By the way, the Stannis fans (like myself) are rightfully peeved about what they did this episode. In the book, Stannis burns his wife's relative because he committed treason by going behind his back to try and make peace with the Lannisters (So when Melisandre wants to burn people in a sacrifice he's like "fine, take this guy who's going to die anyway"). But in the episode he kinda just indifferently watches while his wife and Melisandre burn the relative for simply not believing in the Lord of Light.
Ah ok but...
