Cedar and Little Mary’s grandmother and Mary Potts Almost Senior’s mother, who is over a hundred years old. She is the only member of Cedar’s birth family that Cedar initially warms to. With an old, wise, and comforting presence, Mary Potts the Very Senior is the one to let Cedar know that miscarriages are genetically passed down through the family, suggesting that Cedar does, in fact, have a high-risk pregnancy. The old woman’s relationship to her family is both affectionate and distant; she doesn’t seem to know about her granddaughter Little Mary’s drug problem and seems interested, but relatively uninvested, in Cedar’s sudden reappearance. At her age, she is on the precipice of death, after all, and seems to navigate family relationships with accordant detachment.
