The only part that annoyed me was Gendry's treatment during the whole thing. They had him team up with this group just to be their punching bag. Im happy that they made it so he wouldnt be killed, but come on!

1. First it wasnt a surprise the Brotherhood were remorseless. They are a cult and one of them has been killed so many times, I doubt he can recall the moral significance, plus they always use the Lord Of Light as an excuse, but WTF was Sandor doing butting in. He doesnt even like them enough to warrant defending them and he should not be talking at all considering he was left for dead by Sansa and Tortured by his own brother. I get that he's an ass by nature but you think he would have kept quiet.
2. Then he ultimately loses his weapon cause he gave it to Tormund, who ultimately threw it away to use the daggers he had THE ENTIRE TIME. If they didn't want him in the episode they couldve handled it in a better way. They could have had Jon send him to Dragonstone to either help forge Dragonstone weapons or send him to Winterfell or Dragonstone to learn more about combat or something. People have waited for eons for his return so what was the point in making him a doormat the moment he showed up.

As for the Arya/Sansa plot, I can side more with Arya in general. I dont agree with how she acted during this episode, but I can understand her motives. She thinks Sansa is turning into another traitor to her family (like Theon) all for the sake of her own gain (like Cersei). Sans hasn't really done much to prove otherwise and it didnt help that she just ignorantly dismissed what Arya's been through the same way Arya dismissed hers. Sansa was trying to undermine Jon and complain about his ruling way before arya showed up, idolizing Cersei's way of thinking and she clearly believes she is a better fit for ruling, which may become a problem when Dany shows up. While she has a right to feel angry with her sister for, apparently, no reason, Sansa could have worded her blowup at Arya more carefully, along the lines of:

"You think I lived in lavishment this whole time. You think I was pampered. You think I enjoyed watching FATHER BE KILLED! I couldn't control what Joffrey did, you damn well know that. And my "lavishment" was being abused and tormented by that brat only to be passed to the monster that ruled this castle. (Tearfully) I still remember when he threw me onto the bed and......(beat) You have no idea what Ive been through, all while thinking my family was gone forever. How could you think I would betray them!!? (Storms Off)"

I wish these two had talked about their experiences when they had the chance and I hope they use their acquired knowledge to figure out that Littlefinger is playing them both.

But this is all my opinion, if you agree or disagree, please reply
