Game Of Thrones Season 7: 11 Major Plot Hints From The New Trailer
4. Euron And Cersei Form An Alliance
The Battle of the Geyjoys isn't the only slice of Euron madness we get in this trailer, as the show ramps up its efforts to make him a convincing villain.
How do they do that? By allying him with the other major villain (not called the Night King), of course. It looks like he completed the building of his Iron Fleet, and now that fleet is sailing into Blackwater Bay for a meeting with the new Queen.
A Euron/Cersei alliance has made sense since they both took their respective thrones: Euron needs a serious power base in Westeros, Cersei needs soldiers, and a marriage can make any house stronger, especially when it's between two great houses such as these two.
That is assuming there is a marriage proposal, but even if not there's going to be some sort of allegiance cooked up. They're both absolutely mad, and both now gunning for Daenerys Targaryen. We saw Cersei greeting someone in the previous trailer, which is probably Euron, and there's this spoiler, which the Crow's Eye is probably responsible for.
