Odo is lured to a secret meeting site, where he finds himself face to face with Weyoun, the Vorta leader of the enemy Dominion. Weyoun announces that he's decided to defect and, in exchange for asylum, he promises to provide valuable information that could help the Federation win the war. After the two board Odo's runabout, the ship is hailed by the Cardassians. Odo is shocked when the monitor displays Weyoun standing beside Damar.

• Weyoun 5 was killed in a mysterious transporter accident, and was replaced by Weyoun 6, but he was found to be "defective" and was quickly replaced by Weyoun 7. That means that the first Weyoun we met in season 4's "To the Death" was at least Weyoun 4.
  
• The Dominion has a new Ketricel White facility in the Pelosa System in Sector 507.
  
• Gul Russol was Odo's Cardassian informant, who was executed when the Dominion and Cardassians formed an alliance. He may have been the Cardassian informant featured in the episode "Improbable Cause".
  
• A disease has spread through-out the great link and the Founders are dying. Weyoun 6, knowing that Odo will be the only changeling to survive, only wants to serve him in the "New Order."
  
• The Vorta used to be ape-like forest dwellers who lived in hollowed-out trees. A Vorta family saved a wounded changeling and the changeling promised to one day transform the Vorta into a species who would have a part in a great new empire. The Vorta have very little sense of taste, but enjoy Kavanuts and Rippleberries. They have been genetically engineered to worship their Gods, the Founders. All Vorta have a termination implant in their brain.
  
• Chief O'Brien gives Nog his access code, who then arranges a series of trades for a graviton stabilizer for the Defiant.
  
• Chief Edgar Willoughby is the quartermaster of the sector's supply facility.
  
• Rule of Acquisition #168: "Whisper your way to success."
  
• The Ferengi believe in The Great Material Continuum, which holds the universe together.
