'Rick and Morty' Season 4's Ten Episodes Have A Serial Story (And Meeseeks)

Despite early rumors that Season 4 of Rick and Morty might include more episodes than previous seasons, co-creator Justin Roiland confirmed to Entertainment Weekly the upcoming season will run with the standard 10 episodes. But while the season format hasn't changed, the new episodes of Rick and Morty introduce a compelling new narrative dimension: seriality.

"Without giving anything away, we have serialized stuff we check in on now and then that's sprinkled over the top of strong episodic episodes," Roiland told ET. "Fans of the show, they're going to want to watch them in order."

ET attempted to press Roiland on what the episodic storyline might be and got only this response: "I would definitely say watch all of Season 3 before Season 4."

Possible serial storytelling opportunities from Season 3 episodes include Rick's feud with the President of the United States, Beth's potential clone double, Risotto Groupon's anti-Rick militia and the resurgence of the Gromflomite-run galactic government. The powerful superhero-turned-murderer Supernova, from the episode "Vindicators 3: The Return of Worldender," also remains at large (the appearance of robot-crocodile hybrids in the first images released from Season 4 also suggest the Vindicators may be back). But most fans are likely anticipating a return to the Citadel, where Evil Morty has become president and assumed dictatorial power. For now, Harmon and Roiland aren't telling.

"There's going to be a couple Meeseeks popping up here and there," co-creator Dan Harmon said in the same interview, offering one of the few specific details available about the ten new episodes.

Both Rick and Morty creators are optimistic about the future of the series, even beyond the 70 renewal order, negotiations for which delayed Season 4.

"On any given day you'll feel like this thing can go for 20, 30 seasons. We have characters that don't really age, it's very Simpsons-esque. There's so much we can do to keep riding this train," Roiland told ET. "Unless people don't give a shit anymore. If we're making it and nobody's watching it..."

Work on Season 5 of Rick and Morty is already underway. "I think it's safe to say, without fear of being wrong, that the gap between Seasons 3 and 4 will be the longest and last time that it's ever so long that it's ridiculous," Harmon said. "There were so many things that had to be settled before we even started Season 4, and it's really safe to say—as Justin says—we're literally writing Season 5 while finishing Season 4, just to force ourselves to commit to a certain schedule."

"Every single season there's a little bit of anxiety: Now what's our definition of having fun and being good? Are we going to continue to be difficult on ourselves because that seems to be an ingredient in the quality? It's our job to relax and be happy—because that's another huge ingredient," Harmon said. "It's just weird when your job is to continue churning out something that you are proud of for its scarcity."

"We want every episode to be good. There are times we're like 'Okay, this one will be the worst of the season,' and we're still compelled to do everything in our power to fix what we think is wrong with it," Roiland said. "This season's been good. Pretty excited about this season."

Guest voices for Rick and Morty Season 4 include Paul Giamatti, Sam Neill, Taika Waititi and Kathleen Turner. The new season is expected to premiere in November.
