Viggo Tarasov: I heard you struck my son.
Aureilo: Yes, sir, I did.
Viggo Tarasov: And may I ask why?
Aureilo: Yeah, well, because he stole John Wick's car, sir, and, uh, killed his dog.
Viggo Tarasov: Oh.
John Wick: People keep asking if I'm back and I haven't really had an answer, but yeah, I'm thinking I'm back.
Viggo Tarasov: John wasn't exactly the boogeyman. He's the one you sent to kill the fucking boogeyman.
John Wick: You can either hand over your son, or you can die screaming next to him.
Viggo Tarasov: In a bar, I once saw him kill three men... With a pencil.
Viggo Tarasov: I'll say this for you, John... They sure as fuck broke the mould with you.
Viggo Tarasov: What happened, John?.. We're professionals... Civilized.
John Wick: Do I look civilized to you?
Answer: No. Regardless of any cancellation that Viggo made after-the-fact, the "Cardinal Rule" still applies to Marcus. He accepted the contract, he was contractually-obligated to kill John Wick, and he failed to kill John Wick. Marcus broke his word, essentially, which was an inexcusable violation.
