On the same day, Saturday, August 17, 2013, the memory of Tom's hitting her in the underpass triggers other memories—memories Rachel had before but discarded as false because they did not coincide with Tom's version of her blackouts. Knowing now that sensory experience helps recover lost memories, Rachel begins to trust the feelings she remembers. The fear she felt when cowering next to the golf club suggests that Tom swung it at her, not the other way around. Now trusting her feelings, she is sure that Tom hit her in the underpass, walked away from her to his car, and got in with a woman: Megan.
The rapidly alternating chapters create the impression of an unstoppable train racing toward its destination. On the day Anna recognizes the female voice on the phone, Rachel recognizes the woman who was in the underpass with Tom. Disclosing that she saw Megan with Tom that night, Rachel's perspective confirms the suspicions that have been mounting in the other perspectives.
Rachel also recovers memories from her marriage with Tom, realizing that Tom has been lying to her all along, manipulating her into believing that she was an angry and violent drunk, when actually, he was an angry and abusive husband. Armed with this knowledge Rachel can and must rewrite their history and revise what she thought to be the truth.
