Jess Riley

Jess Riley drifts around the edges of Easttown's murder case as a friend of Erin McMenamin, the dead girl at the center of the investigation. She's watchful and a little worn down, carrying secrets she isn't eager to hand over, and Mare's questions land on her like pressure she's used to absorbing quietly.

Ruby Cruz plays Jess with a guardedness that never tips into obvious deception — she's someone shaped by a town that already expects the worst of girls like her, and the performance lets you feel that exhaustion under the suspicion. It's a small role that earns real weight through restraint rather than melodrama.
