Nika Boronina: What colour underwear am I wearing?
Agent 47: You're not wearing any underwear.
Agent 47: Nika.
Nika Boronina: Yes?
Agent 47: Stop talking or I'll put you back in the trunk.
Agent 47: The man you've been chasing is a killer. A Ghost. Rumor has it that he works for a group known only as "The Organization." So secret, no-one knows it exists. Takes no sides - yet it has ties to every government. Its sole purpose is the training and conditioning of professional killers. These men are selected at birth - rejects, orphans - all of them - unwanted and disposable. They are made experts in every aspect of combat. And programmed for one purpose... To Kill.
Nika Boronina: So are you going to kill me?
Agent 47: No.
Nika Boronina: You don't want to fck me and you don't want to kill me. I've never felt so much indifference in my entire life.
Jenkins: You don't have jurisdiction here.
Smith Jamison: We aren't here, which means when we open up on you and shred your bodies with automatic fire then this will never have happened.
Nika Boronina: What are you going to do?
Agent 47: What I do.
