he Ricklantis Mixup starts off with what seems to be a normal Rick and Morty adventure, but then it swerves us and instead gives us a peek into what happened to the citadel of Ricks and some short stories about what's happening there, with an election going on to become president where it's mostly Ricks and one Morty running.
The first story is about a group of Mortys being stuck in some sort of school, hoping a Rick would pick them as a replacement, but deciding to find a way out of the citadel, eventually leading them to a "magical portal" out, only one out of the group actually decide to jump down it, which is later revealed to be a garbage dumb, likely to a star.
The second story is about a new Rick cop and a jaded Morty police officer, they both track down a bunch of Morties who stole from a store, the Cop duo head to in Morty town, a run down area of the citadel filled with Mortys without any Ricks, to find a local crime boss to learn the location of the gang that did it, they finally find them and arrest them but Rick gets arrested for breaking regulations.
The last story is about the politian Morty, who's against the Ricks to become president and after some convincing retoric and an attempted assassination, is able to convince people to vote him into power and starts some major changes, first with killing all who disagree with him and revealing himself to be evil Morty from season 1. Overall this episode is good and shows the aftereffects from the first episode of this season.
