Elsewhere Foxbat helps DEMON kidnap Dr. Arcane's daughter, but even Foxbat thinks that the Demon Master is nuts, so he drops a dime on them. Meanwhile, Rose and The Marksman fight of one of Malice's old henchman, and a DEMON detachment, to capture the third and final mystical gem of the Hellfire Crown.
