I wonder if the Other, the evil god beyond the wall that the red priests fear, has some connection with the actual Others? Maybe their leader of some sort. Given that R'hollor is a fire god, bringing in the Other (or followers of the Other) as some sort of literal representation of ice would bring some nice balance to "A Song of Ice and Fire."
While on the topic of the Others, I wonder if we ever could/would get a POV from one of the beings beyond the wall? An Other, or maybe a Child of the Forest. Also, I wonder if maybe the Others aren't truly evil like they have been portrayed. They have to have some sort of agenda of their own that we just don't know about yet.
Completely unrelated to the above speculation, but I'm definitely under the impression that Ser Robert Strong is Gregor Clegane (maybe I just don't want to see those vile Clegane brothers die
). Will be very interesting to see what lies beneath that helmet, when he finally takes it off.
Since the horn that Mance had and Melisandre burned was revealed by Tormund not to be the actual Horn of Joramun, I wonder if that horn that Jon discovered (in
A Clash of Kings, if I remember correctly) alongside the Night's Watch clothes and dragonglass will be it. He gave it to Sam if I'm remembering right.
And speaking of horns, will be very interesting when Victarion and Daenerys clash. I'm sure Dany is going to somehow end up with Dragonbinder.
And now, on the topic of Dragonbinder, which comes from Valyria, I hope we get to see the ruins of Valyria before this is all over. And Asshai. Both would be cool.
