It was plausible for Cersei, Joffrey or even Tywin to be behind the order, since any of the three of them could have done it and all seem to hate Tyrion. (Tywin would have had to send a rider ahead, but he wasn’t far away because he only missed the first half of the battle of Blackwater.)
Cersei was mighty pissed at Tyrion for having Myrcella (sp?) sent away, before the Battle of Blackwater.
The ship Sansa was looking longingly at – that was Littlefinger leaving? I thought she was just playing her “let’s imagine” game again.
Because for the majority of the first two seasons, we’d been under the impression that Cersei had been pulling Joffrey’s strings.
Didn’t he say he was a Karstark? And wasn’t it Karstark (the guy that Robb beheaded last week) the guy that offered his son’s services to take back Winterfell?
Yes, that was Littlefinger leaving. It was explicitly mentioned to be Littlefinger’s ship in the previous episode and now we were explicitly shown the rear of the ship.
It was made abundantly clear that Cersei has no control over Joffrey when he had Ned Stark executed.
He lied. And no, it was Roose Bolton who offered to have his bastard take back Winterfell.
He said he was a Karstark, and then he said he was a liar and was lying about everything he just said.
I thought we were supposed to think Theon was imprisoned by the Boltons all along, only to get the rug yanked out from under us. Fooled you! It’s really Unexpected Lord XYZ!
Lord Bolton (the guy with a flayed dude on his flag) said his bastard would go to Winterfell..plot stuff happens…Theon gets tortured. That’s not much of a twist, is it?
Forgot about marrying off Myrcella entirely.
There was a Littlefinger bird symbol on the sail I think. Same one he wears around his neck.
It was Ros and Daisy. Ros was forced to beat Daisy and Joffrey had her sent to Tyrion but I don’t think she was dead. Do a, obviously, wasn’t killed either. Later, Cersei took Rod into her custody, mistaking her for Shay.
Last episode there was a scene in which Cersei asked Littlefinger to persuade Tywin to take action to thwart Tyrell scheming.
Rosie Bolton currently has Jaime and Brienne. He’s one of Robb’s few remaining amendment and he’s in charge of Harrenhal.
He had a line on that very scene. He might be a rare appearance but at least he’s around more than the direwolves.
Thanks for the quick and detailed answers everyone. I knew about the bastard sons, but somehow missed that Gendry was one of them. Too many bastard characters on this show! 
To further my embarassment, I’d like to publicly admit that I actually like Stannis. Sure he has an abrasive personality, but he seems to have a legitimate claim to the throne and he has a no-nonsense way of getting things done. And really, who among us hasn’t been seduced by a red she-devil once or twice? I would print up “Team Stannis” t-shirts, but I fear nobody else would want one.
I liked Stannis quite a bit after the battle of Blackwater, dude was in front of his men kicking all kinds of ass.
I suspect Roz wasn’t the first Prostitute Geoffrey has killed, just the first one we saw and whose name we knew.
I feel dumb because I never realized the Wall was made of ice. I thought it was build by some long forgotten ancient civilization.
I liked the turn Jon Snow and Ygrite(?)'s story took. In a world were everyone has an agenda, having some characters with pure motivations would be refreshing.
Speaking of which, Arya is awesome and I think I would like this show just as much if it just followed her and her story.
Why do you think the two are mutually exclusive?
On the contrary, I think it’s very clear from Littlefinger’s speech to Varys that this is Joffrey’s first time. He was very eager to try a new experience and is very grateful to Littlefinger for finally allowing him to do it.
I’ll note that Tywin hasn’t delivered on his promise to stop Joffrey from doing what he likes.
Maybe he’ll do something once his spies on the royal janitorial staff tell him about having to remove Roz’s corpse from the king’s bedchamber.
If there’s one thing Tywin cannot abide, it’s prostitution.
Stannis is the mannis.
He rolls around with a crew of badass smugglers and pirates and a sexy foreign witch.
He promotes people based on merit, not on who their father was.
Her refuses to not give people credit for their accomplishments, but he also refuses to not insult people when they deserve it. He literally thinks it would be unethical not to insult them.
Stannis has sex on a table shaped like a giant map of the country he plans to conquer.
Stannis blows a load so hard that 2 weeks later the woman gives birth to a fully grown shadow man that assassinates his political rivals.
His pre-battle inspirational speech was one sentence long and was really more of an order than a speech. It was still the most inspiring thing we’ve seen on the show so far.
Stannis is always angry. You’d be pissed off too if you had to live in Westoros. It’s kind of a terrible place.
I have no idea how people keep track of this. My experience of this show must be seriously impoverished.
He also has the craziest code of ethics, which make him fun to watch. Like how he cut off Davos fingers for being a smuggler, even though he was smuggling food in to Stannis.
In fairness to Stannis, I think the finger-cutting was a punishment for Davos’s past history of smuggling, not the smuggling that saved the castle.
Yeah, he even told him “one good act does not erase all the past bad ones”.
