After me getting my distrust of Sansa off my chest, I forgot to mention my excitement with the rest of the episode:
Dany is going batshit crazy and I think whilst she will be winning for a while, she'll ultimately be her own downfall if she doesn't get her morals back in check.
She's also definitely not going to like it when it comes out that Jon has more claim to the throne than her now we know he's actually legitimate (OMG!)
Gendry is finally back!!!!
If he dies on the other side of the wall I will be so pissed because I don't think they're all coming back from this expedition, at least one of them will die, and most likely it will be a beloved character as we've not lost many of them yet (which isn't like GOT to be so kind to us viewers).
The dragon accepted Jon and allowed him to pet him, this shows that the dragon knows his loyalty also belongs to Jon, and I don't think Dany likes it too much, but was also in awe and impressed with the entire interaction at the same time.
Samwell best had of taken that clearly very important book along with him, as this is the proof needed for Jon to claim his place and true identity, especially as many are still unbelieving of Bran's visions.
I do wish Arya hadn't said all her thoughts to Sansa about her behaviour, because now she will have her hackles up and it's even easier for Little Finger to manipulate Sansa, which I think he is definitely planning to do with that scroll. I thinking catching Arya and knowing what she's up to was just an added bonus for him.
Oh my god, there's just so much that went on this episode that I could go on for ages about each scene
