Funny, in my opinion all the characters are way too old in the series. Arya isn't 11 in the books, Sansa is. Arya is 9 if I remember correctly. In the series, Arya and Sansa look like 12 and 15. Jon and Robb are 14 in the book, at least 20 in the series. Ricken is 3 in the books, to me he looks like 5 in the show, and Bran is 7 in the books, and he looks like he's 10.
