Just now got around to watch this episode. Enjoyed it very much, but what surprised me was how the show suddenly started to differ from the books in several aspects of the show.
A Clash Of Kings book spoilers
I think part of the motivation for these changes is to throw some curveballs to us fans who have read the books several times and know the story in and out. It worked for me, I loved this episode. And it's saturday already? Almost time for another episode?! Get in!!
