Didn't someone posted a link a while back to a fan theory about Hodor that proved correct? I swear I have read already the "Hold the door" connection, but maybe it was in reference to the Tower of Joy flashback.
So... the Children of the Forest made the Others / the White Walkers? weren't they at war with each other?
Also, is it me or all the White Walkers are played by the same four dudes? I swear that a long haired one is the same that Jon killed in Hardhome.
Loved however the badass way they walked through fire, all looking like "yeah bitches think fire can stop us", haha!
And what a real life lesson from Varys. "I suppose it's hard for a fanatic to admit a mistake. Isn't that the whole point of being a fanatic? You're always right. Everything is the Lord's will."
Finally, about Littlefinger's endgame... I'm a bit puzzled about it myself. He probably wants to take the credit for bringing the decisive factor into the battle for the North - the large army of the Vale (so he has the Vale for himself, the gratitude of the North, and maybe he crushes the Freys since he's at it), but why did he give Sansa to Ramsay in the first place, since he seems to care for her in his own warped way? he needed to "park" her away to let Cersei know he's still on her side since he couldn't kept her hidden forever?
