1 A Rickle in Time

Continuing from "Ricksy Business", Rick, Morty and Summer spend six months repairing the house and screwing around with time frozen. After unfreezing it, the trio ends up in a decaying dimension. They split into separate timelines whenever they are uncertain about something. Rick becomes paranoid, thinking that his duplicates want to kill him, but eventually he calms down. A creature in charge of safeguarding time appears and gives them collars that integrate all the timelines, then attempts to arrest them because Rick stole the time-freezing crystal. Rick, Morty, and Summer show uncertainty on purpose and break the collars, splitting into sixty-four timelines, and they simultaneously beat up the same creature. Rick then repairs the collars, and they successfully integrate all the timelines. In one timeline, Rick attempts to sacrifice himself and let Morty live by giving him his collar, but ultimately he survives too. Meanwhile, Beth and Jerry hit a deer, and bring it to an animal hospital. A hunter claims the deer for his own because he shot it before the accident. Beth is able to save the deer's life and release it. Post-credit scene: The creature and his friend beat up Albert Einstein, mistaking him for Rick. They tell him that he should not be messing with time, but this leads Einstein to spite them by devising the famous mass–energy equivalence equation, E=mc2.
