Unbeknownst to all, Belinda is Jacob's sister. She kept this secret to prevent potential parents from breaking up siblings because they see her as "too old" to adopt. With Jacob secured in a home nearby, Belinda can figure out a way for them to flee; she believes that their father had given them up for adoption with the full intention of reuniting with them in the near future. She is so sure of this that she resists family life within the loving embrace of Missie, the Davises, Zach, and the community; she sneaks out of Missie's home nightly to reassure Jacob that soon they will leave together. She becomes more determined after learning that the Pettises beat and starve him.
