AMC is catering to its dedicated fans who just can't get enough of The Walking Dead.

Episode 4 of season 6 will be 90-minutes long, AMC announced today, dubbed as The Walking Dead Mega Sunday. In the all-new episode, titled “Here’s Not Here,” written by Scott M. Gimple and directed by Stephen Williams, the survivors must ask themselves who can be trusted, and better yet, can they change?

Could this be the flashback episode Scott Gimple revealed he was working on at San Diego Comic Con this summer?

During the 90-minute episode of The Walking Dead, AMC will air the world premiere of the trailer for AMC’s upcoming, highly anticipated series “Preacher,” as well as the television premiere of the “Into the Badlands” trailer.

The Walking Dead airs Sundays at 9 PM ET on AMC.
