To Eris Human is the third segment of the tenth episode of Grim & Evil.


While Billy "grocery shops" for socks at the Endsville Mall, Grim spots Eris, the Goddess of Discord and Chaos. Grim has a crush on her, but Eris doesn't like him and would rather go out with a guy named Adonis.

Mandy and Eris play various pranks on people, until Eris plays a prank on Mandy (claiming "Everyone's a target"). Naturally, this makes Mandy mad and she wants to get back at Eris.

Later, after Billy's done "grocery shopping," he teases Grim about his crush on Eris, which gives Mandy an idea: she goes up to Eris and tells her that Adonis wants to meet her at the mall's movie theater. Eris goes to the theater, which is dark inside, and she sees a silhoulette that she assumes is Adonis. She goes up to him and kisses him on the cheek. But after Mandy turns the lights in the theater on, it turns that the guy Eris is kissing is actually Grim, which, naturally, she's horrified/humiliated by.

Mandy's glad to have gotten back at Eris, and Grim's happy that Eris finally kissed him. Billy had watched the exchange, and he complains that "kissing is gross," but then he offers Mandy and Grim a "hot buttered sweat sock."

  • This is the first appearance of Eris.
  • The title name of the episode is a pun of "To Err is Human".
  • Eris starts off with a Valley Girl accent and is depicted as a stereotypical "dumb blonde" in her first appearance. After running off with Mandy to spread chaos, her voice switches to an eloquent British/Transatlantic accent and her true intelligence is revealed (and she remains that way for the rest of the franchise).
  • This is the only episode where Grim's shown to be romantically interested in Eris; after this episode, he seems to have gotten over his crush on her.
  • Grim's never been to a shopping mall before this episode; he had "mall" confused with "maul," which means "(of an animal) wound (a person or animal) by scratching and tearing."
  • Eris does not have gapped teeth in this episode.
