Carl stayed in his first story apartment.

Carl stayed in his first story apartment. Eventually, he became rich and could buy anything he wanted. But no matter how hard Carl tried to lie to himself, the loss of his family ruined him. He missed Anna's nagging, Patrick's juvenile maximalism, and Martha's happy laughter. The walls of Carl's apartment caved in on him, trapping him under the monstrous weight of his memories and guilt, and he remained depressed and suicidal until the end of his days.
