Game Of Thrones Season 7: 10 Huge Questions After The New Trailer

This could also be titled: "How will Bran completely mess everything up this time?"

Last season, his visions lead to the deaths of the Three-Eyed Raven, Hodor, Summer, and the Children of the Forest and being branded by the Night King. That's a lot of ways to screw up in a very short time period.

Bran may not have appeared in the new trailer many times, but the implications behind his appearances are huge.

Bran appears to have warged into a flock of ravens, and the very next shot is of the Night King looking upwards suspiciously. While this could just be a case of tricky editing, it certainly appears as though the Night King is able to detect Bran's power even when his physical body isn't around. Which of course provides a gigantic problem.

If the Night King was able to break through the magic protecting the Three-Eyed-Raven's cave, is he (it?) now able to also break through the magic of the Wall? What is the real extent of the Night King's powers? It has long been theorized that Season 7 will end with the Night King bringing down the wall and laying siege to Westeros. Is Bran the key to that plan?

Will Bran return to Winterfell, as has been suggested by the above picture? Jon Snow has to find out about who his real parents are at some point.

And most importantly of all: what other fan theories can Bran's confirm or refute?
