In the episode, Sheriff Emma Swan (Jennifer Morrison) helps two children (Karley Scott Collins and Quinn Lord) track down their father before they are placed in a foster care system, in a parallel with the story of Hansel and Gretel.

Ewald is the founder and chairwoman of Foster Care Support Foundation, Inc.  The Foster Care Support Foundation FCSF is a 501(c)3 non-profit organization that provides clothing, equipment, and toys to at least 3000 foster and displaced children throughout the state of Georgia annually.  The services are free for those raised on basic state per-diem and for grandparents and relatives raising their grandchildren, nieces or nephews without the biological parent/s present in the home.  In 1996, Ewald began collecting and distributing clothing and toy donations from neighbors to give to local foster children in need.  The program and need grew quickly and the Foundation was incorporated in 2000.  Ewald, a foster parent herself of fourteen years to over 50 children and mother of four biological children, understood the difficulty of raising a child on fifty to seventy five cents per hour.  The center allows for more foster parents to afford to care for state children, while also allowing the children to acquire their own clothes, toys, and be much like any other child after losing everything when pulled from their biological homes.  The organization's donation/distribution center, located at 115 Mansell Place in Roswell GA is set up like a retail store and is fully stocked with clothing, toys, bikes, highchairs, and other necessities, where foster parents throughout the state can come, by appointment, and shop for free.
