Rick and Morty is known for frequently breaking the fourth wall, and story devices are often pointed out by Rick himself. Whether Rick and Morty season 7 will resume the show's tradition of annual anthology episodes is difficult to say.

Anthology episodes are a great plot device used to provide audiences with more details of a fictional world and its characters whether that's through flashbacks, flash-forwards, or just jumping between multiple narratives. Since the show's release in 2013, Rick and Morty has seen six anthology episodes, each layered with little details that add greatly to the lore of the show. Rick and Mortyhas seen several anthology episodes across its six seasons, jumping between multiple hilarious storylines all crammed into a twenty-two-minute episode.
