If you look closely to the Movie Night picture in Willow's scrapbook you can see they're watching Hocus Pocus (1993)
This is the only episode to not take place in the Demon Realm, as well as the only episode to take place completely in the Human Realm.
Throughout the episode, Luz never interacts with Willow, Gus, and Vee, only with, Amity, Camilla, and Hunter.
