Calculator had their plane bugged and heard the whole plan. Weather Wizard was waiting for them, and no cargo was in the hold. Catman went on the attack while the rest of the Six retreated. The Six were hugely outnumbered and were captured. Catman woke up on the operating table of the Crime Doctor.
