Charlotte and Nicola toe the line between intimacy and distance. Though they live together and even sleep in the same bed, the bounds of their relationship are, for the moment, rigid—they’re not ready to enact any physical intimacy except when necessary (that is, when Charlotte’s flames are out of control). Their comments about their family members, which mostly involve themes of loss and detachment, suggest that Nicola and Charlotte are both aware of how emotional attachment can cause pain, which perhaps explains why they’re hesitant to let their relationship become more serious.
