After the celebrations died down following King Joffrey’s death on last week’s Game of Thrones, we realized that the show has now given us another big mystery to contemplate: Who killed him? Thankfully, we won’t have to wait long to find out.

According to Game of Thrones director Alex Graves, who directed Joffrey’s death in Season 4, Episode 2, along with four other episodes this season, the answer as to who his killer is will come sooner rather than later. “You find out in the season is all I’ll say,” Alex tells the Huffington Post. And also, the thing I would say about Joffrey’s death, like any death on Game of Thrones, it’s an end, but it’s also a beginning of a story. The same with Ned Stark’s beginning.”

Now for those of us who don’t want to wait, does Alex think we’ll be able to figure out who the murderer is if we rewatch the episode? “No, if you watch it again you won’t catch it,” Alex says, before disclosing, “But if you analyze it, and you know who did it and how they did it -- which is another whole thing — it tracks. And that’s all I can say.”

Alex seems to be confirming that the murderer in the show is the same as the murderer in the A Song of Ice and Fire books, so those of us who’ve read the books already know, but those who haven’t will know soon enough!
