In the end, Morty saves Jessica, but the experience has changed her. Having spent what felt like eons frozen in a time-stasis crystal in the other dimension, she has transcended human emotion. She tells Morty she just wants to be friends because she is now a "Time God."

Mr. Nimbus arrives at the Smith house, demanding a formal dinner to negotiate a new treaty. Rick, strangely intimidated by Nimbus (who "controls the police"), tasks Morty with a high-stakes chore: he must retrieve wine from a "Narnia-style" dimension where time moves at an accelerated rate. Rick needs the wine aged for decades, which takes only seconds in that world.

They have steampunk technology and "Wine-Guardians."

They are a medieval society dedicated to killing him.

Morty just wants his date with Jessica to go well, but he ends up accidentally genociding an entire timeline just to keep the wine flowing. Eventually, the portal-dwellers kidnap Jessica, pulling her into their world. The Conclusion

The episode ends with Rick getting arrested by the literal police (controlled by Nimbus), and Morty sitting on the roof, realizing that his desperate attempt to have a normal night resulted in the destruction of an entire civilization and his chances with his crush.

Morty enters the dimension to save her, and Rick eventually joins the fight after his dinner with Nimbus falls apart. Just as they are about to be overwhelmed by the futuristic tech of the "Narnia" world, Mr. Nimbus saves the day by controlling the water (and the police) to bail them out.
