Zoq, Calliph of Callisto, finds a means of taking advantage of a trip through the asteroid belt for unmanned cargo vessels bearing methane shipments from Jupiter. He creates explosions to make it seem the ship has been destroyed by running afoul of an asteroid. The explosive devices he uses for the effect use "methazone". He hijacks the ship for sale on the black market. Given the run of the place, Rex and Speed take Kara prisoner, stashing her into an empty methane barrel after the gas renders her unconscious.
