I've posted about this recently but I just wanted to pull some evidence and theories together to tie this up now the season is over.

This is the question: Does the Night King have green sight? Did he plan all of this all along?

Some things have been weighing on my mind recently that other people (as far as I know, correct me if I'm wrong and I'll cite) haven't been talking about.

First the stuff we all know:

• Beyond the wall, there was 1 Wight left standing when Jon kills the White Walker, oddly convenient.
• The Night King had exactly 3 ice spears ready to kill the dragon.
• They had dragon-sized chains ready to go.
• The Night King likes to leave 1 person alive to go and tell the story. You could call that just taunting, but it's possible that the people that are left alive tell just the right person in just the right way to set some important events in motion.

So that's the stuff people have been talking about. On it's own this doesn't really prove anything. Reddit user /u/UWFdude made a great post explaining what the Night King was thinking during the Beyond the Wall scenes and how all of that happened Here

But there's more, some other things that we've been overlooking that don't seem to make much sense if the Night King has no knowledge of future events.

• The Night King needed that dragon to get past the wall. If he hadn't baited the dragon, or had no plan in place to get one, how the hell was he going to march south?
• Don't forget that the Night King and the White Walkers were sleeping for thousands of years, and happened to wake just before the dragons were born, not after, so we can't say that the dragons awoke them along with the red comet and all the magic in Westeros, they woke up in S1E01.

I refuse to believe that the Night King waking up and beginning his army at this time is a coincidence. He had to know something that made it the right time to start his march south, and the only thing of real importance that happened is the birth of the dragons, which he later captured and used to bring down the wall.

Now is the Night King totally omnipotent and knows the future in great detail? Probably not, he's f***ed up too many times. Missing Drogon, letting the party get away with the Wight even though he tried to destroy it, quite a few White Walkers dying off.

So he must have glimpses, just like Brann. Perhaps the future isn't set in stone and only certain events are certain given a certain course of action, the rest being up in the air.

I don't know, what do you all think? There's got to be a bit more to the Night King than meets the eye, but he's certainly not all-powerful, there's hope.
