I like to read about Jon Snow and Arya. Arya is brave and fair girl. And she doesn't divide people into "nobility" and "rabble". She hit Joffrey, because he wanted to kill Mycah. So, and I can't stand Sansa, when Arya is the polar opposite of her. Jon doesn't want to go south and it is a positive surprise for me. I like Jon's chapters, 'cos the Wall, Night Watch and wildings are more interesting for me than palace intrigues. Jon himself is purposeful and he seems to me more old than Robb, while the age difference between them is not big.
