Soft on the Surface, Ruthless Beneath - Episode 8

At a household gathering Vivian Hooper declares she is the only heiress to Hooper Group and says she and Wendy were switched at birth. Her claim turns everyone against Wendy, labeled a foster girl who has lived as Vivian for years. Guests demand Wendy show the car key Jadyn gave the heiress. Wendy says she didn't bring it—the driver did—and can't start the car. Vivian accuses her of using a fake key and challenges her to prove it. The episode ends when someone checks and gasps, "It's really Vivian's car?", leaving the dispute unresolved.
