Our re-watch of the first season of “Game of Thrones” reaches its surprisingly key second episode, where Ned tells Jon he’ll explain his parentage later, Joffrey decides to have a bit of fun with the butcher’s boy, Dany gets some intimacy tips from a handmaiden, and the direwolves have perhaps the most screen time they’ll ever get. RIP Lady. (Note that if you’re looking for a spoiler-free look at “Game of Thrones”, this isn’t it. We discuss where the series is going up to the end of the penultimate season.)
