In this episode we talk about the Vigenère cipher with Dan. Many things about the  Vigenère cipher - including it's name - have been misattributed - find out why. The story also resolves last week's mystery and follow the trail of clues. And Dan makes a new segment without host permission. Barnabas seems to think that he's loosing control of the show.
