Missy Sayers

Missy Sayers moves through Easttown's teenage world as one of Erin McMenamin's peers, present at the parties and hangouts that ripple outward once Erin is found dead. She's watchful and a little guarded, the kind of witness whose offhand comments carry more weight than she seems to realize.

Sasha Frolova plays Missy with the low-key naturalism the show demands of its younger cast, never overplaying a scene meant to feel like ordinary teenage life curdling under scrutiny. The character works as a small, credible thread in a town where everyone's testimony matters and no one is quite telling the whole truth.
