As of now, there is perhaps none other more satisfied with his life than the usurper of the Ironborn, Euron Greyjoy (Pilou Asbæk), who finally got to sleep with Cersei Lannister (Lena Headey) after bringing the Golden Company to her doorstep.
However, now that the hurly-burly of the Great War is done, and the battle is won, Euron is still standing by Cersei perhaps in the hopes of winning her over which will be the easiest way for him to get to the Iron Throne. On the other hand, Euron has already established himself as one of the biggest villains on the show - immediately after Joffrey (Jack Gleeson) and Ramsay Bolton (Iwan Rheon).
So what lies ahead for this Ironborn who has time and again proved himself to be an irredeemable traitor? Asbæk said in an interview he wanted to be a villain unlike Joffrey and Ramsay, who can be best categorized for their inhuman treatment of other humans. "I'm walking in the footsteps of some very, very evil people. I wanted to do something else with [showrunners] Dan [Weiss] and David [Benioff] and what they wanted. We wanted to do a more seductive, more charming choice. A little more like… You wouldn’t know if he’s going to kiss you or kill you, you know?"
Euron, unlike Joffrey or Ramsay, is not a man who kills people for the pleasure of it. Instead, he always has some agenda behind killing other characters. Like many, he is someone who wants the throne, and this is the only reason why he chose to stand beside Cersei.
He visits her after receiving a formal invitation where Cersei offers to help him become the real ruler of the Ironborns if he in his turn helps her defeat Daenerys Targaryen. Euron immediately asks for her hand in marriage, and thus the negotiation between them begins.
Euron keeps his side of the negotiation by proving his worth to Cersei when he brings in the Golden Company. Cersei, who for so long had managed to keep Euron at bay, finally gave in and let him sleep with her.
Euron promised her he would make her give birth to his children. Even if Euron manages to do so, there are quite a lot of things at stake for him. First, he has left the Iron Islands unguarded which means Yara Greyjoy can now easily reclaim the throne, and turn the Ironborn against him.
On the other hand, Cersei - even if she wins - will never really let Euron marry her. She will, in fact, kill him and take over the rest of his remaining men. Hence, the upcoming episodes are quite important when it comes to Euron as he might meet just the same fate as his nephew, Theon, but sans the honor and redemption.
