The woman is revealed to be Elizabeth Childs. Sarah steals Beth's identity, job, purse, and shoes. Sarah finds out that Beth has $ 70,000 dollars in the bank. This is enough for Sarah to disappear with her daughter, Kira, and her foster-brother, Felix. Beth turns out to be a police officer with a boyfriend, Paul. Sarah also finds out that a few months before, Beth had killed a civilian, Maggie Chen. Beth had been suspended from the force following this. When Sarah impersonates Beth, it is difficult to convince Art, Beth's police partner, that everything is fine.

Meanwhile, Felix arrives at the coroner's office and identifies Beth's body as Sarah.
