What a good episode. I'm digging this season. So much is going on! It's all finally moving toward the end!
I can't say that I have disliked any particular season of the series, but the plots in King's Landing and Dorne are pretty boring IMO.
As for this episode, I can get that Sansa is really, really pissed about Little Finger leaving her with Ramsay and her comments that she could what Ramsay has done to her even while she was standing there was pretty uncomfortable. But....he brought the Knights of the Vale with him and knowing she intends to take Winterfell back, they would have been a tremendous help. Stupid move on her part there IMO.
The Walkers attack was pretty cool. Damn those f*ckers show up fast! Rumors from the books are that the king of the White Walkers was a Stark. Wouldn't that be interesting?
