This isn’t your grandmother’s… er, Granny’s, as becomes evident when ABC’s Once Upon a Time sets foot in the Underworld.

In the midseason premiere “Souls of the Departed” (airing Sunday at 8/7c), Emma, Regina et al promptly spread out upon arriving in the ruinous realm’s topsy-turvy version of Storybrooke, in search of freshly deceased Hook. Snow White (played by Ginnifer Goodwin) handles the recon of Granny’s diner, which in the Underworld features a skeletal line cook and the Blind Witch (again played by Buffy alum Emma Caulfield) as proprietor.

The Blind Witch sniffs out the presence of the Enchanted Forest’s bandit-turned-princess, then gets the 411 on her mission. From there, yada yada… and then Rumple shows up to make a pronouncement about his role in this search-and-rescue.

Elsewhere in the episode, Regina reunites with her mother Cora, setting the stage for quite the emotional roller coaster, while in flashback we RSVP for the Evil Queen’s birthday, where she is the recipient of a most unexpected gift.
