'The Walking Dead' Character Confirmed To Join 'Fear' Season 4?

The Walking Dead may have accidentally revealed which of the Walking Dead series the "Worlds Collide" crossover event will be taking place on.

Ahead of the reveal scheduled for Sunday's post-The Walking Dead Episode 8x06 Talking Dead show, Skybound's The Walking Dead Twitter account sent a tweet which has since been deleted.

"TOMORROW you will discover on @AMCTalkingDead who from #TheWalkingDead will join #FearTWD Season 4! Who do you think it is??" the tweet from @TheWalkingDead read.

It's worth noting, Skybound's The Walking Dead Twitter account is not directly associated with the AMC series nor is it managed by an AMC publicity team. The tweet may have come with inside information, having been deleted after a note from AMC's team was sent to Skybound's, or the responses from Twitter uses may have been enough to prompt @TheWalkingDead to delete the account.

Sunday's official crossover announcement comes on the heels of the cast and crew of Fear the Walking Dead heading to Austin, Texas in preparation for production of the show's fourth season, the safe bet is that the crossover will take place on Fear the Walking Dead. As noted by Victor Strand actor Colman Domingo, fans of the AMC shows are going to spot actors on set which often reveals spoilers -- meaning the reveal is just in time for an official announcement to take place ahead fans' set photos revealing the news.

Following the announcement, speculation pointed to Michael Cudlitz reprising his Houston, Texas-based Abraham Ford character on Fear the Walking Dead. While Cudlitz says the idea is "awesome," executive producer Greg Nicotero debunked the theory on an episode of ComicBook.com's After the Dead.

Sunday's Episode 8x06 of The Walking Dead is titled, "The King, The Widow, and Rick." The officially synopsis for The King, The Widow, and Rick reads, "With things looking up for Rick and our group, an argument breaks out at the Hilltop. The consequences of the decision are life versus death."

Fear the Walking Dead returns for its fourth season in 2018. The Walking Dead airs Sundays at 9 pm ET on AMC. For complete coverage and insider info all season long, follow @BrandonDavisBD on Twitter.
