With its battering rams, swordfighting and ships going up in green flames, "Blackwater" maximized (sans dragons) the whole outsized medieval fantasy aspect of "Game of Thrones," the one that's probably the primary impression of the series maintained by anyone who hasn't yet seen it. It was impressive and messy, even though the show saved some cash by having Tyrion once again pass out and miss a crucial part of the clash (this time around, at least, he got to first heroically rally the troops and see some action). It was the big moment to which the season had been heading, the equivalent of last season's penultimate installment in which Ned Stark (Sean Bean) lost his head in a public execution for treason.
"Game of Thrones" is so focused on action -- not just literally in the sense of combat, but in terms of things happening and narratives moving forward -- that it can seem emotionally icy, its characters already a touch alien thanks to the brutal world from which they come and seeming more remote as the show packs in additional factions and storylines moving forward, leaving less time to get attached to any one figure. "Valar Morghulis" grounded the drama a bit by dwelling on what's already happened and the price that many of these people have already had to pay.
The top priority of "Game of Thrones" is never going to be in-depth character development, but that doesn't mean that the population on screen can't give the impression of being complex even if their every facet isn't going to be explored. "Valar Morghulis" demonstrated how susceptible and human seemingly otherworldly creations like Tyrion and Daenerys Targaryen (Emilia Clarke) are at heart. For Tyrion, that instance came after he woke up in bed to learn that not only does he now have a scar across his face, his ruthless father Tywin Lannister (Charles Dance) has arrived to save the day, displacing his son from the position of Hand of the King that he'd so come to enjoy.
"I like it more than anything I've ever done," he told Shae (Sibel Kekilli) in a crushingly sad moment after she asks him to run away with her -- like Daenerys, he's pulled back to something that punishes him and that may destroy him, because he knows it's the place in which he belongs. He tries to push her, the only other thing he loves in his life, away as well in a fit of self-laceration, but she sees through him, knows what he needs, and stays.
