It was the first episode that didn't make me want to stab Cersei with a knife. What she said actually made sense and Tyrion knew it. Jamie had a few great lines too but I don't remember him strangling a relative. Was that so?
Tywin and Arya was excellent again, too.

There was a little too much running around on glaciers and Dany being whiny again, but both storylines came around in the end.

The way it was presented, I doubt that any viewers consider Rikkon and Bran dead at this point. But do they still have anything to do this season or could they leave the solution to that hanging until S3?
