The Mother-in-Law

In a flashback, a newly pregnant Lucy calls Diana three months after the Christmas incident to ask for Diana’s help with the children. She does not reveal her pregnancy to Diana and lies about feeling ill. Diana instantly agrees and picks up the children for a sleepover at her home. Lucy warns her to be careful with the dangerous stairs and the pool at Diana’s home and forgets to say thank you as Diana and her children rush out the door. After they leave, Lucy sleeps peacefully. Early in the evening, Lucy receives a call from Diana, informing her that she must meet them at the hospital.

In the present, Eamon and Ollie’s fight breaks up quickly. He storms off to his office. After occupying the children, Lucy confronts him. When Ollie apologizes instantly, Lucy wonders if he is apologizing for murdering Diana. Ollie reveals that they are in serious debt because of the business and that he hoped his inheritance would allow him to pay off their debts and leave the business. Lucy comforts him.

Diana recalls what happened with the children. She prepares to swim with Archie in the pool and asks Tom to watch Harriet. She notices that Tom is acting strangely.
