After snatching the Underworld's "Bad Book" from Grim, Billy is overtaken by a malevolent spirit. In his chaos, he pilfers Grim's scythe and uses it to create a portal to summon Yog-Sothoth. Seeing the turmoil, Mandy calls upon Hoss Delgado to confront Billy. They discover that the only way to close the portal is by tossing the book inside. As Billy devours the book, Mandy pushes him into the portal, restoring order. Moments later, another portal opens, and Billy emerges, grumbling that they didn’t want him there.
