He thought he was smarter than everyone else. He is Sauron in the guise of Halbrand. But now he's sitting next to a woman who's crying because she's pregnant with his child. Metamorphosis, the reverse transformation of the forces of evil. He hadn't planned this. His plans were enslavement, power, and the creation of an ideal order where everyone obeys his will. And now? Now he's bound hand and foot by a little creature that hasn't even been born yet.
He remembers how cynically he wove a web of lies, how he played with other people's lives to achieve his goal. And so, ironically, he himself got caught in a net woven of love, pity and, perhaps, sincere affection. He sees her tears, feels her fear and helplessness. And for the first time in millennia, he feels something like remorse.
He looks at his hands, the hands that held entire nations in awe, the hands that could crush mountains. Now those hands don't seem to know how to comfort a crying woman. Sauron, the great and terrible, proved powerless before the simple human drama. He lost before he could start the war. And now he has to accept his new role – the role of a father. A role for which he is completely unprepared.
