Game Of Thrones Season 7 Finale: 10 Hints From The Trailer
9. The Greyjoys Defend King's Landing
As Dany's ships head into King's Landing across Blackwater Bay, they are greeted with the formidable sight of Euron Greyjoy's fleet, stationed in the waters just off the Red Keep and clearly designed as an intimidating welcoming party.
Presumably, this comes after they've left their post at Casterly Rock (because the Unsullied managed to creep out of the back door) and is Cersei's idea of scaring her visitors out of doing anything silly.
It's all very daunting. So daunting in fact that Varys has changed out of his gold-tinged robes and into something more sombre, for some reason. He's ready for sh*t to go down. It's quite shocking to see how calm Theon is here too.
It looks as if Euron is sitting in wait. It could be no more than a show of power (particularly as we know they all get through it), so maybe don't expect another big sea battle. Not yet anyway.
