In the Land of Oz, Zelena banishes Glinda the Good Witch of the South to the Enchanted Forest. In this new realm, she begins living in the Dark Forest, north of Rumplestiltskin's castle, hidden in a pocket dimension of ice and snow, which only those who are pure of heart may enter through. ("A Curious Thing", "Kansas")
Regina, Snow White and Prince Charming gain information from Rumplestiltskin about Glinda, the Good Witch of the South, who can help them defeat Zelena. They travel to the edge of the Dark Forest, where they find a door amidst the path. Charming examines the door, which seems to lead to nowhere. Knowing that the door can only be accessed by the pure of heart, Snow White steps through it and disappears. When Charming follows her through the door, Regina concludes that it must be a cloaking spell and tries to step though the door as well, only to enter the path behind the door. Realizing she is not allowed to go through the door, the Queen briskly walks away.
Sensing the incoming presence of Snow White and Prince Charming crossing into her realm, Glinda makes herself known to them. When Charming asks for Regina's whereabouts since she was just with them, the witch says that she can't come through because her heart is heavy with vengeance. The banished Good Witch briefly explains her past friendship with Zelena and reveals that she is not powerful enough to defeat her, but Zelena's own power is contained within the green pendant she wears on her neck. She tells them that only a purveyor of the greatest light magic is capable of defeating Zelena and removing the pendant. Recalling that her own daughter, Emma, is a product of the strongest magic of all — true love, Snow White believes she may able to defeat Zelena. Glinda agrees with this sentiment; further prompting Snow White to go through with casting another Dark Curse to send everyone back to Storybrooke. ("A Curious Thing")
- The Dark Forest, where the entrance to Glinda's winter garden is located, is mentioned on Sir Maurice's map in "Skin Deep". ("A Curious Thing")
- The door leading out of Glinda's winter garden is the same as the door conjured by the Apprentice in "Operation Mongoose Part 1", and the door created by Zelena in "Only You". ("A Curious Thing")
