Burnham: I wanted to show you a place of morality, of hope.
Emperor Georgiou: Let me tell you, daughter-who-is-not-my-daughter, in truth, you wished to save me because you couldn't save her. This regret that you have for what you did. It weakens you.
Burnham: Well, I feel it every day of my life.

Cornwell: How does this war end?
L'Rell: It doesn't. Klingons have tasted your blood. Conquer us, or we will never relent.

This is war. Not a child's game with rules.

Tyler: I'm okay.
Tilly: How can that possibly be true?

Stamets: You killed a good man. A man that I loved. Do you remember that?
Tyler: I do now.
Stamets: And does it gut you? Does it sicken you? Good. Maybe you're still human after all.

Sarek: What do you know of your counterpart, Captain Philippa Georgiou?
Emperor Georgiou: I know that she is dead and I am not. But I will leave you to determine which of us has proved stronger.

We are fodder for their feudal savagery. Our deaths, their spoils.

Sarek

Cornwell: I couldn't have imagined...
Sarek: That Lorca was an imposter from an alternate universe was not the most... obvious conclusion.

I could offer excuses. I was trying to destabilize the Terran Empire. I thought Starfleet could benefit from learning about an alternate universe. The truth is that I just couldn't watch her die again, Saru. I wanted to offer her more.

Burnham

Yesterday, you dined on the entrails of his brethren and today, you seek his favor?

Emperor

I was just thinking about everyone who has ever said that victory felt empty when it was attained. What a bunch of idiots they were.
