In the Sentry's passage, one sees a governing metaphor in his speech when he compares Antigone to a bird. He compares her character and her emotional reaction to that of a distraught mother bird who comes home to an empty nest. The Sentry describes Antigone as a bird who has "come back to an empty nest, peering into its bed, and all the babies gone... Just so, when she sees the corpse bare she bursts into a long, shattering wail" (lines 470-475). This reflects Antigone's character in more than one ways. The bird represents her free spirit, and the comparison of coming back to an empty nest represents her family that seems to be disintegrating, and the pain she goes through while watching Polynices being stripped of his rights once again. The Sentry goes further to describe how they "closed on the kill like hunters" (line 481), the hunters being the Sentry's group and the kill symbolizing Antigone. This moment is significant in the way that her "shattering wail" gave way to her capture. It changes the strong woman Antigone was into a hopeless and desolate one who ends her own life. Her imprisonment also brings out the theme of choosing love over law or vice versa, where the following events bring out the true colors of each character, including Creon and Haemon. Haemon respects his father but he is also in love with his future bride Antigone, and he chooses his love over law.
