Over the following days, Cass continues to receive what she refers to as silent calls. Not wanting to spend another night home alone, she takes Matthew’s suggestion to book a hotel room. He’ll join her there on Friday when he returns from his business trip. Cass is at the hotel when Rachel texts about the plan for her to stay the night at Cass’s house, a plan Cass had forgotten. She invites Rachel to come to the hotel instead, but Rachel says it’s too far away. Cass decides to confide her fears about her memory to her friend, but Rachel hangs up too fast.

On Friday, Matthew tells Cass that someone from the alarm company was at the house when he got home, with a contract to install an alarm that has Cass’s signature. He found a client copy inside the house, filled out in Cass’s handwriting. She concedes that she must have agreed to it without full awareness since she was so eager for the alarm representative to leave. Cass and Matthew decide to have the alarm system installed rather than try to get the contract voided. Matthew leaves the hotel early the next morning to be at the house when they install the system.
