It is particularly interesting how the show is juggling its personnel to fill in the blanks without having to introduce even more characters. In this case this worked really well.
Like Isaac, I am glad they did a little more justice to Stannis here, who was a tad one-dimensional so far.
And Jaime's breakdown was just fine writing and acting. Excellent.
The fire fight and Jon's little adventure were very close to how I always imagined them.
