Game of Thrones is many things, least among them is subtle about its weekly themes. It’s part of the experience, as we’ve seen it develop over the years, to watch D.B. Weiss, David Benioff and the rest of the writing team parse together stories from all over the world of Ice and Fire in a way that makes them fit together despite great geographical, philosophical and tonal differences. This week’s episode, “Second Sons,” is no different. It’s the kind of slower, more meticulous episode that digs a little deeper into the greater notions of faith and honor, love and duty. It’s also filled with moments both sweet and sour for characters we like, those we don’t and those whose true nature is yet to be revealed to us. It is on this note that we begin our weekly Blog of Thrones discussion of episode eight, a sweet and sour appetizer to whatever darkness lays ahead. From here, there will be advanced talking points from this week’s episode, “Second Sons.” Read on at your own peril.
