True, but he’s not even the dumbest of the folks who grew up at Winterfell: Rickon is the one who never thought to serpentine while running away from a guy shooting arrows at him. None of the Starks are that bright, eh?
Well, one of them does learn. 
Jon aggravates me because he gets rewarded for being stupid. He is even worse than Arya in that respect.
Lone wolfs aren’t bright. It’s the pack that is bright; it’s the pack that survives. The Starks only work when they’re a unit working in tandem, as seen in the Littlefinger trial, each complements the other, like wolves circling around prey, each draws from the others’ unique strength. On their own, they’re all weak. Arya failed at being a Faceless Man and only luck allowed for her survival. Sansa would be dead if not for Littlefinger, Theon, Brienne, and others. Put them together, though, and they’re pretty unstoppable. Arya is the assassin; Sansa is the politician; Jon is the knight. They are wolves, wardens of a cold and dreary realm, and that they excel at being.
It’s not really clear (some might even say it’s inconsistent) how wights are made. This episode suggests a White Walker must raise them, and the wight is “alive” only while the White Walker is. The dead don’t automatically rise just by nature of being north of the Wall.
This brings up the question of how the dead Night’s Watch members animated in Commander Mormont’s quarters in Season 1. It has been fanwanked that a WW turned them into wights, then left them dormant to “play dead” until they were in Castle Black.
They really need to bring that out on the show, because individually they all kinds of stupid. Jon especially.
And why was this wight acting like an assassin and not a rampaging zombie? It showed more intelligence than its brethren that we come to now later. Was it maybe remote controlled by a White Walker? How if the Wall stops their magic? Or was it more intelligent because it was still well preserved? Was it there explicitly to assassinate the Lord Commander? What if it had succeeded? Would Mormont have turned? Would the Watch have gone beyond the Wall in strenght without him? So many questions.
Whether they were turned into wights before or after passing the Wall, it would seem to call in question the Wall’s magical ability to keep out wights or White Walker magic. (Not that this matters now that the Wall has been breached.)
White Walkers have been wandering around not too far north of the Wall since the first episode of the first season. What were they doing?
In the first episode they dismember the wildlings they’ve killed in order to make funny patterns in the snow instead of making them into wights. Why?
It’s pretty hard to account for the wanderings of the Army of the Dead. In season 3, it attacked the Night’s Watch at the Fist of the First Men. At the end of season 5, they attacked Hardhome, which is half the continent away and farther north. But perhaps these were two different armies.
The Night King also seems to be all over the place. In season 2 he apparently is not too far from Craster’s Keep, since he is present when one of his sons is turned. In season 5 he is at Hardhome, much farther north. In season 6 he is at the cave of the Three-eyed Raven, which seems to be even farther north. So neither the Army of the Dead nor the Night King seem to have been moving consistently south.
Maybe they were just wandering around killing time until someone was dumb enough to send them a dragon. 
I initially meant that jokingly, but perhaps it actually works if the Night King has some precognitive ability. Which could also explain things like “Why did they just happen to have some giant chains with them?” It sure would be nice if the show offered that sort of explanation, though. Instead they seem to be trying to see just how far they can stretch the Rule of Cool.
"NOW this is the law of the jungle, as old and as true as the sky,
And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree trunk, the law runneth forward and back;
For the strength of the pack is the wolf, and the strength of the wolf is the pack."
You forgot Bran who is probably the most powerful of the lot, overpowered IMO, though they manage this by making it fairly arbitrary as to when and how he intervenes.
What happened to Craster’s sons? With all those girls around you have to know there are also a lot of bouncing blue eyed baby boy wights hanging around somewhere?
They showed the Night King turning them into wights right then and there while they’re little, they’re not keeping them on a human baby farm until they grow up. What are they going to do with them? Since they’re now undead they’re not going to grow at all, right?
And you know they can’t keep up with the rest of the undead army with those short chubby legs no matter how slow the army’s moving.
I thought the Night King was turning Craster’s baby boys into White Walker babies, and somehow, somewhere, they grew up to be adult White Walkers.
Apparently living humans can be turned into White Walkers, and dead ones get turned into wights.
Craster’s last son would be about four years old now. I wondered about just how fast White Walkers grow up.
Its fall also points to a lack of sufficient resistance against White Walker magic (unless we consider the dragon an aberration). I’d still like to know plan A.
Though this all might indeed be preordained and everything that happens has already happened; and they all just go through the motions. Puppets on a string. And some of them know it.
Yeah. “Always the artists.” Do they just mimic symbols used by the Children without any understanding beyond a “racial” memory? Is it ritualistic behaviour? Has it religious meaning? Or do the White Walkers at least understand their application?
I still thinks it’s odd that of all the creatures in this world the Children *of the Forest *supposedly developed the [del]technology[/del] magic to create something so alien to them as the White Walkers.
The image of a White Walker kindergarden has always been hilarious and creepy.
