Kathy Campbell joins Jason and Monty in our spoiler-filled rewatch of season one of “Game of Thrones.” In this episode, we stay on brand by frustrating pedantic fans with our utter failure to recall what Littlefinger is up to or why he had Jon Arryn assassinated. Also, it’s the triumphant debut of sexposition; debuts for Sam, Bronn, Gendry, and the three-eyed Raven; Arya stays true to herself; and we pay tribute to Ros, the hardest-working whore in Westeros.
