Game of Thrones isnt necessarily the most quotable of shows, but a few key lines have managed to transcend the show and take on a life of their own. The Stark words, Winter Is Coming is one great example, as is the Braavosi saying Valar Morghulis. One of the most popular is Ygrittes oft-repeated saying: You know nothing, Jon Snow. After the red-headed wildlings tragic death, it seemed that wed never get to hear those words on the show again. Then, in season 5, another red-head, a Red Priestess, brought them back to life, as Melisandre did what so many fans have done and quoted Ygritte. It seems as though its an attempt to make Jon feel bad, after he refuses her advances, although quite how the witch knows the famous words is another matter. Maybe its just pretty clear by the expression on his face that the boy knows nothing.
