Ethan finally woke up and desperately chased them back, only to find the two had found warmth and reliability with Thomas, a gentle auto mechanic. Thirteen years later, Lily grows up with a happy family. Ethan realizes belated remorse can never heal past wounds and leaves alone in eternal loneliness.
