St. Equis Hospital is a horse hospital where Beth works. Davin worked there with Beth. Jerry was incredibly jealous and suspicious of Davin. In "Rick Potion No. 9" Davin made overt sexual advances to Beth when he suddenly caught the "Morty love bug" and shortly thereafter turned into a "Mantis-person" as a result of Rick's first attempt to cure the illness. Jerry then burst into the room and beat Mantis-Davin to death with a crowbar, saving Beth in the process.
