I thought it was a fair enough opening.
NORTH
Brienne is the best knight, and little Podrick on his first big-boy fighting adventure was adorable. I'm eager to see where they will take the North plot. There were set pics of Brienne in Riverrun and Jon fighting what looked to be Boltons. Maybe Sansa links up with Jon, and goes with Brienne to get Tully soldiers for reinforcements?
I also enjoyed a joke I saw on the twitters: "Sophie Turner finally had to look up to talk to someone in this episode!"
THE WALL
This is a lot more than Davos asked for. I don't see how they'd get themselves out of this without Melisandre resurrecting Jon, and the Night's Watch bowing down in reverence like the Dothraki did for Dany. Maybe they escape during a White Walker attack? Regardless, I didn't expect Jon to be jumping up this episode. Melisandre glamour/age theory confirmed -- at least on the show. I wonder if her real age will have any impact on the backstory. Like, how long she knew the end times were coming and the manner of her birth. There's a more outlandish theory that she's the bastard daughter of Bloodraven and Shiera.
BRAAVOS
Proceeding smoothly into Arya's book plot, no major deviations or surprises.
DORNE
Well, that escalated quickly. A shame Doran and his actor were not given more material to work with before exiting the show. I guess they want the Sand Snakes to be more prominent. Maybe for the sake of having more high-profile female characters in leadership positions. As always, however, execution was incredibly clunky and the pace was too fast to have any kind of weight to it. What are you guys even going to do? Dorne's army is small and best utilized in Dorne itself, on the defensive.
KING'S LANDING
Margaery scene, okay, she's still there. How nice.
Cersei and Jamie. "Honey, I've got good news and bad news. Good news, I brought Myrcella back! Bad news is... well..." I suppose their scene together was fine, but I really liked the scene where Cersei watches the ship come in. Lena had some really good face-acting going on the whole time. I actually felt sorry for her.
MEEREEN
Everything is awful and on fire. I guess it's just a good scene to summarize the situation / trap the boys in the city. Not much else of interest.
THE DOTHRAKI AND SER JORAH'S TERRIBLE ROAD TRIP
Dany's scenes are a bit ridiculous, as all the Dothraki present would have known Khal Drogo and attended their wedding. So Dany's identity should've been known from the start. But I suppose they wrote it that way for all the people who didn't watch season 1. She's largely untouchable due to Dothraki laws, so at least she won't be abused this time.
Jorah and Daario could be interesting road trip buddies, but it depends on how the writers characterize Daario as we move forward. If they don't give him any extra layers beyond "arrogant playboy warrior," then he's going to get boring quick. And sure, Jorah. You just happened to find that ring within seconds. YEAH, OKAY.
