"Season seven will be a never-ending game of 'Spot Arya.'"
Wasted NO time kicking that one off!!!

I liked that they called attention to that because i think a lot of people missed the callback, similar to how another "previously" flashed back the beheading of Ned and intercut his beheading of Will the NW deserter from the pilot

Joffrey always needed to slap a bitch…

Could also just be a staging thing. Everyone else giving her space. Helps accomplish that without her running up the steps or them crawling…. However there was seeding for the point you're making in last season's finale in the scene where Dany names Tyrion Hand of the Queen

Sam the Slayer, curer of greyscale??? You heard it here first.

I read this as guarded suspicion/anticipation of imminent hostilities with Lannister soldiers to force her hand to kill them all (I've had this same type of conversation with these same type of people before, I know where this is going) giving way to the realization that she has plenty in common with these guys…

A bit heavy on the radical environmentalist propaganda…

"Bolton Bolton Bolton Bolton Bolton!!!!!! Crispy yummy chewy Bolton strips"
Dogs don't know it's not bacon.

What if Sansa has arranged a marriage to Littlefinger?

So, I guess Dorne is gonna randomly show up at Riverrun next week. "Lannisters? Heck yes we'll kill some Lannisters!"

Last week's episode opened with the most serene sequence ever in GoT. It was like Clash of Clans before the goblins even show up! 2 episodes later will undoubtedly be the polar opposite.

That's also because book Jaime is focused on resolving the siege without ripping the countryside apart all over again, and spilling tons more blood on both sides. So the Kingslayer works through a crisis of conscience and once again ends up doing something generally despicable for what he considers to be the greater…

A popular theory is that it was simply offscreen dialogue about Margaery bring scheduled for the walk of atonement, and that there is no further loose thread. Cersei took that info directly to the Small Council. I'm not 100% sure though, it seemed a little murky. But then again, I dunno what else it could have been…

"Pushing 10 year olds out of tower windows is so mundane… I think I'll threaten to launch a baby in a catapult"

"The things we do for love" … An exclamation point on the already obvious fact that Jaime is right back to where he was in Season 1 episode 1.

The scene cut seemed to suggest Tyrion in Meereen, but that's probably misdirection. Here are some grounds in foreshadowing for wildfirebombing…
Cersei told Tywin, "I will burn our house to the ground before I [leave Tommen's side and let him be clawed apart in the middle of a political power struggle]" when she…

Arya probably drank the magic House of B&W water that seems to kill or heal depending on what the plot needs. It seemed from the blood trail that she made a pit stop there. And the blood trail continued because the Waif's face was still dripping, I guess.

Don't forget Theon's also guilty of killing and burning 2 young boys… Not shedding too many years for Theon's lost pork sausage.

I believe she may not have recognized it, being not even a teenager, and Jeor having left for the Wall years ago, and Jon's wolfshead pommel adorning the handle in place of Jeor's bear pommel. I don't believe Jeor giving Longclaw to Jon was mentioned.

Arya's plot armour is annoying because it's the only thing keeping her alive, when at this point what should be keeping her alive is character armour- the fabric and nature of her character which the last 2 years was supposed to be methodically forming into a highly trained killer who intimately knows how the Faceless…
