Love reading different GOT theories. Lately you can definitely let your imaginations run wild with the implications that Bran has some powers we do not yet fully understand. I've read some interesting thoughts that he is kinda the cause of all the things happening in westeros, even his own demise of being pushed out the window. "burn them all" specifically being linked to the whitewalkers is something I have not yet considered.. thanks for stiring that up for me.
