Rick unfreezes time, but since he, Morty and Summer have been living for so long on frozen time, a parallel dimension develops. The episode opens with time still frozen from the ending of Season One. Outside of the Smith Residence , Morty and Summer finish up some last minute cleaning duties while Jerry and Beth are still frozen outside. It's revealed that time has been frozen for nearly six months. Before Rick unfreezes time, he admits that 'their' time may need time to stabilize back within the 'world's time'.
The title of the episode is a pun to the novel, A Wrinkle in Time. In the episode, Rick, Morty, and his sister Summer—having restarted time after freezing it in the season one finale "Ricksy Business"—are in a quantum-uncertain state of existence. An argument leads to the creation of two alternate timelines, which need to be stitched back together fast if they are to escape quantum collapse.
