Rick and Morty fans will remember the months upon months of waiting between the end of season two and beginning of season three. It may be time to batten down the hatches and prepare for another dry spell.

Ryan Ridley, a writer on Rick and Morty, told the Detroit Cast that no one is working on the script for season four yet, as far as he knows. Ridley pointed out that the script for Rick and Morty’s third season was finished in November 2016, about eight months before the show returned to Adult Swim. Since then, however, he hasn’t worked on it and is adamant that other writers haven’t either.

“They really take their time,” Ridley said. “I never understood why everybody — all parties, Dan, Justin, and Adult Swim — didn’t get their shit together, and make the show fast; I just don’t get it. It doesn’t make any sense to me. I’m sure they all have their reasons.”

Ridley said that, based on how long it’s taken the staff to get the scripts written and the episodes animated in the past, he would be surprised if the fourth season debuted before late 2019. If that were the case, it would mark the longest inactive period for the show, surpassing the 18 months people waited for the third season. Ridley added that he was positive a fourth season of Rick and Morty would air — he just wasn’t sure when. An Adult Swim representative told Polygon there was no comment at this time, but confirmed a fourth season had yet to be ordered.

“Get your shit together, you guys,” Ridley said. “Get it all together, and put it in a backpack.”

Polygon spoke to Rick and Morty co-creator Dan Harmon at New York Comic Con in October, and he confirmed a fourth season was happening. Harmon also told Entertainment Weekly in September that he was “about to do” the fourth season of Rick and Morty, but didn’t provide an update on when production would start

“I want to prove it with the first 10 [episodes] of season four — prove it to ourselves, to production, to the network — that it’s so easy that we’ll earn additional episodes,” Harmon said. “Because I never got this far [working on NBC’s] Community. I fell apart in season three of Community and got fired in season four. Now I’m about to do season four of Rick and Morty and want to prove that I’ve grown.”
