The Spoils of War & Dragon Fire

So, the thing that I had always wanted in life and didn't even know I was missing it, was to see a dragon leading an army of scythe wielding warriors on horses into a battle. Out of 64 episodes, season 7 episode 4, The Spoils of War, has become my new favorite. Before I get too ahead of myself, let us go back. 
First, Arya comes home and doesn't kill anyone. I really thought she was going to kill the guards barring her entrance into her Winterfell home. I really did. But, she was cool about it. I do want to see them grovel as she passes not realizing how close they came to death. She and Sansa acted just as they should have. They are sisters, but weren't that loving towards each other in their youth. They've grown up without each other and they both have stories to tell. I cannot wait for Sansa to tell Arya all she's been through and I wonder if more names will get added to Arya's list, namely Littlefinger. Bran is still being Professor Xavier cool but I might have to agree with Leslie Jones, he is on drugs. Can we say he's drunk with knowledge? 
Cersei is being Cersei though I do wonder what devious, devilish plans she has. I also wonder what her liver looks like. I mean, she doesn't drink any water and she's always got a glass of wine in her hand. Not little glasses either and not an appropriate amount of wine! It would be terrible if her liver gives out before someone can wrap their hands around her neck. 
Jon is getting his dragon glass and closer to Dany. She's leaning on his advise and learning to trust him. It would be so fabulously romantic if she weren't his AUNT!
I am concerned about Missandai though. Thinking back to the prophecy Dany heard in the house of the Undying, and knowing that someone will betray her for love, When Davos and Jon ask her about her life in slavery and she says that Dany would willingly let her return home, that plants a seed of doubt. Dany cares for Missandai a great deal, and it's been mentioned more than a few times this season that Missandai is her most trusted advisor...but is she? I mean, she's her translator and right hand, but does she advise her? That's really what Tyrion's role is. Greyworm is the head of the Unsullied forces and now she has Jon and Davos advising, so what does Missandai do exactly and could her faith in Dany be shaken this season? 
Finally, Drogo! When Bronn says listen, and you hear the thunderous hooves of the Dothraki horde in an open grass field! OMG! And then you see that dragon! I mean...shear perfection! The look on Jaime's face and the soldiers  quaking in their boots was perfect. When the Dothraki crouch on their horses backs simultaneously, I'll just say my throat was sore from screaming and my hands hurt from clapping so hard. The only thing that could have topped it would have been Cersie coming out on the field to see what was going on. 
Jaime is a fool. I don't know if he was aiming for Dany or the Dragon or both but foolish he was.
