Beric Dondarrion: I'm not fighting so some man or woman I barely know can sit on a throne made of swords.

Jon Snow: So, what are you fighting for?

Beric Dondarrion: Life. Death is the enemy. The first enemy and the last.

Jon Snow: But we all die.

Beric Dondarrion: The enemy always wins. And we still need to fight him. That's all I know.
