Rebecca Harkness

Rebecca is one of the private-school mothers orbiting Grace Sutton's world, a fixture at fundraisers and pickup lines who trades in gossip and social standing. She's quick with an opinion, alert to any crack in her friends' polished lives, and eager to be at the center of whatever drama unfolds.

Tracee Chimo plays her with a brittle, watchful energy that turns background chatter into something faintly predatory. She's a comic pressure valve in a story about wealth and denial, but the performance never lets you forget how much cruelty hides inside casual concern among people who call themselves friends.
