Man this season really sucks as far as keeping arcs flowing each episode. Only a few minutes got spent on Tyrion, Bron, Theon, Samwell, etc. Just a slow trickle of exposition leading up to their probably most important events so far. And yeah, Arya had a scene too (two actually) but it wasn't enough time to actually see what happens.
They really need to take a break from anybody closely related or engaged to Joffrey. He hasn't had anybody tortured or killed this season which is the only thing of any consequence that he does.
