“It’s not her” makes perfect sense. She’s communing with the Direwolf, and she realizes the Wolf in front of her is different now - and the Wolf is seeing the same thing. The Direwolves were almost mystically bonded to the Stark children. They were protectors. Arya isn’t the little girl who needs protection any longer, and the bond between them is broken. And Arya sees that Nymeria is no longer her childhood companion, but a grown direwolf with its own pack to protect now. They’ve basically grown apart, and they both knew it.
That’s a little bit trite if that’s what they were shooting for. A little too much like something you’d see in a Disney fairy tale.
I also didn’t buy Theon’s sudden return to Reekdom. He was just fighting bravely and well in a giant deadly melee. Having him bail like that just destroyed whatever twisted character arc he was going through. It just didn’t seem like the right thing for the character at that moment. It would have been far more satisfying to see him attack his uncle and immediately get swatted down and killed, just because it would have been more true to the character at that point.
The writing does seem to have taken a turn for the worse, and slightly more towards melodrama instead of drama. All of the plot lines were overwritten. The Sand Snakes were still just as annoyingly over the top, and good riddance to them. Jon’s reaction to Littlefinger was out of character, especially since he knew Littlefinger was responsible for all of them being alive and unflayed. He owes him a lot, even if he is a scheming rat. And he for sure needs the Knights of the Vale. So it was stupid.
There were some good moments, though. I liked the verbal tug of war between Varys and Daeneris. They both legitimately came off as formidable verbal sparring partners. It was a fun scene. And I do like that both Tyrion and Jon Snow were supporting each other so strongly. It made their earlier meeting scenes even better.
I even liked the Lannister scenes. I thought Cersei did the best with the cards she had, and the people she was trying to convince were rightfully skeptical.
I wonder if the rise of Lord Tarley is going to result as some point with he and his son meeting on opposite sides of a war.
