I thought it was an excellent episode for this stage in the series; it wasn’t a knock out OMG episode all the way through like we’ve with some others, but it’s setting everything up nicely to go forward. It did have quite the badass ending with Dany taking the khals out – I’m glad she did it herself (with presumably a little help from Jorah and Dario) rather than Drogon sweeping in to save her again.
I had something in my eye when Jon and Sansa reunited, and Margaery and Loras for that matter. Genuinely emotional moments. Margaery is going to do whatever it takes to get them out of there and the 7 Gods will be of no use to the High Sparrow against the might of her and Lady Olenna 
I loved the bit where Jon read the letter and Sansa was the driving force behind going back to Winterfell. She’s one of my favourites as she has been taught how to play the game by the best and now she’s playing it. The girl has real steel beneath the silk. That letter is apparently in the books but it’s delivered to Jon before he dies and it’s what makes him want to leave The Wall, leading to the Brothers stabbing him. I liked that they brought it in to the show, albeit in a different way. Presumably Littlefinger’s army is going to join up with Jon’s, seeing as LF is on his way to Winterfell anyway.
I also loved Thormund’s O-O at Breinne; you could almost hear him thinking ‘What a woman!’. Interestingly Brienne confirms she killed Stannis here, but I still don’t believe it for some reason. I’m firmly in the camp of never believe they’re dead until you see the body and, seeing as we’ve seen the deaths of the other Baraetheon men (Renly, Robert, Joffrey), it’s really odd they’re not showing us Stannis. Davos is almost at the point where he’s found out about Shireen and I wonder what he’ll do. He’s a practical, cool customer, but will this be a step too far?
I'd already written Osha off as a dead woman walking tbh. Fair play to her for having a go at killing Ramsey, though, feisty to the end. You know you're watching GOT when you think 'Oh thank the gods she's just bleeding to death and not being flayed alive'!
