His former mentor Betty Dean is the only person who can help discover their whereabouts, and they visit him for guidance despite Dean having tried to kill Namor. Descending into the Marianas Trench, they discover the predators dying out and desperately trying to feed their children in the remnants of an Atlantean craft. They save the captives, and Namor reluctantly causes the Trench's extinction to prevent further loss of human life.The Navy discovers an ancient blue box aboard the craft, and Atlantean soldiers assault their base to take it back. Namor strands himself in the desert takes their aircraft down during escape, and receives a centuries-old warning from the device before getting rescued.
Later, Namor and Lady Dorma visit Dean once more to ask her about who sank Atlantis, when suddenly, Thomas Holloway, an old friend of Namor's, attacks Dean.

Namor and Thomas decide to warn the Others, but they are suddenly attacked by Attuma's henchmen. After defeating Attuma's hunters, Namor and Thimas teleport to Germany, where Another, the Prisoner-of-War, is located.
