Once Upon a Time - Season 3 - Eps 19: A Curious Thing
Zelena threatens to kill Henry if Hook - whose lips have been cursed by the Wicked Witch -- doesn't proceed with kissing Emma, which will drain all of her magical powers away, and things begin to heat up between Regina and Robin Hood. Meanwhile, back in the Fairy Tale Land that was during the past year, Snow and Charming go in search of Glinda, The Good Witch of the South, to see if she can help them defeat Zelena, and the curse that will ultimately send the Fairy Tale characters back to Storybrooke is cast -- but from an unlikely source.

Synopsis
There is a town in Maine where every story book character you've ever known is trapped between two worlds, victims of a powerful curse. Only one knows the truth and only one can break the spell. Emma Swan is a 28-year-old bail bonds collector who has been supporting herself since she was abandoned as a baby. Things change for her when her son Henry, whom she abandoned years ago, finds her and asks for her help explaining that she is from a different world where she is Snow White's missing daughter.
