A Dance With Dragons:Right. My point being - there was no weirwood there, yet Bran could see what happened there. My initial understanding of his capabilities was that there needed to be a wierwood present for the 3 eyed raven to see stuff near the tree, and anything that didn't happen in proximity to a tree wasn't available for viewing. But this would be (another?) example that that's not the case - Bran can see anything anywhere that's happened in the past or is happening in the present. It would make him ridiculously powerful (like he said, he knows everything), in a narrative destabilizing kind of way - basically the same problem I had with the whole Hodor deal.
"Once you have mastered your gifts, you may look where you will and see what the trees have seen, be it yesterday or last year or a thousand ages past. Men live their lives trapped in an eternal present, between the mists of memory and the sea of shadow that is all we know of the days to come. Certain moths live their whole lives in a day, yet to them that little span of time must seem as long as years and decades do to us. An oak may live three hundred years, a redwood tree three thousand. A weirwood will live forever if left undisturbed. To them seasons pass in the flutter of a moth's wing, and past, present, and future are one. Nor will your sight be limited to your godswood. The singers carved eyes into their heart trees to awaken them, and those are the first eyes a new greenseer learns to use … but in time you will see well beyond the trees themselves."
