Catherine’s Grandson’s School Prank Fire Extinguisher

The extinguisher symbolizes the unpredictability of her emotional state: what should be a minor disciplinary issue becomes a metaphor for her fear of losing control, both over Ryan and her own violent impulses. Its mention is brief but loaded, tying her grandmotherly frustration to her broader trauma.
