In the season 7 finale, “Fear No Mort,”Mr. Poopybutthole, still heartbroken over his divorce, used a stolen portal gun to sneak into a universe where his family never left him. He switched places with his alternate self and infiltrated his home. His wife, Amy, was instantly shown to be suspicious of this new version of her husband.

The season 8 finale’s post-credits scene follows up on this development. AsMr. Poopybuttholecomments on the events of season 8, the camera pulls back to reveal thathe’s being held in a mysterious facility, monitored by scientists. This scene reveals that Amy has figured out her husband is an impostor and turned him over to the proper authorities.

Rick & Morty Suggests Mr. Poopybutthole Originated Outside The Central Finite Curve

His Atomic Vibrations Don’t Match This Reality

As the scientists monitor Mr. Poopybutthole and confirm that he’s not the version of Amy’s husband from this universe, they’re baffled by the readings on their machines. They tell Amy that his atomic vibrations don’t match anything in their reality. The choice of the word “reality” is interesting, because a reality might be different from a universe.

This could be nothing — it could just be a throwaway line confirming this Mr. Poopybutthole isn’t from the universe he says he is — or it could be setting up an interesting twist. It might be suggesting that Mr. Poopybutthole originated from outsidethe Central Finite Curve. Maybe he’s being set up as the villain ofRick and Mortyseason 9. He could even be the key to bringing back Diane.
