I was under the impression that the explosives were already down there, left behind by the Mad King for his ill-fated plan to burn the city to the ground. Of course, that just raises the question of why they didn't just get rid of all the wildfire beneath the various landmarks of the city in the years since then.
Still, I absolutely loved that scene. Just wonderfully choreographed.
I find the show is much, much better if you use Arya's scenes for bathroom breaks
This. THIS. They murdered their lord because he wouldn't get into a stupid war over a guy who VOLUNTEERED to take part in a battle to the death and lost, they murdered Marcella to piss of her mother, murdered her betrothed because he was in the way of them seizing power, and I seem to remember them burying some guy in the sand and using him for target practice at one point in the past too. I've been waiting for these pieces of human excrement to get theirs for ages, even resigned myself to the fact that I'd probably have to wait until next season, and now they're working with the protagonists?? FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUC-
Maybe Varys is just recruiting them to be expensive dragon feed.
Also, I've never been a fan of Daario, but even I was appalled at the way Dany treated him, especially coming on the heels of her forgiving Jorah Mormont.
Yeah, this makes a lot of sense:
Tyrion: You can't rule in Westeros with someone like Jorah Mormont at your side.
Dany (later): Oh, Johrah, I just can't get rid of you. Go find a cure and then come back to my side
Tyrion (apparently): You can't rule in Westeros with Daario at your side
Dany: Okay. Hey Daario, the guy who's been completely loyal and who loves me for me instead of as a creepy replacement for his ex-wife. You're an inconvenience. Get lost. Also, while we can never see each other again, I'm going to abuse your declaration of loyalty to force you to stay behind and clean up my mess in Mereen while I'm off doing what I REALLY want to do. Because using the people who love me makes me a cool badass who is still sympathetic as long as I pretend to feel bad about it afterward.
Daario: Maybe I could just stick around as some nookie on the side?
Dany: Of course not. Despite me being just fine with that when I was getting married for political reasons in Mereen, it's out of the question when I get married for political reasons in Westeros. Because the show needs to get rid of any romantic loose ends.
Either that or I'm dumping you for Yarra, given all the pointless lesbian innuendo the show shoehorned between us in the previous episode
Still, that "blowing up the sept" scene was really cool...
