Accountant: A pact, huh? Funny—he's never mentioned you.
(looks at the Cultist's shattered legs)
Accountant: Whoa, those are fucked!
After the Accountant interrupts the police trying to apprehend Milton and Piper (thereby allowing them to escape), he whips out his coin, tosses it into the air, and it becomes a FBI badge which he shows to the police captain, and we get this exchange:
Captain: No goddamn way! Ain't no goddamn way in God's good heaven are you a FBI agent!
Accountant: Gentlemen, I need you boys to stand down. Captain, you know what this badge means, right? Federal Bureau of Get-the-Fuck-Out-of-My-Way! You boys just stumbled onto an ongoing investigation.
The Accountant then exposes one of the cops as a cultist working for King and tells him to call him. When the cop/cultist does, the Accountant leans in close to hear.
"If your definition of 'forever' is the next five seconds, then you'd probably be right."
The Accountant's reaction when Piper gets free from his grasp, grabs the Godkiller, and trains it on him.
