As Iquala orders the Tritonis army to eliminate the last bit of Atlantis's army who rush to meet their foes, much to Aquaman's horror. Aquaman then begins his battle with Iqula himself,defeating him.
Meanwhile at United Nations, they continue to discuss who shall become the ambassador for Poseidonis, with Aquaman being chosen due to his ability to survive outside of the ocean.
