"Episode 3 is in part an aftermath episode, where you settle and everything takes a turn toward the second half of the season," Alex said. "Joffrey's death is a beginning. Ned Stark's death was not an end -- it was a beginning. It's when the show began. All the deaths are like that, and Joffrey's is no different. Joffrey's death affects the show through to the climax."
Yeah, you’d expect the death of a king on a show called Game of Thrones to be a pivotal moment. Who killed Joffrey? Where did Sansa go? What happens to Tyrion? What’s next for Queen Margaery? Who will be the new king/queen/ruler and how long will that work out? The Iron Throne is not a comfy chair, that’s for sure.
