Scott drags Rachel along the stairs and she starts to bleed. He also discovers that she has been going to Kamal Abdic and doesn't believe her when she tells him that she was trying to help. Scott discovers that Rachel has been lying to him all this time - she wasn't a friend of Megan and she had never gone to her gallery. Scott and Rachel continue to meet and even engage in sexual intercourse, which causes them both to feel confused and angry. The police release news that Megan is dead and, days later, that she was pregnant. Kamal tells her that memories cannot be recovered however, a person who has lost a memory can often remember glimpses by going back to the scene where everything happened. Rachel decides to go to the therapist, Kamal, to see if he can recover her memory, and to try to find any information that will make him a suspect again. She remembers being in the underpass near the train station and her head and hands bleeding. As time passes, she remembers tiny details like falling on the stairs and a red-haired man helping her out. On the day Megan went missing, Rachel remembers that she was by where they live, but she doesn't remember what happened because she was heavily drunk.

Scott and Rachel still suspect Kamal though and believe he had a sexual motive. When they checked his house, there was no trace of Megan in Kamal's bedroom. Later, Kamal is held as a suspect, but set free because of insufficient evidence. When she sees a picture of Kamal Abdic, Megan's therapist, she says he is the man she saw with Megan. He asks her if she can identify the man based on a picture and she says yes. When they meet, she tells him about what she saw. Scott answers her email and ask her to call him. She also goes to the police station and tells them about what she saw, but they end up refusing her evidence because she was drunk the night that Megan disappeared. Unable to keep it to herself, she tries to get in contact with Jason, or Scott, to tell him what she saw. From the address on the newspaper, she knows that Megan is Jess and recalls the moment she saw her kissing the man.

The next day, she hears the news of a woman named Megan Hipwell who went missing. Rachel is sure it isn't Jason because this man was much taller and had a different body structure. She loves this house because it reminds her of her past, perfect life, before she and Tom divorced. She names the people in it, Jess and Jason.

However, there is one house that she cannot wait to see each day. Every day, she takes the same morning and evening trains, observing the same suburban houses by the tracks. Rachel lives with her university friend, Cathy, after she broke up with her husband and had no where to live.
