Grace Peyton

Grace is Jackie Peyton's daughter, a watchful, anxious kid navigating the ordinary terrors of school and growing up while her mother works brutal hospital shifts. She's sensitive to a fault, prone to worry and ritual, and quick to notice the tension in her house even when nobody explains it to her.

Ruby Jerins plays childhood nervousness without cutesiness, giving Grace a watchfulness that feels earned rather than written-in. She works as a quiet pressure gauge for the Peyton household: her small anxieties mirror the much larger ones her mother is hiding, and the show trusts a child actor to carry that weight honestly.
