Meanwhile, Caroline tells Mary all about the sado-masochistic relationship she has with Robert. Robert had soon started to become very violent towards her, especially when they were having sex. One time, he even broke her back while having intercourse, the reason for Caroline's enduring pain and limping. Caroline nevertheless points out that in a way, she enjoyed being hurt and loathed by her husband. Eventually, they even shared a mutual fantasy, namely to kill someone. Mary does not really comment on what she has just learned. Later on, Caroline makes some tea and leads Mary into her and Robert's bedroom. Mary is surprised to find a wall covered with photographs of Colin. As she slowly begins to understand what Caroline and Robert have in mind with Colin, she starts to feel very tired and falls asleep.
