S2E6: The Ricks Must Be Crazy

In "Rick and Morty" Season 2, Episode 6, things wrap up with the Smith family dealing with some serious parasite problems. The house is overrun with parasites that implant false memories into their victims, creating new characters who all seem like they've been part of the family forever. The only way to identify the parasites is by focusing on memories associated with negative emotions since parasites can't create those. Rick, Morty, and Summer, along with Beth and Jerry, start picking off the fake characters one by one. The turning point comes when Morty realizes that Mr. Poopybutthole, a character they all thought was real, might actually be a parasite. Beth shoots him in a moment of panic, only to discover he was real all along—oops. The episode ends with Mr. Poopybutthole recovering in the hospital, while Beth grapples with guilt over shooting him. Meanwhile, the rest of the family tries to process the chaos they just survived. As a nice touch of dark humor, Mr. Poopybutthole's doctor gives Beth a prescription for her nerves—because nothing says "sorry for shooting you" quite like some meds.
