Lena is Stef’s lesbian partner and the “other mother” of their three children, two of whom have been adopted from the foster system. The vice principal of a local charter school, Lena is an altruistic activist who would love to save all the unloved kids in the world, and give them the support every kid deserves. When she violates her agreement with Stef and brings the needy Callie home for a “temporary” stay, she defends her decision. But when Callie disappears with their older son, Brandon, in tow, both Lena and Stef fear that Lena’s soft-heartedness may have given rise to big problems.
