While it’s unclear who will be meeting in Season 7’s premiere episode, smart money says that it involves Euron Greyjoy.
And when the siblings departed their home with a fleet and headed to make an alliance with Dany, he vowed to kill his niece and nephew.
While he only made one appearance in Season 6, it was a powerful one.
Smart money says Euron will be the big villain of this season, and he and Cersei will likely wed to solidify and alliance and battle Cersei’s many enemies.
