled The Same Boat airs on 13 March at 9pm ET on AMC. As per the official synopsis, "Two different groups leave Alexandria on supply runs. While both are concerned with the future of the community, immediate danger will derail them."
