The Imagery of a Glass Wife (“Requiem for a Glass Heart”)

The Imagery of the Twin Brothers (“The Mark of Cain”)
Caleb and Jacob are indistinguishable; hence, outsiders would find it problematic to tell them apart. Their resemblance motivates them to perpetuate a triangle of deception that includes the narrator as they are assured that she would not distinguish them. However, the narrator makes a distinction between them based on how they treat and look at her.
