I think this is great television and bad Game of Thrones. So I'm just enjoying the watch and letting myself be giddy every time they dish up fan service. With that being said, allow me to put my thinking cap on:

What was the Hounds line to Gregor supposed to mean? Are we just to assume he was saying some lame religious shit? That seemed like a pretty big dud.

Also, they really needed GRRM to write these-- there are far too many characters with far too many connections in that scene, and there's a lot of a lot that goes unsaid that would 100% be said.

Like, Joffrey died and the Hound disappeared, and everyone is just like "oh, cool, he just is with these guys now and wants to have a little chat with his brother real fast."

Also, what the fuck is Cersei's plan here? If she didn't want to go North, why not just agree to the truce and avoid the double crossing? You don't think that they'll notice the lack of Lannisters in the North in a week? It's like D&D have gotten pretty good at GRRM level scheming, but they're applying great scheming to a shitty plan.

Also, what the hell is the outline of the next season going to be? Jaime can no longer Queenslay Cersei, which removes a great ending to both their arcs, and the White Walkers seemingly need to be dealt with mid season (or earlier?) to give time for everything to wrap up. That seems awkward.
