9. Sam The Greyscale Slayer
This was, in comparison to the more seismic events elsewhere (and in terms of time devoted to it, too), a rather small scene, but nonetheless an effective one.
As we pick things up at the Citadel, Archmaester Ebrose gives Jorah and his greyscale a good checking over, with the 'explanation' given that the cure was rather miraculous (which Ebrose of course isn't buying).
Although the show keeps pointing out how dangerous the procedure was, it does still seem startlingly simple to cure greyscale in such a manor. But it's a minor quibble when it means Jorah is indeed now cured, and can return to his Khaleesi's side, likely to die a more noble death (and, if Jon's still at Dragonstone when he gets there, perhaps set about gaining redemption with his family).
The brief goodbye between Sam and Jorah was one of those nice little character moments Thrones throws us every so often, especially in seeing the now cured Jorah being able to touch somebody. It also sets up the rest of Sam's Citadel storyline, as he's given a bunch of old texts to translate - where he might well find more key information that everyone expects him to discover, although it might not make for compelling viewing.
