Hey Keith, I get what you are saying, my point was that Bran cannot literally go back in time physically and interact with folks in the past (I included a BUNCH of textual references over the five articles I wrote on this subject).

The whole reason I wrote the posts wasn’t to suggest he can’t influence the past (and the future through the past) it was that he can’t do it in the way that would be necessary for the Bran = Night King theory to work.

I have written about time and time paradox many times before as well, I was writing about a particular theory and a particular set of propositions.

Thanks for the very detailed response :)
