It's tough not to notice how flexible time is on Game of Thrones. Especially coming into the later seasons, everyone but Bran seems like they have an Enterprise teleporter ready to magically reassemble their molecules a thousand miles away. It can be frustrating and even bewildering, but it's a sacrifice made in an attempt to move along the plot as we head towards the finale.
That being said, the whole situation with the magically healing greyscale sure is a headscratcher. Remember, when we last saw Jorah, Sam was peeling the top layer of his skin like a burnt puss marshmallow. Exactly one episode later, his skin seems to have healed almost overnight.
I say overnight specifically because the operation was done out of desperation, since Jorah was slated to be shipped out the next day. You could imagine a scenario where the archmaester finds a post-op patient in a cell and decides to wait it out a month or two to see what comes of it -- but that's not what happens. When Sam's boss examines Jorah's scar tissue and then subsequently gives a nice but stern lecture to his Citadel intern, the conversation plays out like this is the first time either of them is addressing Jorah's new condition.
Did the random ointments and oils Sam applied to Jorah's skin really heal them that quickly? Does... does Sam know magic? Is it really as simple as reading a book and following the instructions? There aren't easy answers to those questions, but when the logical alternative would be watching Jorah fester in a leper cell for five more episodes, we kind of have to take what we can get.
So far this season, Game of Thrones has taken great pains to explain that Daenerys could stroll into King's Landing any time she wants. Everyone agrees that with an army of Dothraki, Unsullied, Greyjoys and Dorne on her side (not to mention dragons), taking King's Landing would be only slightly more than trivial. But Dany doesn't want to obliterate the people, she wants to save them and rule them. Kind of a stupid move in the grand scheme, but it's hers to make.
In the meantime though, how the hell is she supposed to feed an army that could theoretically take over Westeros? Remember, they landed on Dragonstone, an island with little in the way of resources. The whole place was empty when they arrived, and it seems doubtful that Stannis would have left any food behind since he probably didn't intend to retreat. Any stores that the fleet brought over would surely be running very low by now, especially considering it's likely been weeks since Dany arrived (at the very least -- how long does it take for Jon to sail from Winterfell to Dragonstone?). Even with a large part of the forces captured, killed or otherwise in disarray, that doesn't account for everyone left.
I know, I know. "It's just a show!" But this is ALSO a show that cares about food scarcity when it's convenient to the plot. In this same episode, Jaime assures Olenna that Casterly Rock will not stay occupied for long.
So sustenance is a concern for some of the characters on this show, but somehow not for anyone on Dragonstone, a barren rock consisting mostly of dragonglass and moody cliffsides. Are the dragons roaming offshore to get spare goats and shepherd's children to eat? If so, wouldn't that kind of negate Daenerys' whole plan of "Don't kill the common people so they like you better"? Nah, couldn't be -- the Queen of Dragons definitely isn't known for her string of terrible decisions.
You'd think that Melisandre would show up on Dragonstone for a reason, but uh, she really didn't do anything. At best, she sort of reminded us that she existed before heading off across the sea to avoid a slightly awkward convo with Jon and Davos about all that child murder she did. But really, she could have done something to help Daenerys out during the few weeks she was on the island. Doesn't she know magic? Like, deadly shadow baby magic?
Man, you know what could end the war without a lot of bloodshed? If a shadow baby were to say, shiv Cersei in the night. Boy, that would really come in handy. If Mel really needed royal blood for her dark magic, she's got her choice of Daenerys or Tyrion, both relatives of those who have sat on the Iron Throne. Even that weird stuff with Gendry and the leeches seems to have worked out eventually. Why not try like, anything other than nothing before leaving Dragonstone? You might argue that Melisandre is a little hesitant to use her powers after how terribly it went with Stannis and Shireen, but at this point a simple effort would be better than what she offered, which was... not much besides taking up a presumably nice room in the castle.
This is a small thing, but I still found it kind of jarring. Just before Daenerys agrees to let Jon Snow and his people mine the dragonglass, she remarks on her dragons. She named them after her brothers, who are both dead -- then she says "You lost two brothers as well?" This refers to Robb and Rickon Stark, but specifically leaves out Bran, who no one knows is alive. It's almost like Dany read the script and knows everything the writers know. Either that, or she forgot that Rickon existed like everyone else.
At this point, all of the Stark kids have had it pretty rough. These kinds of dramatic and traumatic experiences will change people for life, especially when they occur during the formative years. Bran's had his own trials, but he seems to have been suddenly drained of all personality and has lost any sense of social acumen. What exactly is it about being the Three-Eyed Raven that makes you think it's cool to bring up your sister's rape in casual conversation? Bran wasn't even like this the last time we saw him, but all of a sudden the dude has turned into Orin from Parks and Recreation. I get that he's grappling with a lot here, but it's like New Bran took a crash course in Euron's School of Showing Up Suddenly Looking and Acting Differently.
Taking everything into account, Davos is one of the best and purest hearts on the show. That means he will probably die in an awful way sooner or later, but apparently it also means that he'll let it slide when he meets the murderer of his sons. Remember, Tyrion was pretty much the mastermind behind the Lannister side of Battle of the Blackwater. You know, the battle where Davos' children were killed by the wildfire Tyrion told everyone to use?
When the two meet on Dragonstone, Davos isn't even pretending to be polite -- he earnestly shakes Tyrion's hand. They even mention being on opposite sides during the Battle of the Blackwater.
Davos is smart enough to know there are only a few people smart enough to defend King's Landing like that. It sure as shit wasn't Joffrey's idea to load a decoy ship full of explosives. Even if Davos were to acknowledge that it was war and it wasn't personal, it was still his own children who were killed as a direct result of Tyrion's actions. Maybe like a little hesitance or even the slightest hint of a grudge would make Davos a bit more than a lovable grandpa to everyone he meets. That's not to say that's such a bad thing.
Towards the end of the episode, Tyrion narrates the action as the Unsullied take Casterly Rock. It's a handy setup, helping to explain the battle strategy to the audience so everyone is properly prepared for it to go very, very wrong. Before we learn that Cersei and Jaime are a few steps ahead of Team Targaryen's armies, Tyrion explains that he left a little entryway in the sewers. Set up several seasons ago with an offhand mention, the fact that Tyrion rigged secret passageways in Casterly Rock is absolutely vital to the attack plan... which is why it's so baffling as to how he is only telling Daenerys at that moment.
At the time of Tyrion's monologue, Varys reports that the Unsullied have almost arrived at their destination. Meaning that Tyrion has been hiding his secret plan from his own queen for weeks, just so that he can tell it to her when it's most dramatically impactful for the show. Make no mistake, Tyrion's voiceover definitely helped viewers get a better understanding of what was happening -- but the timing didn't make any damn sense.
CGI wolves are expensive, no one is denying that. But at this point, most of them are dead, and the only one we should be seeing with any regularity is nowhere to be seen. Jon Snow's white direwolf Ghost was inexplicably absent at the Battle of the Bastards, and now the poor guy has been left behind while his master is on Dragonstone. There wasn't even an offhand mention of him, something like "Don't forget to feed Ghost while I'm gone, preferably with the throat of Littlefinger." Then again, mentioning Ghost would only highlight his absence.
According to one of the show's producers, Ghost had a scene last week, but it got cut. So the people behind Game of Thrones actively considered filling a plot hole, but decided instead to save all the direwolf budget for Arya and Nymeria. Not only has the show killed tons of fan-favorite characters, but it has now murdered hopes and dreams.
