Crimson Cloak's appearance prompted Batman and Mystery Inc. to reopen Batman's unsolved case about the disappearance of Dr. Leo Scarlett. They briefly considered Sam Scarlett as a potential suspect, but Batman explained that even though he swore revenge for his son's disappearance he was severely affected by the tragedy and was likely not capable of such an act. When Batman, Mystery Inc., and the Mystery Analysts of Gotham rescued Leo, Sam was brought to the scene of the incident and was overjoyed to be reunited with his son, thanking Batman.
