Game of Thrones, Season 5

Melisandre:
Lord Commander.

Jon Snow:
How can I help you?

Melisandre:
Come with us when we ride south. None of us know the castle as well as you do. Its hidden tunnels, its weaknesses, its people. Winterfell was your home once. Don't you want to chase the rats out of it?

Jon Snow:
Castle Black is my home now. The Night's Watch take no part in the wars of the Seven Kingdoms.

Melisandre:
There's only one war. Life against death. Come. Let me show you what you're fighting for.

Jon Snow:
You're gonna show me some visions in the fire. Forgive me my lady, I don't trust in visions.

Melisandre:
No visions. No magic. Just life. [she pulls his hand under her robe] Do you feel my heart beating? There's power in you, you resist it and that's your mistake. Embrace it. The Lord of Light made us male and female. Two parts of a greater whole. You're not joining this power. Power to make life, power to make light, and power to cast shadows.

Jon Snow:
I don't think Stannis would like that very much.

Melisandre:
Then we shouldn't tell him.

Jon Snow:
I can't.

Melisandre:
Why?

Jon Snow:
I swore a vow. I loved another.

Melisandre:
The dead don't need lovers. Only the living.

Jon Snow:
I know. But I still love her.

Melisandre:
[Goes to the door before she turns back to Jon] "You know nothing, Jon Snow."
