At last, a satisfying and shocking killing in Game of Thrones for everyone to enjoy. After death coming down on Stark after Stark, and the villains suffering only a lost hand, we get to celebrate the poisoning of one of the most despicable characters in the series and indeed in all of television: the just-married King Joffrey. George R. R. Martin tweeted "You're welcome" after the show last night, and millions were thankful indeed that we won't have to see this sick vicious twit of a character again.
But two intriguing questions ensue - actually one question, in two parts: What will happen to Tyrion, denounced by Cersei as the killer, and who really killed Joffrey?
Tyrion clearly didn't do it. Jamie and Tywin will likely see this, once they get over their shock, and I doubt if they'll let anything really bad happen to Tyrion, whatever Cersei's true beliefs. (I've read only the first novel in the series, so I have no knowledge of what will happen. Given, of course, what has already happened, anything is possible.) Indeed, the early scene with Tyrion and Jamie suggests that the two may have the beginnings of some real rapport.
So who did the deed, if not Tyrion? There are motives everywhere you look, especially with the Starks. Sansa has more than ample reason to want Joffrey dead. Did she act on it? I don't think so.
Was the killer on hand at the wedding party, to witness his or her deed? Probably - it's much more fun that way.
Is the killer someone we don't know, an agent from the north, or maybe Daenerys? Possibly, but it would be more fun to already have seen the killer, in plain sight, maybe even a moment or two before the deadly cake event.
I'm putting my money on Oleena, who couldn't have been happy, deep down, about her beloved Margaery married to Joffrey, despite the power that would give the Tyrells. But it's also not clear who will wield the power now with Joffrey gone. Will Margaery, be Queen? Will Stanis have a new claim to the throne? If Joffrey's death gives Margaery more power, then that gives Oleena a pretty powerful motive.
Whatever comes down the road, we should be for some wild times in Game of Thrones, and we haven't even gotten to the dragons and the ghost hoard.
