• This episode introduces the Jem'Hadar and the Vorta. The Jem'Hadar are the Dominion's genetically engineered warriors. The Vorta's homeworld is Kurill Prime.
  
• This is the only episode where a Vorta uses psychokenisis. Eris also doesn't recognize Odo as one of the Founders.
  
• The U.S.S. Odyssey NCC-71832 is the third Galaxy-class starship we've seen (the others are the U.S.S. Enterprise NCC-1701-D and the U.S.S. Yamato NCC-71801). The Jem'Hadar destroy the Odyssey. Starfleet should have sent the Enterprise :)
  
• The Bajoran outpost in the Gamma Quadrant called "New Bajor" was destroyed by the Jem'Hadar.
  
• This episode was nominated for an Emmy for "Outstanding Individual Achievement in Special Visual Effects" (It lost to Voyager's pilot episode, "Caretaker".)
