Game of Thrones, Season 3

[Melisandre is preparing to depart Dragonstone]

Stannis Baratheon:
You refuse to tell me where you're going?

Melisandre:
I don't know yet. The fires will show me.

Stannis Baratheon:
How long will you be gone?

Melisandre:
[exasperated] I don't know! [Stannis grabs her]

Stannis Baratheon:
You're abandoning me!

Melisandre:
I will never abandon you. You are the Son of Fire; I am sworn to serve you!

Stannis Baratheon:
Then serve me now.

Melisandre:
When I return you will understand.

Stannis Baratheon:
My enemies think they've destroyed me. They're laughing at me, the way Renly laughed at me. I want Joffrey dead. I want Robb Stark dead. Make me another 'son'.

Melisandre:
I cannot.

Stannis Baratheon:
Why?!

Melisandre:
You don't have the strength. It would kill you.

Stannis Baratheon:
I'm not so easily killed; men have been trying for years. I want you.

Melisandre:
Your fires burn low, my king. [Stannis turns to leave] There is another way, a better way.

Stannis Baratheon:
You told me your magic requires a king's blood.

Melisandre:
Yes.

Stannis Baratheon:
I am the one true king!

Melisandre:
You are. But there are others with your blood in their veins. You will sit on the Iron Throne, but first there must be sacrifices. The Lord of Light demands it.
