Bran Was In Control The Whole Time
There was a conversation I just read on the Blind Wave finale video that is so true to what the actual outcome was for this show. The conversation goes as such....
Someone said while the rest of the people were playing with their toys on the ground, Bran was playing 7 dimensional chess. He set all of this stuff up to happen with driving Dany crazy, revealing Jon's parentage, and allowing Kings Landing to burn so he could become King.
Everything that happened was of his doing. Even the beheading of Ned to Robb's murder, to having Sansa as his tool to the North. She thinks she's free there, she's not.
Also don't forget what Max Von Sydow's character said. He was 1000 years old. Bran has been "elected" King. He can never have children, but he'll rule for 1000 years because he can't die. And why else would he have mentioned Sansa on her wedding night...... Why bother mentioning this to her? Why?
He's not the saviour. He's Damien Thorn personified. He made Dany go mad. Therefore HE murdered thousands in Kings Landing, not Dany. That scene when the bells rang, that was Bran warging her into destruct mode.
I believe that Bran can't warg a dragon because what Dany said about a dragon is not a slave. But he can warg into the direwolves.
And it's even worse. According to the ASOIAF lore, Missandei's home is Naath. What's in Naath? Poisoned butterflies. The Dothraki and the Unsullied are being sent there by Bran to have them die. They won't come back. He's even sicker than we think. Just like when he commented on Sansa's wedding night. Why would he have done that? Did he do that to gauge her response because clearly he got a rise out of her. Playing games maybe?
