so, bloodraven, summons bran, because he is "the one" who can stop the Others. but during bran's apprenticeship, bran goes all stupid and Night's King marks him and now Night's King can enter the weirwood network HQ. Bloodraven has to hurry and get bran ready, so his last lesson is to show bran what he needs to do to buy him some time to escape. bloodraven knew that bran was going to do stupid shit with the NK? then Bran wargs Hodor in the future and it causes Hodor of the past to have a vision of his death in the future, it blows his mind and he goes from Willis/walder to from then on be known as Hodor? did Hodor know this moment was coming? Hodor 'eyes went back to normal, right? so how is maura going to escape into the cold with 20,000 running WWs and Others on her heels and she doesnt know wtf she is going?
and Lithose, what is the Great Other? is that the first guy getting transformed by the CotF? is it an Ice Dragon? it isnt the NK is it? fuck that episode blew my mind, maybe the best GoT episode in regards to moving the story along.
