Lana Parrilla and Rose McIver

ABC's Once Upon a Time will add a little pixie dust this season when Kiwi actress Rose McIver debuts as Peter Pan sidekick Tinker Bell in the third episode. "Our Tink is very strong, a lot of fun and not afraid to go out and have a few shots," says executive producer Edward Kitsis. "And although her heart is usually in the right place, she is mischievous."

McIver, 25, says her "glamorous" Tink comes with a magic wand — and a mysterious past. "Captain Hook has a history with Tink and wants to find her to help lead the team to Peter Pan's camp," says the actress, whose wings are added digitally in postproduction. Viewers will see Tinker Bell in different stages of her life, including during interactions with the Blue Fairy and the Evil Queen, says exec producer Adam Horowitz. "Tink has gone through an evolution in our story. She begins in one place and ends in another."
