Davos Seaworth (about Shireen): Tell him what you did to her. Tell him!

Melisandre: We burned her at the stake.

Davos Seaworth: Why?

Melisandre: The army was trapped. The horses were dying. It was the only way.

Davos Seaworth: You burned a little girl alive!

Melisandre: I only do what my Lord commands.

Davos Seaworth: If he commands you to burn children, your Lord is evil.
