Eight years later, everyone is celebrating Lucy's birthday when Gothel appears with her coven of witches, freeing Drizella. With the curse looming, Regina heads off to get help from Zelena. Later, when the heroes confront the witches, Gothel reveals that they have poisoned Henry and Regina is forced to cast Drizella's curse in order to save his life. In the present day, Regina locates a cursed Zelena in San Francisco, who now goes by Kelly.
