The guests were subjected to odd tests by Tom, with one of them involving placing a silver bullet in their mouths (since silver is deadly to werewolves). Even Caroline participates in the test; being the last to receive her bullet. At that moment, however, Caroline turned heel when she suddenly transformed into a werewolf, with her villainous transformation beginning with her right hand covered with hair and her nails becoming long, black claws, much to the horror and shock of the rest of the group. After her transformation, the evil Caroline attacked Tom, who shot the villainess to death. After the event, it was revealed that Caroline contracted the werewolf disease from her dog, who was killed by the actual werewolf.
