As the temperature rises to , the two women grow weaker. Norma burns her hand on a windowsill. Mrs. Bronson becomes psychologically unstable, beseeching Norma to paint a picture of a cool subject, rather than Norma's usual paintings of the sun and burning cities, screaming, "Don't paint the sun anymore!". A looter enters the building through the roof access door, which Mrs. Bronson neglected to lock. They hide in Norma's apartment. The looter calls from outside, demanding entry. Norma threatens him with a cocked revolver, and they hear him walk away. Against Norma's pleas, Mrs. Bronson unlocks the door, and the stranger forces his way in, pulls the revolver from Norma and drinks their water. He calms down after seeing their distress and begs for their forgiveness, claiming that he is an honest man driven insane by the heat. He throws away the revolver and describes the recent death of his wife and newborn child. He begs for forgiveness until Norma acknowledges him with a nod; he then leaves the apartment building.
