A pay day is coming. Over the first two seasons of The Righteous Gemstones, a consistent thorn in the side of the titular televangelist dynasty was their louche uncle, Baby Billy Freeman (Walton Goggins) — or, as Jesse Gemstone (Danny McBride) and siblings memorably refer to him, "Uncle Baby Billy." He's connected to the family through late matriarch Aimee-Leigh (Jennifer Nettles), whose death left Baby Billy out of sync with the children of Eli Gemstone (JohnGoodman).
