“Why can you talk?”

The A-plot of episode four, “Claw and Hoarder: Special Ricktim’s Morty,” follows the adventures of Rick, Morty, and Summer as they attempt to rescue Morty’s “slut dragon,” Balthromaw, from an evil wizard. Elsewhere, though, Jerry befriends an apparently mild-mannered talking cat (voiced by Matthew Broderick) who turns out to be completely manipulative and obnoxious. Curious about the origins of this Florida-obsessed feline—and more specifically, why he can talk—Rick scans his mind to reveal… something so horrible the viewer is left to imagine the absolute worst, based on the reactions of Rick, who contemplates suicide, and Jerry, who barfs, then collapses in a quivering heap until Rick erases the memory of whatever terror he’s just witnessed. (Something like the “hell dimension” from Event Horizon feels like a decent guess?)
