Take two of this terribly uneducated and ill-informed recap of Game of Thrones, here we go:
An old guy lurks in the middle of the woods and a boy is on the ground dead. In what looks to be a flashback the two of them are watching these two little boys sword fight when suddenly a girl rides in on a huge white horse. The first boy, who I’m pretty sure isn’t dead but is dreaming, is watching creepily over these children playing, and reveals that the boys and girl playing are his father, uncle and aunt, respectively. I guess he’s dreaming? I’m really not sure. Maybe it’s magic? I have no idea. When the old guy says it’s time to go, he immediately brings the boy back to what might be the chamber of secrets. At least it looks like that to me.
