Game Of Thrones Season 6: 15 Major Plot Hints From Trailer 2

3. Northmen And Wildlings Vs The Boltons

We've been teased a big battle for a while now, but this trailer gave us the best look yet at who is involved. 

We've already seen Ramsay Bolton at the head of the army, so it was safe to assume they were one part of it, but that's shown to even greater effect here with the haunting shot outside of Winterfell, showing a number of burning flayed men. It's the sort of imagery that would make you think twice if you're heading to oppose them. 

For the other side, the presence of Tormund Giantsbane confirms the wildlings involvement (it also looks like a giant in the background of another shot, so it could just be the perspective), but we also see banners of Houses Stark, Mormont, and Hornwood lined up to oppose the Boltons, making this army a major Northmen/Wildling alliance. 

Also seen, although in a different shot, is the sigil of House Umber. They've not been seen for a number of years now, but Smalljon Umber has been cast for this year, and their presence in this trailer confirms that they'll also have a part to play in this battle. They were previously loyal to House Stark, but it's not obvious whether or not that's still the case.
