20. Skin Deep

Tess Pratt lets go of her son Andrew's hand for just a moment at the marketplace, but that's all it takes for the six-year-old boy to disappear. After learning that her father-in-law, Joseph, is a well-known white supremacist who was less than thrilled that grandson was interracial, the team initially focuses their suspicion on him, but despite his beliefs, Pratt is adamant that he would never harm his grandson. Vivian tries to keep the young mother calm, and the team hopes to get a lead when they finally get a ransom demand.
