Henry Cavill: August Walker
August Walker : How many times has Hunt's government betrayed him, disavowed him, cast him aside? How long before a man like that has had enough?
August Walker : [to Lane] Why do you have to make things so fucking complicated?
August Walker : [to Ethan, while hanging off the wreckage of a helicopter] Why won't you just die?
Luther Stickell : [to Hunt about Walker] He's not just some observer. He's an assassin.
Ethan Hunt : [to his team] Don't trust anybody outside of this room.
Alan Hunley : You go rogue, he's been authorized to hunt you down and kill you.
August Walker : That's the job.
[sends in his troops]
August Walker : No hard feelings.
August Walker : Hunt's the only friend you've got. You're only alive today because he didn't have the guts to kill you. Sloane was right. The IMF is Halloween. Nothing but grown men wearing...
Solomon Lane : [Smiling nervously] What?
Solomon Lane : [Walker removes Lane's mask to reveal Benji] It's just the job. No hard feelings.
Solomon Lane : [quoting from John Lark's manifesto] "There cannot be peace without first a great suffering. The greater the suffering, the greater the peace."
August Walker : When I wrote those words, I wasn't referring to your peace or Hunt's suffering. The old world order needs dismantling, and we have the tools to dismantle it. All you seem to care about is that Hunt lives to take the blame. That's not anarchy. That's revenge.
August Walker : Is it true Lane gassed a village of 2000 people?
Ethan Hunt : Yes.
August Walker : Is it true he brought down an entire passenger plane just to kill one man?
Ethan Hunt : Yes.
August Walker : Is it true that he...
Ethan Hunt : Look, Walker, whatever you've heard, if it makes your skin crawl, it's probably true.
August Walker : Holy shit. You're the guy that caught him, aren't you? How long do you think he's gonna keep that to himself?
Ethan Hunt : [Ethan confronts Walker in the elevator after Walker is revealed to be John Lark, and Walker holds Ethan at gunpoint] You can't do it, can you? Not until you get your plutonium.
August Walker : No, he still has plans for you. You're gonna turn yourself in and admit you're John Lark, then watch the old world implode from your dark little cell.
Ethan Hunt : And if I don't?
August Walker : [Walker takes out a picture of Julia with her new husband Erik, Ethan gasps in horror upon seeing the picture] I'm her guardian angel, Hunt. If I see you again, she dies. If you try to warn her, she dies. Know when you're beat.
Alan Hunley : I believe I've been given a choice to protect you or the IMF, which is why I'm bringing you in.
Ethan Hunt : And if I refuse?
Alan Hunley : [referring to Walker] What do you think he's here for? You think he's some observer? He's an assassin! Erika Sloane's number one plumber. You go rogue, he's authorized to hunt you down and kill you.
August Walker : It's the job. No hard feelings.
Alan Hunley : Accept it, Ethan. You've lost this one. What's done is done.
Ethan Hunt : No, sir. No.
Alan Hunley : I am not asking you, I am giving you a direct order. This mission is terminated. Now!
August Walker : There cannot be peace without first a great suffering. The greater the suffering, the greater the peace.
