Littlefinger says he came here directly from Renly and Tywin shares the rumor he heard about how Tywin died: "Murdered by a woman, I hear." That's not entirely wrong, really. Arya stands behind Littlefinger as he talks about dark forces. Tywin thinks men love to blame demons for their own screw-ups. Littlefinger thinks this could be an opportunity, which Tywin ridicules as too obvious. Obviously it's an opportunity. Anyone can tell that! But Littlefinger has a specific opportunity in mind. He points out that the Tyrells are up for grabs. And there are more of them than just Loras and Margaery, although they're the decision-makers. Loras wants revenge and Margaery wants to be queen. Tywin points out that they're both traitors, especially Loras, who actively encouraged Renly to declare himself king. Littlefinger suggests punishing their treason "one day" after defeating Stannis. Arya brings Littlefinger more wine and he seems to recognize her. But then he has to concentrate on the possibility of riding to Highgarden on yet another errand. Tywin dismisses Arya. As she leaves, Littlefinger starts to tell Tywin that he met with Catelyn on the directive of Tyrion. Are you following all that? There were a lot of names in it. Tyrion Lannister, Tywin's son (the short one) told Littlefinger to go meet with Catelyn Stark without the knowledge of Cersei. And now Littlefinger's making sure Tywin knows. "Why?" "He had an interesting proposal for her. Concerning her daughters." That offer was "We'll trade Sansa and Arya Stark for Jaime Lannister." Arya leaves the room, which can't have been easy, considering the topic of discussion. And then we don't get to see what happens, which I personally object to. This isn't the book! Just because Arya's not there doesn't mean we can't listen in.
Oh well. Back to the snowy lands north of the Wall, where Snow is creeping around a rock outcropping. The other rangers do the same, although they do it around different outcroppings. Eventually, they decide they're in position and we see that they're surrounding a wildling camp. One of the rangers shoots a wildling with a bow and arrow. Time to attack! Wildlings get killed! One of them runs and Snow grabs her. But when he rolls his captive over and prepares to stab her to death, he discovers that it's a girl! So now he wants to question her. Qhorin says wildlings bite off their tongues rather than talk, so he thinks Snow should just kill her right now. In fact, she answers the first question right away: her name is Ygritte. And Snow tells her his name: Jon Snow. Qhorin looks on and I get the feeling he wants to be rolling his eyes. She recommends burning the bodies of the wildlings they just killed. Qhorin thinks that's a ploy to get them to build a big fire that will just draw more of them. She says she wants the dead bodies burned so they don't come back to life. Also, there are hundreds and thousands of "free folk" through the pass, so they better watch out. She won't say what's in the mountains that made all the wildlings (or "free folk" if you insist) move up there. Qhorin asks if they mean to march on the Wall and now she clams up. She unclams long enough to admit that she's heard of him. He asks, "If your people captured me, would they take me prisoner?" Nope! He'd get killed right away... or maybe slowly. He says they have no food for her and can't watch her. And they can't let her go because she'll go to Mance Rayder. Snow says he'll do it and Qhorin takes everyone but Snow off to the top of the mountain. So he's leaving Snow alone with this hostage that he's already shown reluctance to kill? Seems like an odd choice.
