    • Odo: Where's the Changeling? I lost him in the conduits. O'Brien: We haven't seen him. (another Odo emerges from another access port) Changeling/Odo: Wait. It's me, Odo. O'Brien: (looks at both Odo's) You don't say. Changeling/Odo: Chief, remember the last time we went kayaking in the holosuites? You had lamb stew for lunch. O'Brien: That's right. Odo: (to O'Brien) But you forgot to bring a fork. Anyone could have gotten that information. Computer: Auto destruct in five minutes. Changeling/Odo: You'd better make a decision. We're running out of time. O'Brien: Look, I've more important things to do than play 'Choose The Changeling'. (to co-worker) Keep the phaser on both of them.

    • Changeling: Why are you protecting these solids? You don't belong with them. You belong with us. Let go. Don't you see? You've lost. It's too late for you to help them, but it's not too late to help yourself. Link with me, Odo. We can escape together. Odo: I don't think so!

    • Odo: Captain, there's something you need to know. The changeling, before he... died, he whispered something to me. Sisko: Go on. Odo: He said... 'You're too late. We're everywhere'.

    Trivia (9)

    • This episode marks Benjamin Sisko's promotion to Captain. Dax is promoted to Lieutenant Commander and Bashir is promoted to Lieutenant.

    • First appearance of the Defiant's engineering room.

    • This is the only episode where blood tests are an effective way of screening for changelings. The Founders quickly find a way around this. In the very next episode, the Changeling posing as Martok fakes this test in front of Sisko and Kira, then acts paranoid that they might be changelings, thus completing his disguise.

    • This episode marks the second time out of three that we have seen a Changeling die. The first time was in the episode "Crossover" and the last time was "Apocalypse Rising".

    • It is shown that Bolians have blue blood.

    Allusions (2)

    • The Thing
      The blood test to detect changelings is identical in concept to the ones given in John Carpenter's remake of The Thing (1982).

    • Alien
      The search for the changeling through the Jefferies Tubes and firing phaser blasts down them is very reminiscent of the use of flamethrowers in the air ducts in Alien (1979).
