The Replacement: Season 1, Episode 2

1 - 2: Episode 2

Ellen tries to juggle her new baby with returning to work and investigating Paula.

She finds evidence that her boss was having an affair, but her only lead is Paula's 10 year-old daughter Caris, and Paula's former colleague, the mysterious Georgia, neither of whom want to speak to her.

Ian asks her to stop pushing, as her fixation is taking priority over Lia, her newborn baby.

Paula discovers Ellen's investigation and engineers a humiliating situation with a client and a warning visit from social services. Ellen eventually confronts Paula and forces her to confess what she's been hiding.
