Fair enough.

Fox has always been broadcast over the air.

The blade had nothing to do with Bran becoming a cripple or the Three Eyed Raven.

Maybe, but what happens when they run out?

Maternal lines matter, albeit secondarily, when it comes to royal ascension.

He's a cripple because Jaime pushed him out of the window. The dagger had nothing to do with it.

Who kills Sansa so that Arya has access to her face?

But "The Fireworks Factory" is something that has been dangled in front of you for the entire length of the series. Blackwater and the Sept had explosions and fire, sure, but they aren't what we've been waiting for ever since the end of Season 1.

Just something to waste plot time, really.

She's going to straight up marry him. She doesn't seem concerned at all about the appearances anymore. Remember last week when the servant walked in on them?

And Arya would need access to Catlyn's face to do that.

Um, because the White Walkers will kill everyone, including the commoners?

We need more Hound. I want him to reconnect with Arya. Arya, Brienne, Hound, and Pod. Sounds like an excellent band.

In the next episode, Randyll will suddenly remember that he had an awesome sword and then go home to fetch it. At that point, he will notice that it is missing and curse the skies.

Yes. It was an instruction manual.

The Bank still might fund Cersei's enemies after that display.

The Dothraki follow Dany because of the scene at Vays Dothrak, where she burns the temple down and walks out unscathed.

This skirmish was a shock and awe tactic. Everyone knows that Dany has dragons, but she hasn't used them in battle (in Westeros, at least). I can assure you that Cersei will have a LOT of trouble keeping people in her armies if they fear dragon-fire. Now that they've seen it, Lannister armies are going to tuck tail…

Sam took his father's sword, knowing that it was Valyrian steel. I believe for the purpose of learning the secrets of manufacturing it so as to arm the North.

That's what scares me (from a story perspective). He needs to go, but I have a sneaking suspicion that he's going to beguile Sansa in some way and she's going to do something stupid that takes the plot somewhere lame for a while.
