Peter A: What's going on?
Naya: Lock the doors.

Lambert 2: Can we still trust her?
Lambert 1: I suppose we'll find out.

You don't like me and I don't like you, but we have a common problem named Claude Lambert, so why don't we figure out what we're gonna fuckin' do about that?

Howard P

There's been an attack on their side. I think my other is at the center of it.

Emily P

Howard A: Look, I don't know I'm better or worse, but I know I'm not him.
Yanek: That is because you have never had to be.

Yanek: The thing of it is mankind has existed in a state of tension since the beginning of time. Between what is and what could be. There's a truth, too, that we can't deny.
Howard A: What truth?
Yanek: That any man may see himself as ordinary, but confront him with another version of his life and the one destroys the other. It's inevitable.
Howard A: I don't believe that.
Yanek: Your other is out there right now erasing you from your own existence.
Howard A: You don't know that.
Yanek: If it's occurred to you, it's occurred to him, and it has occurred to you, hasn't it? You are a gentle man, and this is war.

Howard A: We both married Emily.
Yanek: And now your other is living with her in your life.

Baldwin: You can't protect two sides forever.
Howard P: Let me worry about that.

Howard P: Why don't I just take you out right now?
Baldwin: You friends know about you. It's suspicious if you don't help them.

Howard A: Why are you in here?
Peter Quayle P: I'm serving my world in the fight against yours. Yanek says I'm one of the most important people here. I suppose now we know why.
Howard A: Yanek?
Peter P: Yeah. I give him secrets, my secrets, things about my life, things I'm afraid of, things that only I can know. So now Management knows my other's secrets.

Emily P: Aldus! It's not you we want, OK? I can protect you. We can help each other! [puts down her weapon]
Aldus: [drops his gun] Of course it was you. [jumps off the roof]

Emily P: Howard, the people who run that school are still out there. If you won't confront the truth about your wife, we can't stop them.
Howard A: The truth? What good did the truth do him when he found out? When he found out about you, he lost everything -- his wife, his daughter, everything. You were the one who said maybe love seeing someone for who they'd rather be.
Emily P: I wonder if you have the courage to see her at all.
Howard A: Don't come back here.

Counterpart Season 2 Quotes

Management: Why do you suppose you're so good at catching spies?
Naya: Because I know what it's like to be an outsider, to have my nose pressed up against the glass. I see the world the way they see the world.

Management: Do you believe in God?
Naya: Yes.
Management: Why?
Naya: Are you asking why I believe in God? Because I'm fairly certain I don't have to answer that.
