Bran whines a lot, but it’s justified because he can’t walk. When will he not be entitled to complain anymore? According to the Eventual Mitigation of Severe Tragedy Formula Union (EMOSTFU), the grace period for a tragic event is equal to twice the amount of time you lived without the tragedy. Thus, in Bran’s case, it's two times however long he possessed the ability to walk. Assuming all Stark children could walk the instant they were born, Bran can whine until he’s at least twenty-one. That's a long time. Crap.
He’s also a jerk to Old Nan, which is definitely not justified. She’s just trying to help and advise him by telling him about the Others. Thus far, 100% of people who have ignored wise old advice have been turned to zombies, so Bran should really pay attention. Instead, he's interrupted by Tyrion’s arrival. Despite Tyrion’s handicapped saddle gift, the direwolves still hate him. Gee, I wonder why. Tyrion is lucky that Bran doesn’t remember who pushed him, or else he wouldn’t leave Winterfell alive.
At the end of the chapter, Robb and Bran share an intimate, non-homosexual non-incest moment, showing that their parents’ absence is taking its toll on all of them. Come on guys, get a grip. Starks don’t cry. Besides, this is the north, where tears freeze before they reach your beard.
Eddard is investigating the circumstances of Lord Arryn’s death. Why did Cersei want him dead? Is the Grand Maester in on it? These questions are far too nuanced and complex. Eddard, with all his duty, honor, and hard work, is built more for straightforward problem solving. He’s a firefighter, not a detective, whereas Littlefinger is an investment banker, Robert a washed up football player, Cersei a trophy wife, Varys a CIA director, Pycelle an elite French chess player, and Joffrey the spoiled rich kid who will one day get his comeuppance.
Eddard sees Arya practicing hard at “dancing” before he’s summoned by Littlefinger, who leaks to him the identities of several informants who keep tabs on him. It’s like Eddard is peering down the rabbit hole of King’s Landing politics and finally realizing that he is way out of his depth. This place operates on an entirely different set of rules, the most important being “trust no one.” A wise man once said, if you can’t spot the sucker in the first half hour at the council meeting, you are the sucker.
