After a few weeks of murdering slavers and flaming sword fights, "The Climb" was a rare episode of build-up in a necessarily abrupt 10-ep season. The big action sequence was a literal realization of the title, and we ended on not uncharacteristically doom-filled monologue. As Game of Thrones goes, fairly typical.
It's also always interesting to look at the fortunes of the respective houses (two of them anyway, last night was Daenerys-free), namely the Starks and Lannisters, whose conflict is the wellspring of everything since King Joffrey ordered Ned beheaded. And as it so always is, the takeaway for each is ambivalent at best. Fleeting moments of pleasure or satisfaction give way to the grinding realization that happiness probably isn't in the cards.
What, too grim? Have you listened to that theme music?
