Game of Thrones, Season 7

Jaime Lannister:
Thank you for coming. The other lords of the Reach look to you for guidance now more than ever; they might not have come if you hadn't.

Randyll Tarly:
If my queen summons me, I answer the call. And I've heard what she does to those who defy her.

Jaime Lannister:
You ride for Horn Hill today?

Randyll Tarly:
I have an army to mobilize. Won't be long before the fighting starts.

Jaime Lannister:
And which side will you be fighting for? You were the only man to defeat Robert Baratheon in battle. Not even Rhaegar Targaryen could...

Randyll Tarly:
It is a long ride back to the Reach, Ser Jaime. How may I serve?

Jaime Lannister:
I want you to be my ranking general in the wars to come. I want you to swear allegiance to Cersei, and I want you to help me destroy her enemies. All her enemies.

Randyll Tarly:
Including Olenna Tyrell? I'm a Tarly. That name means something. We're not oathbreakers, we're not schemers. We don't stab our rivals in the back or cut their throats at weddings. I swore an oath to House Tyrell.

Jaime Lannister:
You swore an oath to the Crown as well, Lord Tarly.

Randyll Tarly:
I've known Olenna since I was a child.

Jaime Lannister:
She was a great woman once. Now, she's broken. She wants revenge so badly, she brought the Dothraki to our shores. The Dothraki. In Westeros, for the first time in history. I know you don't like my sister, but you have to make a choice. Do you fight with us, or with the foreign savages and eunuchs? When the war is won, the Queen will need a new Warden of the South. I can think of no better man than Randyll Tarly.
