Deja, who has just started her medical residency, reveals at the get-together set up for saying goodbye to Rebecca that she's pregnant. In episode 17, the identity of the father of Deja's child is disclosed to be none other than her teenage sweetheart, Malik. Much to Randall's excitement, Deja reveals that she's having a boy, who she decides to name after Randall's biological father, William (Ron Cephas Jones). "Your grandson is gonna be named after a man I never met. But I know him. 'Cause I know you," Deja says as she shares the exciting news with Randall in an emotional moment in the series finale.
