Cap swims to the dock and apprehends his enemy, the Water Wizard. The frightened baddie, who had asked to meet Cap there, confesses it was a test to make sure he was the authentic Captain America. WW then takes Cap out to the Bar with No Name to show him the bodies of the 18 costumed criminals slain by the Scourge of the Underworld last issue.
