It's a long-standing tradition in the franchise that flashbacks based on the word of a single character can turn out to be completely false. See also Cowpoked.
John Rozum contributes a fair play foray in "The Boy Who Cried Werewolf". Pay attention to the clues, and you can solve the puzzle before the Gang. As always, Rozum isn't afraid to evolve the characters beyond formula. That's why Shaggy and Scooby in this particular tale come off as being very brave.
Robert Pope, Scott McRae and Heroic age are brilliant assets to Rozum's tale. The werewolf looks damn good, and that's not an easy thing to do, especially in a kid’s book. Gaunt, fur covered, gray with slavering snout and sharp-looking teeth, this s.o.b. looks like it could scare the snot out of someone. That gives Shaggy's fear even more substance.
The werewolf isn't the only character who benefits from the art team's care. Pope and company enhance the characterization through a thoughtful exploration in body language. Velma looks intently at clues. Shaggy quivers as the werewolf stalks closer. Scooby exhibits a determined, courageous look on his face. Daphne perches her chin on her arms folded to the top of the chair as she grills a suspect.
