"Don't mention it," the Gizl said, then leaped off to save others.
"He talked!" Alis said.
Don watched the Gizl make a mid-air grab and haul back a man who had looked as if he might otherwise have gone over the edge. "He certainly did."
"Then that must have been a masquerade, that other time—all that mumbo-jumbo with the Anagrams."
"It must have been, unless they learn awfully fast."
He and Alis clutched each other again as Superior tilted. It remained steady otherwise and they were able to see the ocean, whose surface was marked with splashes as a variety of loose objects fell into it. Don had a glimpse of Professor Garet's machine plummeting down in the midst of most of Superior's vehicular population.
"There's a plane!" Alis cried. "It's going after something on the surface."
"It's the Hustler," Don said. "It's after the submarine."
The B-58's long pod detached itself, became a guided missile and hit the submarine square in the middle. There was a whooshing explosion, the B-58 banked and disappeared from sight under Superior, and the sub went down.
