This episode was amazing, as always. I just feel like Dany is sitting on the key to winning the war with Cersei as well as the White Walkers. SHE HAS DRAGONS!!! I get that Jon has to earn her trust, because she clearly is unsure if what he is saying is a real threat, but if he is right, does she want to risk that! Also, correct me if I'm wrong, but doesn't dragon glass get produced when dragon fire hits the earth or a certain type of rock or something. They LITERALLY have all the ammo that would be needed to take out the Night King, end winter, and take the Iron throne for THEMSELVES and rule everything TOGETHER!!! Why can they not see this?!?
Also..RIP Lady Olenna, I will miss your snark and fantastic acting!
