• All of the Next Generation cast appear on screen together for the first time since Star Trek: Nemesis.
  
• Geordi lowers the positronic barrier between Data and Lore. Lore looks as if he's about to take over, while Data gives him items representing key memories. The memories he takes from Data allows Data to eliminate the Lore personality. The memories include a deck of poker cards, his Sherlock Holmes cap and pipe, his holographic memorial of Tasha Yar, and Spot.
  
• Raffi discovers what the changelings did with Picard's physical remains. They removed the parts of the brain infected with irumodic syndrome.
  
• Vadic kills Vulcan lieutenant T'Veen when Jack fails to come to the bridge in time.
  
• Vadic is killed when Data opens the bridge escape hatch doors and she is pulled into space. She freezes and shatters when she hits The Shrike.
  
• Worf wears the leather Starfleet field jacket for the first time in this episode (security gold), and he has a captain's rank of 4 pips.
