[EVERYTHING] My theory about Bran / Hordor, making sense of the episode "The Door"

It doesn’t make sense to me that the Three Eyed Raven would keep Bran warged into the Weirdwood tree while it’s literally raining zombies. Why warg through Hodor from the past to help out, when he was sitting right there next to all of them in the present? Seems like a very unnecessary move just to “close a time loop.” There has to be a cause for that move to begin with. It’s my hypothesis that the Three Eyed Raven wanted Bran’s consciousness to be stuck in the Weirwood tree realm until his body is brought to another tree. This is the only reason I can think of for why they would sacrifice Hodor’s entire life since adolescence. Why he wants Bran’s mind in the Weirwood, I’m not sure, but possibly because there are integral things he needs to learn within the immediate future. I know there are some hole’s in this, like the TER advising bran not to warg alone, or not stay in the Weirwood tree for too long, but it seems like it could be a desperate times call for desperate measures situation.

TLDR: The Three Eyed Raven was forced to have Bran’s mind stuck in the Weirwood network for the time being, and was willing to sacrifice Hodor’s sanity to see this through.
