- Lexa: I lost someone special to me, too. Her name was Costia. She was captured by the Ice Nation, whose queen believed she knew my secrets. Because she was mine... they tortured her, killed her, cut off her head.
- Clarke Griffin: I'm sorry.
- Lexa: I thought I'd never get over the pain, but I did.
- Clarke Griffin: How?
- Lexa: By recognizing it for what it is... weakness.
- Clarke Griffin: What is? Love? So you just stopped caring about everyone? I could never do that.
- Lexa: Then you put the people you care about in danger, and the pain will never go away. The dead are gone, Clarke. The living are hungry.
- Marcus Kane: Clarke is right. We need to do this. Peace with the Grounders is the only way we'll survive.
- Dr. Abigail Griffin: Oh, I don't think they know what peace is.
- Marcus Kane: The commander does.
- Dr. Abigail Griffin: She's a child. They're being led by a child!
- Marcus Kane: So are we.

- Lexa: Some on my side say that's not enough. They wanted the murderer to suffer as our tradition demands. But they do not know that your suffering will be worse. What you did tonight will haunt you until the end of your days.
- Lexa: Tell me something, Clarke. When you plunged the knife into the heart of the boy you loved, did you not wish that it was mine?

- Monty Green: [wakes up in a cage] Harper. Hey, Harper! What did they do to you?
- Harper: [in an adjoining cage] 47. They built one for each of us.

- Bellamy Blake: What we need is an inside man. Someone to be our eyes and ears.
- Clarke Griffin: Forget it. It's too dangerous.
- Bellamy Blake: Clarke, if you can make it out, I can make it in.
- Clarke Griffin: I said no.
- Bellamy Blake: Since I don't take orders from you... I'm gonna need a better reason.
- Clarke Griffin: I can't lose you, too. Okay?
- Dr. Abigail Griffin: You don't want justice. You want vengeance.
- Indra: You have not seen my vengeance.
