The bit about a First Man turned by the Children of the Forest is what Bran saw in his vision. So I believe that more than a legend told by one of the Wildings.

The son of the former king beat up the guy who killed his father, so it makes sort of sense.
What? That guy didn’t kill his father. Euron did.
Sorry, you are right, the guy he beat up wasn’t Euron.
He is still son of the former king, and setting off on a heroic rescue.

Chronology
Battle at the Trident where Robert killed Rhaegar, which Ned mentions to Ser Arthur Dayne.
Sack of King’s Landing, the rape of the first Mrs Rhaegar and the murder of her children by the Mountian
Eddard Stark leads his Army into Dorne to mop up any remaining resistance (the Dornish Army had supported the Crown), which is where he finds Lyanna, who has given birth recently and who croaks not long after. This is where we meet Aegon/Jon.
So probably by the time the littlest Aegon was born, the littler Aegon was already dead.
Ah yes, tower of joy was after the sack of KL. Thanks. So did the Kingsguard know Rhaegar was dead? Did Lyanna? Not sure we have that info, but most likely yes.

It’s unfortunate that Theon’s plotline has become (even more) tangential to the story
I think Theon will be more than a tangent next season. With Euron heading to Essos to retrieve the Golden Company, Theon has a role to play. I’m guessing he’ll kill Euron and rescue Yara, who will take command of the Iron Fleet. Theon will then use the Tyrell gold to hire the Golden Company himself and bring them to Westeros to attack the Lannister army, saving some major character in the nick of time.

Another thing occurred to me: I actually expected the wight to be dead when he opened the box, thus making them all look like fools. If the white walkers can survive non-freezing weather, then what’s their hold up? Is it that they can only resurrect the dead in the cold, or is their effectiveness dimished in some other way in warmer climes?
That showed that the wights could survive at least for a time down south. Not that the white walkers that control them can.

For example: were Arya and Sansa faking the conflict the whole season? At some point they plotted off-screen to kill LF. Was this before they started fighting, or just before the last episode? If it just before the last episode, then how did Sansa change her mind so drastically? Or was Sansa plotting the whole time, she just didn’t let Arya in on it until the very end? Or did Bran orchestrate it? Maybe there’s some series of conversations that would make it all make sense, but I’m not sure what that is.
What I got from it was LF caused his own demise with the little game he explained to Sansa. She knew Arya never wanted to be a lady so she could reject her worst case. Then she played the same game with LF.

Yes, but we still don’t have a clue as to motivation. Is he just a Berserker in the Saberhagan mold or does he have an end-game of his own?
What motivation does a sword have?

This scene was one of my two biggest gripes of the episode. Other the unnecessary and unrealistic "It’s gonna be Arya…psych!!! (which, I understand, is a TV thing), I don’t see why Littlefinger didn’t go “Prove it” for all his charges.
LF: “Prove it”
Sansa: “Bran says so because he’s creepy and magically knows the past”
LF: “Prove it”
Bran: *some accurate quote from the past that only he and LF know"
LF: “That’s a pretty cool quote you just made up. Again, prove it.”That kind of conversation could have gone on literally forever. I can see how Sansa could trust her family over a schemer (even if he was on her side) but nothing in that whole ordeal seemed anything more to me than a giant he-said-she-said.
That’s the great thing about having a title and supreme executive power, no due process! He’s guilty because she said he was. And it’s not like he had any friends or allies.

She wants the army of the dead and Dany/Jon’s side to fight each other so she can go in and mop up the loser. In the meantime, she is going to reassert her control over the south.
And the snow falling on Kings Landing at the end showed the futility of her plan.

Ah yes, tower of joy was after the sack of KL. Thanks. So did the Kingsguard know Rhaegar was dead? Did Lyanna? Not sure we have that info, but most likely yes.
The Kingsguard knew. Ned and Arthur Dayne briefly discuss it. Lyanna doesn’t mention it, but given she swore Ned to secrecy, she must have known. No reason to pretend Jon is Ned’s son if Rhaegar won the war.

It just shows that the showrunners aren’t the geniuses, George RR Martin is. As soon as they didn’t have his books to go on for the details, the writing got sloppier.
Although frankly I hope Martin’s planning a totally different direction. I think that the seasons since the show was on its own have been great TV, but I don’t know how much I’d care about reading it. And as I said, if George RR Martin is just going to do a novelization of what we’ve seen, then he can just outsource that job to Alan Dean Foster or something.
At the end of it all it will be interesting to hear how much Martin had planned and how much the show runners made up. From the beginning Martin said he revealed the ending to them in case he chokes on a ham sandwich. He always knew how it would end. The journey got more complicated.

The rules of criminal and appellate procedure in the North are a bit . . . stark.

Bran sees a man being turned into a White Walker. Not that that Walker is the Night King.

And the snow falling on Kings Landing at the end showed the futility of her plan.
Look at it from her point of view. She has seen that fire can kill the wights. She has seen Dany’s dragons, the Unsullied, and the Dothraki. It’s reasonable to conclude that if a huge army and two dragons can’t defeat the undead, a huger army won’t make a difference. In other words, the likelihood of the Lannister forces being a deciding factor is small and she’s willing to take that risk for her own personal advantage.
She has good options no matter who wins the battle in the North. If Dany/Jon lose, she takes her army, sails with the Iron Fleet, and conquers some place in Essos. If Dany/Jon win, she attacks them as soon as the undead army is defeated. A war which she has a decent shot of winning.
Compare that with the case of her sending her army north. If Dany/Jon lose, she’s lost her army and the undead will kill her. If Dany/Jon win, the board is reset back to when she was losing badly. She loses the subsequent war and is executed.

The rules of criminal and appellate procedure in the North are a bit . . . stark.

Sure, if they can fly 200 mph, why not carry three times their body weight too?
Thank you for getting my joke and kindly clarifying the actual joke in case there’s anyone here not clever enough to get it on their own. Good looking out. You provide an excellent service to the message board. KUTGW.
I wonder if they took the undead corpse with them or if Qyburn was left with some samples. He seemed very fascinated with it. I sense some necromancy experiments brewing in King’s Landing next season.
I have to admit I was confused by the opening scene. The Unsullied and Dothraki armies show up at… that was King’s Landing then? At first I thought it was Highgarden, which I admit makes no sense. And it looked like a siege/battle was about to take place, which Jaime and Bronn seemed to acknowledge.
Then all of the sudden there is Bronn escorting their guests to the dragon pit. I felt like I had missed a couple of scenes. So were the Unsullied and Dothraki just the escorts for the royal party?

They were basically there to say “If anything happens to our queen, then the seige begins.”

Prove it to whom? Sansa herself is the only one who needs to be convinced.
One funny little bit was when Sam was talking to Brann and said to him, “Did you see that in one of your visions?” and by way of reply Brann just held up the Ravengram.
How the heck did Cersei and Euron plan their little drama in which Euron freaks out at the sight of a wight and pretends to leave for the Iron Islands?
