Game Of Thrones: 12 Things You Learn Rewatching Season 6
8. Bran's Visions
Sticking with Bran, and the new Three-Eyed Raven has a number of visions in the episode following Hodor's death, Blood of my Blood.
We get to see the caches of wildfire kept under King's Landing, and eventually a glimpse of an actual wildfire explosion. That's what Jaime killed the Mad King to prevent - another part of these visions - but it's also exactly what we see in the Season 6 finale.
There's also a couple more shots of the Tower of Joy, including Ned's bloody hand over an even more blood-soaked Lyanna, giving us another hint at Jon's parentage before the big reveal. There are also lots of shots relating to the undead and the great war to come, hinting at the important role Bran and Jon have to play.
Then there are the shots of Daenerys' dragons, including Drogon's shadow as he flies over King's Landing (as seen in Season 4 as well). That's something we still haven't seen, so should we expect a dragon attack on the capital in Season 8? It seems pretty likely as things stand.
