The third season of this fantasy series is made up of two big adventures, the first being a trek through the dark and dangerous forests of Neverland to rescue Henry (Jared Gilmore) from the clutches of a nefarious Peter Pan (Robbie Kay). Along the way, one character reunites with a long-lost family member, and David (Josh Dallas) fights for his life after being exposed to a poisonous plant. After a brief stop in modern-day New York City, the second big adventure takes place in Storybrooke, which is visited by Zelena (Rebecca Mader), the Wicked Witch of the West. She initially pretends to be a kindly midwife who's new in town, but she really wants to cast a curse to take down Regina (Lana Parrilla). Characters making their first appearances this season include Ariel (JoAnna Garcia Swisher), Tinker Bell (Rose McIver) and Rapunzel (Alexandra Metz).
