Back to the Starks. They have a choice between attacking Tywin or Jaime. Beating Jaime would release Riverrun from the siege, and beating Tywin would presumably do something else strategic. And either way, they need to cross the river at The Twins. Next week's opening credits had better cover all this. Oh! You know what I just realized? The map is at the beginning of the episode, the same way that in a lot of fantasy novels, the map is at the beginning of the book. I was just about to say, "I can't turn back to the beginning of the episode the way I would with a book," but I kind of can. Let's move on. The bridge at the river is controlled by a Lord Frey, whose charming soubriquet is "The Late Lord Frey." I guess he might be undead or something. That's kind of ominous, right? He's also one of the Stark bannermen, but "Some men take their oaths more seriously than others."
The discussion has to be paused when a guard drags a Lannister scout into the tent. Into the command tent? With the official War Plan Map on the table? That seems like a poor policy. Robb covers the map, but Greatjon points out that the spy won't leave the tent with his head. That's a fair point, I guess. He was in the brush, counting troops. And he says he got as far as twenty thousand. Given that that's two thousand more than Robb actually has, I think the Lannisters should consider educating their scouts a little better. Start with intensive courses in "counting" and "hiding better." Robb says that his father understands honor, mercy, and courage. Then he surprises everyone by saying, "Let him go." Cat stands, but Robb looks her back down. He turns back to the scout: "Tell Lord Tywin winter is coming for him. Twenty thousand northerners marching for him to find out if he really does shit gold." The scout leaves. Greatjon is furious. "Are you touched, boy? Lettin' him go?" Robb looks him in the eye. "Call me boy again. Go on." The Greatjon backs down. Seems pretty obvious, doesn't it? Robb is letting the scout go back to Tywin Lannister with inaccurate information. Now Tywin will expect twenty thousand coming for him when eighteen thousand are really going after Jaime. Good solid generalship right there.
