Arceus pours down the sea it's created in the sky, forming it into a dome of water around Heatran to contain it. Brock notes that unlike before, the meeting of fire and water isn't causing an explosion, which Cynthia explains as a demonstration of how Arceus's power can even overturn the laws of nature.
