The Secret Serum
A vampire is loose in Crystal Cove stealing what appears to be random items. Things have become strained within Mystery Incorporated, and this time, the gang is truly torn in half. Velma refuses to speak to Shaggy, and Fred and Daphne begin to grow apart. The girls decide to investigate separately from the boys. Daphne and Velma begin to suspect that the vampire may be Daphne’s mother. After receiving help from a mysterious man, Daphne figures out the connection between the stolen items. The gang ultimately unites to capture the vampire, but Velma declares that “maybe we’re not a team anymore”. The episode ends with the gang returning to their homes separated. Daphne’s helper is revealed to be Mr. E’s mysterious subordinate from “The Legend of Alice May”, who observes the gang through binoculars from afar.
