However, she has a cleanliness mania due to which she does not want to touch a garbage bag. Her problem is who will put it outside on the garbage collection day, that was always done by Vivienne. She insists that Alex stays a few days so that he can do it. He agrees and also arranges the funeral. During his stay he visits and has sex with Maggie (Carrie-Anne Moss), a female neighbor who, he has been told, is a prostitute. He asks how much he owes her, but she is surprised, she did not do it for money. He is embarrassed, but also relieved, not only that she is not seriously offended by the insinuation, but also because he was not sure he had enough money with him. The police warns her to be careful, Alex has committed a murder and served a prison sentence for that. Nevertheless they continue to be friends and have sex. Maggie does not confront Alex about the matter, but later Alex confesses about the murder: he killed the man who caused the death of Alex\'s son in a car crash, on the day Alex was going to meet his son for the first time; Alex had only recently learned about his existence, the result of an affair a long time ago. Although Linda first tells Maggie she does not want any help from her, Maggie helps Linda anyway.
