Sarah Parker

Sarah Parker was once Gretel but now is a citizen of Haven. She is an orphan along with her brother, Dave Parker.

Camelot(Pre-Exile)
Hansel and Gretel were supposedly abandoned by their father and found their way to a now-evil Rapunzel. They are almost eaten so that Rapunzel can use their innocence in a new spell that could bring Flynn Rider back to life but they escape and she is locked in the oven until she escapes with the others.

Haven
She is given the new name of Sarah Parker and later becomes friends with Eddie Grant. They help Rapunzel see the error of her ways and join the town of Haven. Unlike her brother, she joins Eddie's side at helping Lawrence Hall overcome the wolf inside of him and defeat his evil brother.
