I had tons of thoughts after watching this ep on Monday and even multiquoted lots of posts to respond to and then I got interrupted, life happened and suddenly there were over a dozen more pages when I checked in today. So, I'll just post some thoughts below instead.
For a moment, I thought Dany was pregnant during the celebrations. She wasn't drinking after the toasts, was watching Jon with his buddies and Sansa seemed to be side-eyeing. Turned out to (most likely) be false alarm though. It was just her watching Jon being praised/loved and probably thinking how the truth about his parentage would ruin her dream of the iron throne.
Sansa was out of line (and not really needed, anyway) during the war meeting or whatever it's called. It was not her place to state the soldiers needed rest when she was in a room with those soldiers' commanders and the queen. And then to be all "uh, I don't know, lemme ask" when Dany questioned her rubbed me the wrong way. You don't go into a meeting unprepared.
Also, Dany has been doing this (fighting wars/conquering) for quite some time now and I think she may just have a tad more insight into her men's fitness than Sansa. Not to mention that Dany's men are Dothraki and Unsullied, both pretty much born and bred to fight. They can handle a walk south, especially if half of it is traveling by sailboat. Jon was there to speak for the northerners and he clearly had no objection to leaving again. Might be best to get them all to keep moving/fighting before they settle back into their old routines and will refuse to go to war again a few months on.
Arya apparently did a 180 from family/sticking together and leaving Winterfell with no plans to return without saying so much as goodbye. Odd.
Did not see Rhaegal's death coming! It was so sudden, I almost wondered if it was some weird TV thing where Dany was having a nightmare about losing another dragon and then we'd see her wake up. Alas, it was not so 😞 The weirder part was indeed that neither Dany nor her dragons (who have a pretty good survival instinct) apparently noticed that entire fleet. I was also expecting Drogon at the least to dracarys all the ships, if not Dany giving the command. Would have even settled for a sad lil' dracarys from Rhaegal as he fell, like a last attempt to protect his mother and sibling.
The number of ballistas on the ships and later KL was ridiculous! They'd probably need a decade to make that many, assuming they had enough materials and manpower (or money to buy them) which they clearly didn't after the carnage left by the war of five kings.
I like the idea that Dany's little group at the parlay was small because a) she does not want Cersei to know her actual numbers and b) because they all had to fit on Drogon to fly them over.
When Tyrion mentioned Cersei's pregnancy and we kept going back and forth between him on the ground and Cersei and her people on the walls, I wasn't thinking Missandei should jump while dragging Cersei with her; I kept thinking Euron would realize Tyrion knowing about the pregnancy meant the baby couldn't be his (and was most likely Jaime's) and he'd unceremoniously shove her off the wall, to her death...
I was hoping Missandei's "dracarys" would get Drogon's attention and he'd attack unexpectedly and kill them all in revenge for Missandei's death.
I think that was it. More might come to me later.
I don't think it's all that strange for Dany not to "mingle" with her subjects. One, because they're her subjects, like when have you ever seen Cersei or Robert mingle with the peasants? Two, the northerners pretty much hate her, or at least they did when she first arrived which was only a couple of days ago. Third, she grew up as the little sister of the "beggar king", on the streets until they were taken in by Illyrio (and possibly before that in the house with the red door and lemon tree) and then she was married off to a "savage". She went from adolescent to young woman among the Dothraki, that's when she came into her own and how she learned to participate in society. It's pretty amazing she's turned out as well as she has.
