Callie Sadecki

Callie is Shauna's teenage daughter, restless and undersupervised, chafing against a mother she finds cold and a home life that feels airless. She lies easily, sneaks out, and courts trouble as a way of getting noticed, unaware of how much darkness her family is quietly sitting on.

Desjardins plays teenage recklessness as a mirror rather than a nuisance subplot — Callie's small deceptions echo her mother's much larger ones long before the show spells it out. She's believably bratty and believably lonely at once, which keeps her from ever feeling like filler.
