Rast-afari

The only semi logical reason I can think of (as a few others touched on) is that in order for the desired results to occur, Night King destroyed, Cersei dead, Dany killed, and Jon out of the picture, Bran has to say as little as possible.

I think the Night King was being a bit sadistic. He wanted Arya to know she was going to die and for her to think about it, similar to how he looked down at Theon after running him through. A typical super villain mistake.

Dany made all the Dothraki warriors her Bloodriders which means they are obligated to avenge their Khal.

Subjects usually are driven by the demands and whims of their ruler which in turn leads to advancements and innovations. If the King/Queen desires conquest then that will lead to military technology advancing (kind of how the Scorpions improved under Cersei). If the King/Queen wants the tallest, fanciest palace then architectural advancements will occur. A love of plays and music will lead to more competition and greater quality. The thing with Bran is he has no "wants" so there's nothing to push the people. He seems okay with keeping the status quo among the population which will result in stagnation. And if he's capable of living for a thousand years, well that's a thousand years of staying the same.

You either die a hero, or you live long enough to see yourself become the Mad Queen.

I don't feel any guilt for supporting Dany's journey just like I don't feel any guilt for cheering for a modern day action hero/heroine. I mean even movie Batman kills now. With the exception of razing Kings Landing, she, like them, always seemed to portray some sense of justice when doing the the killing.

After watching it again l noticed that after the Dothraki get decimated causing Dany to enter the battle, Jon does also, but attempts to go after the White Walkers who were on horseback in the rear. That's actually a good strategy which should have been discussed in their war council. Take out the generals and that will eliminate a chunk of Wights. Unfortunately the Night King summons a storm which forces Jon away.

The moment Jon's history is made public all hell breaks loose; "we chose a Targaryen to be king of the north?", "Ned Stark was a liar?", "my father died fighting for a lie?".

When Davos offered the Unsullied land in the Reach, Sansa did not look happy.

Do we? I would think the Lord of Light would prefer Dany than Bran.

Who would you want to captain the Enterprise; Spock or Kirk? Data or Picard?

The fact that Grey Worm kept Jon as prisoner and didn't execute him automatically is what bothered me. Why negotiate? Unsullied don't get intimidated by being out numbered. They manned the front line against the Night King's forces while the Northern armies were running in retreat. And I'm not sure if they were out numbered. Assuming everyone lost 50% of their troops as stated in episode 4 that still leaves the Unsullied and Dothraki with more than the North. 2) Letting Jon come back after agreeing to banish him in front of all the representing powers would mean Bran's word isn't worth jack.

I think that was the Lord of Light's intention, misdirection kind of. NK threw a wall of Wights plus Viseryon at Jon. He was so confident when he approached Bran you could almost hear him monologging in his head. Also, where did the ice spear that he threw at Drogon come from? (okay, I watched it again and he has a spear when he's riding Viseryon)

All those Ironborn who accompanied Theon might as well have red shirts on. Dead.
