Lena Headey, Emilia Clarke, Alfie Allen, and Iwan Rheon popped their heads into The Late Late Show with James Corden to show us what it would be like if the wall of heads from Game of Thrones tried to order a pizza. Another issue the characters were faced with was when Khaleesi (Clarke) told everyone, “I’m not really doing gluten this month.” Keep in mind that this is the Mother of Dragons, so it kinda makes sense that she would be on the Atkins Diet.
