Rick and Morty Season 4 Episode 7 - Promortyus Episode Title:Promortyus.Episode Description:Rick and Morty find out that they have been mind controlled by facehugging parasites called the Glorzo, and that they are attempting to use Rick's UFO to power a superweapon that will spread the Glorzo to Earth. Rick and Morty manage to fight their way off the planet, causing mass destruction. However, upon returning home, they realize they left Summer behind and return on a rescue mission, only to find that Summer does not have a Glorzo attached to her and is worshiped as a goddess. Summer explains that after Rick and Morty fell under the control of the Glorzo, she was spared due to a toothpick in her mouth, which prevented the Glorzo from being able to latch on to her face and caused them to consider her a goddess. The three of them attempt to escape, but are blocked by the rest of the Glorzo. Rick then uses a tune from Morty's harmonica, which triggers the Glorzo's host body to lay its implanted egg, resulting in the death of both the host and the controlling Glorzo. All of the Glorzos are killed, but not before accusing Rick, Morty, and Summer of destroying them simply for trying to advance their civilization. Upon returning home, Rick and Morty start feeling severe stomach pain. Fearing they're about to lay Glorzo eggs, the two say their final goodbyes to each other, but it turns out the pain was from a regular bowel movement.
