Syrio told Arya to chase cats all day. This seems like very obvious foreshadowing, so maybe Catelyn gets kidnapped in the mountains and Arya has to find her. Arya had just caught the Moby Dick of cats, the infamous black tom, when she suddenly sees Prince Tommen and Princess Myrcella having sex. Before Arya could hide, Myrcella spots her. Tommen says “the things I do for love” and pushes Arya out the window. Somewhere in the distance, a wolf was howling. Crows circled the Red Keep, waiting for corn.
Myrcella, Tommen, and their guards, being typical pompous highborn assholes, mistake Arya for a beggar and collectively look down on her. Arya panics and escapes via waterdancing, but quickly gets lost in the castle. This allows her to overhear a conversation between two mysterious men, with topics ranging from Dany being pregnant to the possible assassination of her father. One of the men is Varys, because he talks about obtaining fifty more magical CIA surveillance birds. I have no idea about the other guy, but he is also familiar with King’s Landing politics. From the names they mentioned in the conversation, the other guy cannot be Eddard, Stannis, Lysa, Loras, Littlefinger, Tyrion, Tywin, or Jaime. I believe this guy is the mastermind in the game of thrones. Everyone else is just a pawn. Based on exhaustive analysis, I have concluded that this man is GREGOR.
Eventually Arya finds her way back but Eddard does not believe her story, even though Arya doesn't seem like the type to just lie and make stuff up. In other words, she’s not Sansa. Listen to your wise and awesome daughter, you stupid Hand.
Jorah the mole reports that Dany married The Rock and is pregnant with Rhaegar 2.0. Führer Bob has a final solution to the Targaryen problem, but Eddard protests because he feels squeamish about killing children. Even though Eddard admirably champions his principles, when it comes to the Targaryens, Robert is as difficult to budge ideologically as he is physically. Bob has a point, because letting Dany and her son live would be taking a stupid, unnecessary risk. The council agrees and begins discussing possible assassination methods. Robert doesn't want to poison her, because it would be too cowardly. So there exists some sort of courage scale in King Bob's head where "poisoning" ranks lower than "killing the unborn child of a teenage girl."
Child murder proves to be the deal breaker for Eddard, who resigns his position as Hand. The bromance between Ned and Bob is over. Eddard came south, picked up the pieces to a huge, confusing puzzle, and failed miserably at putting it together. Now, he's finally free. The Starks are headed back north, where they will arrive at Winterfell happy and rested. Eddard will discover that Catelyn and Jon have also returned, and have grown to love each other like only a mother and an illegitimate bastard son of a nother woman can. There's no violence or fighting. It's just one big happy family reunion.
Clash of Kings and Storm of Swords are just very, very misleading titles.
