Hearken back to earlier lines in the poem, and recall how Circe tells Odysseus that she changed his men into swine in order to show him her "goodness" and her "power." She's like a double-sided coin, heads or tails. In this moment, we see another kind of coin appear – that of Circe's ability to see two very different things. She sees both her happiness and her unhappiness. She sees both her and Odysseus living together, and she sees them split apart.
