When Melisandre turned up at the 11th hour in the Battle of Winterfell, this Game of Thrones fan internally groaned.

When has Melisandre done literally anything of use? When? Name me one time, and I’ll show you when she messed up royally. She’s the Professor Trelawney of the Game of Thrones franchise, only instead of being batty and harmless up in a Hogwarts Divination tower, Melisandre insists on continuing to stick her finger into as many pies as she can, just for the fun of it.

And yet I have to admit, Melisandre was actually pretty important last week. She helped on a granular level by being the only person to provide us, the poor viewers, with some lighting so that we could see what was happening. She lit those Dothraki swords and she lit the Winterfell trenches. And, at a very crucial moment, she lit a fire in Arya’s belly by reminding her of the prophecy she foretold for her future.
