- Nikita Dragovich: [to Mason] You should've been my finest agent. It would have all been so much simpler.
- [aims pistol at Mason, then Hudson shoots Dragovich in the shoulder]
- Special Agent Jason Hudson: Dragovich!
- [they exchange fire]
- Alex Mason: [pulls Dragovich into the water] It is simple! I'm gonna kill you! You tried to fuck with my mind! You failed!
- Nikita Dragovich: You don't know anything!
- Alex Mason: [punches him repeatedly] You tried to turn me against my own! You tried to make me kill my own president!
- Nikita Dragovich: [smirks] Tried?
- [Mason proceeds to strangle and drown him]
- Alex Mason: I know where the numbers station is. It's a ship... I saw it a long time ago. The Resulka.
- Special Agent Jason Hudson: Where?
- Alex Mason: Cuba.
- [guitar riff plays as Hudson puts on his sunglasses and the mission ends]
- Alex Mason: [Mason just hopped on a train from a truck, while Reznov is still in the truck as the two are escaping the Vorkuta labor camp] Step eight, Reznov: Freedom!
- Viktor Reznov: For you, Mason! Not for me!
- Viktor Reznov: [as he prepares to shoot Steiner] My name is Viktor Reznov, and I will have my revenge!
- Viktor Reznov: [after Mason destroys the underwater base] You did it, Mason. You did what I could not.
- Alex Mason: Friedrich Steiner. This is the end.
- Friedrich Steiner: You... I know you... Vorkuta! You don't know... what we did to you!
- Special Agent Jason Hudson: [on comms] Mason, talk to me.
- Viktor Reznov: Your evil has claimed the lives of many good men. No longer.
- Friedrich Steiner: Killing me will not stop Nova.
- Viktor Reznov: I do not care about Nova! My name is Viktor Reznov...
- Friedrich Steiner: No!
- Viktor Reznov: And I will have my revenge!
- [shoots Steiner in the head]
- Viktor Reznov: [speaking to Mason in Vorkuta prison] My father was a musician in Stalingrad. During the German occupation, the sound of his violin filled the air with magnificent music - Korsakov, Stasov - many of great nationalist composers. To my countrymen, it was a symbol of hope. To the Germans, it was a symbol of defiance. Even now, his music still haunts me. The Nazis slit his throat while he slept. Collaborating with a Nazi is a betrayal, a betrayal against of all Mother Russia. Dragovich and Kravchenko were not troubled by such matters. They looked only to advance towards their own interests and agendas...

- Alex Mason: I made the mistake of not confirming the kill five years ago at Baikonur.
- Special Agent Jason Hudson: You sure you're still not brainwashed?
- Alex Mason: Would it matter? The son of a bitch needs to go down once and for all!
- Fidel Castro: [indicating Nixon] And why is he here? He lost!
- John F. Kennedy: As I always say, forgive your enemies, but remember their names.
- Special Agent Jason Hudson: [voice disguised as interrogator] We wanted Steiner alive! Why did you have to kill him?
- Alex Mason: 'Cause the numbers were telling me to! Why don't you fucking understand?
- Lev Kratvchenko: [Mason breaks in to kill Kratvchenko who hits Mason with a chair and starts beating him] Not this time, American.
- [Woods fights with Kratvchenko who knocks Woods down; Mason goes for his pistol and gets stopped]
- Lev Kratvchenko: You again. I should have killed you in Vorkuta.
- [Woods recovers and stabs Kratvchenko]
- Frank Woods: Got you now, you son of a bitch.
- Lev Kratvchenko: You... will die with me.
- [pulls his grenade pins, grabs Woods and they both crash out of the window; the grenades blow]
- Alex Mason: Woods!
- Frank Woods: [as a silhouette] I got you, Mason.
- Alex Mason: Woods?
- Frank Woods: You're okay.
- [first lines]
- Special Agent Jason Hudson: [voice disguised as interrogator] Wake up. WAKE UP.
- Alex Mason: [dazed and confused] Where am I? Where's Reznov?
