1) Jorah the Andal finally did it. It took him six seasons to muster the courage to spill but spill he did: "All I've ever wanted was to serve you. Tyrion Lannister was right. I love you. I'll always love you. Goodbye Khaleesi." Good for you Jorah, good for you. It's probably unlikely but it would be great to see him actually find a cure for his greyscale and be with Daenerys when she marches into Westeros.
2) So it appears that the White Walkers, the most fearsome forces of evil in the show, were created by the Children of the Forest. This important detail was revealed in one of Bran's flashbacks. In the scene, the Children of the Forest can be seen huddling and talking while a male human is tied to a weirwood tree nearby. One of them approached the human and slowly stabbed him in the chest with an obsidian blade (dragonglass). The human's eyes started to glow implying that that was the beginning of his transformation into a White Walker. This also means that the man is the very first White Walker. He would turn into the Night's King.
Why did the Children of the Forest create White Walkers? The answer lies in one of the Children's answer when Bran woke up from his revealing flashback and confronted her about what he saw. "We were at war. We were being slaughtered. Our sacred trees cut down. We needed to defend ourselves," one of the Children answered. Defend themselves from whom? From men.
From this revelation, several more questions arise. We now know that the Children created the monsters as fighting machines against mankind. But why is it that the White Walkers are also killing the Children of the Forest? Don't the Children have the means to control the White Walkers? Maybe they used to be able to control them but lost it? Why did the White Walkers turn against their creators? But then again, creating your own doom is the main theme of the series.
The White Walkers have now turned into a seemingly insurmountable army gearing to invade Westeros.
3) Hodor, the gentle giant, is now dead. And we now know the origin of his unique name. It's a tragic ending for one of the show's most beloved characters. There have been a lot of innocent characters in the series who didn't deserve what happened to them or how they were killed. Hodor's demise is one of the most heart-breaking. Rest in peace, ye giant.
4) Ramsay Bolton didn't appear in the episode. For the time being, the young Bolton's place as a hated character was replaced by Euron, the douchebag uncle of Yara and Theon Greyjoy. Euron wants to rule over the Iron Islands and plans on joining forces with Daenerys Targaryen to conquer Westeros. How much of a douchebag is this man? Here's what he said when Yara and Theon escaped: "Where are my niece and nephew? Let's go murder them." And let's not forget that Euron killed Balon Greyjoy by throwing him off a high bridge.
5) Arya Stark is still out in Braavos learning how to fight with a wooden stick. It's kind of disappointing to see Arya's story get repetitive over the last several episodes.
6) Sansa Stark is now a woman. She showed this when she confronted Littlefinger and held her own in a tense game of wits. And then there's the fact that she's actively participating in the plan to gather an army big and strong enough to retake Winterfell from the combined forces of the Boltons, Karstarks, and Umbers.
7) And then there's Tormund Giantsbane trying his very best to win the elusive heart of Brienne of Tarth.
8) And there's Meera Reed. This girl is a badass. She speared and killed one of the Night King's lieutenants. The only other person to ever accomplish this feat was Jon Snow.
