Sylvia Steinetz

Sylvia Steinetz is one of Grace Fraser's oldest friends, part of the tight, moneyed circle of parents at their children's exclusive private school. She sits on the fundraising committee, trades knowing looks and gossip, and moves through this polished world with the easy confidence of someone who has always belonged in it.

Lily Rabe gives Sylvia a brittle, watchful warmth that makes her feel like a real friend rather than scenery, someone whose loyalty seems solid until the story starts testing what these women actually owe each other. She's a study in how comfortably cruelty and concern can share a face in this milieu.
