Question: In what episode does Henry Mills' biological mother help two children track down their father before they are placed in a foster care system?
Context: "True North" is the ninth episode of the first season of the American fairy tale/drama television series "Once Upon a Time".  The series takes place in the fictional seaside town of Storybrooke, Maine, in which the residents are actually characters from various fairy tales that were transported to the "real world" town by a powerful curse.  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.  Along the way, they encounter the Evil Queen (Lana Parrilla), and the Blind Witch (Emma Caulfield). The Foster Care Independence Act of 1999 (Pub.L.  106–169 , 113 Stat.  1882 , enacted  14, 1999 ) aims to assist youth aging out of foster care in the United States in obtaining and maintaining independent living skills.  Youth aging out of foster care, or transitioning out of the formal foster care system, are one of the most vulnerable and disadvantaged populations.  As youth age out of the foster care system at age 18, they are expected to become self-sufficient immediately, even though on average youth in the United States are not expected to reach self-sufficiency until age 26. Utah Foster Care (UFC), formerly "Utah Foster Care Foundation" is a non-profit organization that provides foster families for the State of Utah.  Since their founding, UFC has played a role in caring for young children who have been subjected to abuse, neglect, and other hardships by their caretakers.  As of 2013, at any given time in Utah, there are about 2,700 children experiencing crisis in the home who are in need of foster care.  Nearly half of all cases involve substance abuse by biological parents.  Given the difficult circumstances and special needs of these children, UFC's goal is to find and prepare foster parents to meet those needs.  They accomplish this goal by finding, educating, and nurturing families willing to open their homes to children in foster care. Congregate care is a placement setting that consists of 24-hour supervision for children in highly structured settings such as group homes, childcare institutions, residential treatment facilities, or maternity homes.  Such settings must be a licensed or approved home or facility that can take in 7-12 children, as seen in group homes, or 12 or more children, as seen in institutions.  Fourteen is the average age of children who enter into congregate care.  In the United States out of the 400,000 children in the foster care system around 55,000 live in congregate care settings.  In the United States in 2013 there was 55,916 children in congregate care.  In the last ten years, there has been a 37% decrease in the number of children in congregate care, which is greater than the overall 21% drop in number of children in the foster care system.

Debbe Magnusen (born January 6, 1956 in Pasadena, California), in July 1994, founded the Non-Profit Organization Project Cuddle based out of Costa Mesa, California.  Magnusen was a foster mother to over 30 drug-exposed children, while raising two biological children.  Five of those children were eventually adopted by Magnusen and her family.  She is the author of the non-fiction books "Don’t Abandon Your Baby" and "It’s Never Dull!!" .  "Don't Abandon Your Baby" tells the stories of babies who were nearly abandoned, but saved through working with Magnusen and her non-profit organization Project Cuddle.  "It's Never Dull" talks about true stories of drug exposed babies and how to care for them, as well as several insights into the foster care system. Rachel M. 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.  Rachel Ewald has also written a set of transition guidelines "Healthy Children, Healthy Adults" for foster care and adoption, with the intent of reducing disruption and trauma in foster and adoptive home and when reunifying children with their biological families. Kinship care is the raising of children by grandparents, other extended family members, and adults with whom they have a close family-like relationship such as godparents and close family friends because biological parents are unable to do so for whatever reason.  Legal custody of a child may or may not be involved, and the child may be related by blood, marriage, or adoption.  This arrangement is also known as "kincare" or "relative care."  Kinship placement may reduce the number of home placements children experience; allow children to maintain connections to communities, schools, and family members; and increase the likelihood of eventual reunification with birth parents.  It is less costly to taxpayers than formal foster care and keeps many children out of the foster care system.

Morrison described her character at the beginning of the first season as "broken, damaged and worldly".  During the fourth season finale, "Operation Mongoose", Emma absorbs the power of the Dark One into herself to save Storybrooke.  In order to successfully create a dark version of Emma, Morrison explained that "In order to build Dark Emma, I've been doing a bunch of research there with some of their mythology books and old fairy tale books and just looking back through the history of swans and the etymology of 'Swan'" and explained that Emma's rate of evolution "challenged [her] on a daily basis".  Emma became the primary antagonist of the fifth season's first half, until the end of the season's eighth episode when her real plans are revealed. On National Adoption Day courts and communities in the United States come together to finalize thousands of adoptions of children from foster care.  More than 300 events are held each year on the Saturday before Thanksgiving in November, in all 50 US states, the District of Columbia and Puerto Rico to finalize the adoptions of children in foster care.  In total, more than 40,000 children have been adopted from foster care on National Adoption Day.
