@Arkandel ***=Theon... Ugh. Theon...***
So, for some reason some people actually like him and saw his end as a redemption story, but I was not one of those. And I'm firmly convinced (based on nothing but my own starry desires) that Bran did not believe a word he told Theon. Theon was not a good man. Bran told Theon what Theon needed to hear to get him to charge the Night King. Bran knew he'd die (that wasn't a surprise to anyone), but he also knew that without the proper motivation (manipulation) Theon would 'pull a Theon' and just stand around frozen with fear. Because Bran, with his mystical time sight, knew that Bran would survive due to the fact that the Night King was gonna be dead within moments. So Bran needed Theon to hurry and go get himself killed before Arya attacked so that he would die. Cause he deserved it.
Yeah. That's what happened.
