Plot

Grim, Billy, Harold, and Mandy go to CostMo. Mandy and Grim notice something different, Costmo is usually crowded and full of Chaos now it's the opposite. Just then Hoss Delgado crashes through the roof. Hoss says it was on his list (which it was) suddenly the shattered glass go back to the ceiling and repairs it self.

Meanwhile, Billy meets up with Irwin and the same thing happens to them when the balls they let out go back inside the cage. They go inside a mayonnaise jar where they "moisturize" their skin. Hoss mistakes them for ghosts and fires at them before Mandy stops him. The same thing happens again.

Hoss explains that when he and Eris started dating, her life went orderly, his went too. Eris has also been ruining his life too; by redecorating his room, destroying his old photos, organizing his socks, and tampering with his wardrobe. Mandy points out that Hoss needs to break up with Eris if he wants his old life back, but Hoss admits that he's afraid to do so, pointing out how Eris might not take it well and that she "gets really freaky" when she's mad.

Grim offers to break up with Eris for Hoss while he goes to hide out in Aisle 5, but Eris turns into a demon and scares Grim. Mandy also tries, this time by imitating two gossiping women talking about they saw Hoss flirting with an attractive redhead in Aisle 5. But seeing her mad makes Hoss love her more, Eris apologizes before transforming into a bug and eating Hoss again. Hoss gives up, but Mandy won't allow it.

Irwin and Billy (poorly) disguise themselves as a grown man to distract Eris only for them to ruin it. Eris levitates Billy by asking him what he up to. Billy tells her what's going on which prompts her to shrink him into a small colony of Billys. Eris yells for Hoss and flirting won't work this time. Hoss finally confesses about wanting to break up with Eris, for a couple of reasons:

  • 1.) He wants his old life and be able to fight monsters again.
  • 2.) Eris isn't the same "crazy, goddess [he] fell in love with. [She's], like, normal."

Angered by the last comment he made, Eris turns into a giant bug and eats Hoss again.

Trivia

  • The store, CostMo, is a parody of Costco.
  • This episode marks Eris's final appearance in the series (other than her cameo in Grim's flashback in Wrath of the Spider Queen) before eventually returning in the unmade Underfist series, in which she splits into two different versions of herself, Nice Eris and Naughty Eris, as a result from being heartbroken from her breakup with Hoss.
    • On the subject of that matter, in Underfist, Hoss is said to have fallen into depression after the break up. This contradicts his other appearances after the breakup, as he was perfectly okay with it.
