Bran and Hodor and them are still at the far north in the tree. I don’t think much is going to play out with them while further story lines develop.
The books sort of left them there at that location too with no further insight on them.
One of the elements that is missing in the tv series from the books is Arya’s ability to see through the eyes of Nymeria, her long lost wolf.
I think the last time we saw that was when her wolf killed the people pursuing her after she escaped from that castle, Harrenhal.
But it is worth noting that she, John and Bran all have the ability to see through the eyes of animals if not directly control them, which I think is eventually going to play a great role considering other “animals” around the lands.
The reason that Arya is my favorite character is because of her travels with the Hound and then her adventures in Bravos. I really cannot wait to see what becomes of her.
Interestingly, in the books Jaqen Hghar was never revealed to be the man at the temple. He was only shown as the elderly man throughout that entire scenario, though I suspected all along that it was indeed him.
So any Jaqen Dhagar gawking is bonus gawking provided by the tv series itself, they did officially spoil the books with that detail!
Yet I am sorely aggrieved that she left her faithful dog behind.
Surely, that make sense, does it not?
