This is my last try screaming into the void and likely my last post on Reddit. I just read these leaks for the first time. I know nothing but what has already been shown to us in the show and what lore says. What if, and all my ideas are apparently crazy, some of the leaks that seem to directly contradict the other ones don't at all? Some lists are looking only at the seemingly surface motivations and missing the underlying ones, whereas other lists get the layers of it. I think some of the Longacre predictions were filmed but not kept in because they may have made the answers too easy, and he may have been right about the original placement of the dragon death. The dragon death seems so abrupt and strange in E4. I think it was moved up an episode to speed Dany's anger progression in a believable way.
Where is Arya, and why does Cleganebowl sound so disappointing? It all may be hinted at based on what we've already seen particularly in E4.
Back up to The Night King kill. What is NK after? The actor who played him stated he wants revenge, and that he was out for a certain person. Most people assume Bran, or solely Bran. But look into the history of the Starks and the White Walkers. A Stark ancestor is said to have personally killed the former Night King and Night Queen. (There was one, just the once.) The aerial view of the wights in formation looking like the Stark sigil suggests who he wants revenge on.
Arya was touched by the NK and nothing happened to her. Really? Watch E4 again. Look at her. My husband said she looked "waxy." I thought she was looking pale. There have been effects of being touched by the NK. Think about it, what would make the most fitting revenge on The Starks for what they did all those years ago than to make The Stark's own descendent daughter doomed to be the new Queen? She avoids company all episode, until she's leaving Winterfell. She skips the feast. She leaves -- forever, she says -- but says no goodbye to Sansa or Jon? Look how stiff she is with Gendry before he mentions the Lord stuff. That's just her convenient out. She was going to dump him anyway. I don't think their relationship was purely sexual. Look how sad she is during their interaction. I don't think she wanted to have to see him at all. He sought her out.
As far as Cleganebowl, it all boils down to "they." Who is "they?" Read the progression of Lightbringer's activation and what happens afterwards. (Lightbringer?!! Yeah. read my other crazy posts). First, the sword is used to kill a lion. I've realized some people on Reddit are pretty damn dense even when something seems obvious, so here: Lion indicates Lannister. Arya's remaining "green eyes." Not saying she will use the sword on a Lannister and not kill a separate Lannister in an entirely different way and the sword's kill will be via someone else's hands. But the sword will probably will be used, by someone, on a lion. Maybe Jaime runs Cersei through. Maybe Arya's wearing his face, as some suspect. I don't know. Maybe Jaime gets killed. Maybe both.
What does she mean by "probably" in her scene with Hound? Many take it to mean she is going to kill The Hound. What if: she expects to already be dead before she has the option whether to kill him or not? Read what happens after Lightbringer's activation. Azor (explained in my other posts) stabs a "monster." What is The Mountain now but not that? Read what happens to the monster. It is pretty horrible. The Hound, with all we know about him, wouldn't afford his brother the mercy the brother never afforded him?
