Game of Thrones, Season 7

[Jaime has returned to King's Landing and confronts Cersei]

Cersei Lannister:
How many men did we lose?

Jaime Lannister:
We haven't done a full accounting.

Cersei Lannister:
It's not only armies that win wars. We have the Tyrell gold, we have the Iron Bank behind us; we can buy mercenaries. Not the same as our men, but they'll fight if they're well-paid, which they will be.

Jaime Lannister:
I just saw the Dothraki fight. They'll beat any mercenary army. They'll beat any army I've ever seen. Killing our men wasn't war for them, it was sport! Her dragon burnt a thousand wagons! Qyburn's scorpion fired bolts bigger than you, they couldn't stop it and she has three of them! This isn't a war we can win.

Cersei Lannister:
So what do we do? Sue for peace? I sit on her father's throne, the father you betrayed and murdered! And in her mind, she's winning! What sort of offer do you think she'd make? Maybe we can count on Tyrion to intercede on our behalf? By way of apology for murdering our father and son...

Jaime Lannister:
He didn't.

Cersei Lannister:
You saw the crossbow, you saw his body.

Jaime Lannister:
I'm not talking about Father. Tyrion didn't kill Joffrey, he had nothing to do with it.

Cersei Lannister:
After all this time, it still amazes me that you...

Jaime Lannister:
It was Olenna. She confessed before she died.

Cersei Lannister:
And was this before or after she drank the poison you so kindly provided for her?!

Jaime Lannister:
After.

Cersei Lannister:
And you believed her?

Jaime Lannister:
If you were Olenna, would you rather have seen your granddaughter married to Joffrey or Tommen? Which one would Margaery have been better able to control? Which one would have made Olenna the true ruler of the Seven Kingdoms? She was telling the truth. [Cersei's smug expression twists into one of fury as she realises Jaime is right]

Cersei Lannister:
I shouldn't have listened to you. She should have died screaming.

Jaime Lannister:
She's dead, like her son, like her grandchildren, her whole House. And if we don't find a way out of this war, we'll follow them.

Cersei Lannister:
So we fight and die or we submit and die; I know my choice. A soldier should know his.
