Summary
Theo narrates his reaction after discovering Kathy’s infidelity through her open laptop. He avoids her for days, feigning sleep and leaving early. Alone in the flat, he smokes a joint and tries to steady his nerves. While pouring wine, a glass slips, and he cuts his finger badly on a shard. As blood spreads, he thinks of Kathy—how he would normally turn to her for comfort. That door now seems closed. He spirals into self-loathing, cataloging negative thoughts about his worth and inevitability of betrayal. He reinterprets their entire relationship, seeing Kathy as a liar and himself as deceived. He recalls his childhood desire to die and thinks of calling his alcoholic mother, but realizes she cannot help him. Overwhelmed, he leaves the flat and walks aimlessly. His feet carry him unconsciously to the home of Ruth, his former therapist. After hesitating, he rings the bell. Ruth, now elderly and frail, opens the door with the chain on. Recognizing Theo’s distress and his bloodied hand, she lets him inside.

Study Questions and Answers
-
Why does Theo interpret Kathy’s open laptop as an unconscious invitation to discover her infidelity?
Theo believes that unconsciously, Kathy wanted him to find out. This reflects his tendency to read meaning into others’ actions and his need to see himself as a passive discoverer rather than an active confrontor. It also shows his psychological defence of rationalising her betrayal. -
What does Theo’s accidental self-harm reveal about his state of mind?
The cut symbolises his inability to keep control. He is physically and emotionally bleeding. The accident happens while he is intoxicated and attempting to numb himself, highlighting his dangerous coping mechanisms and the fragility of his composure. -
Why does Theo walk to Ruth’s house without intending to?
The unconscious journey suggests that, despite his anger and despair, he still seeks the safety of the therapeutic relationship. Ruth represents a stable, caring figure from his past. This demonstrates that his maladaptive patterns of relying on others are deeply ingrained.
