And when Jerry does a scan on the clue, he discovers something quite unusual- it belongs to a woman named Bertha Bombshell who was his girlfriend many, many years ago! What the spies eventually realize is that Bertha is an aging pageant queen bent on recapturing her former glory...the only problem is, ever since she broke into WOOHP, stole the serum, and administered it to herself, Bertha's now experiencing all sorts of side effects -side effects that make her determined to not only destroy the latest pageant she's entered, but the spies as well!
