It wasn't too long ago whenGame of Thrones aired its season finale, but fans still can’t stop talking about some of the major characters. Theories have it that Cersei Lannister’s (Lena Headey) pregnancy is not something that her twin brother Jamie (Nikolaj Coster-Waldau) should be responsible for. Apparently, everyone is skeptical about the pregnancy and suggests that the baby’s pop could be Euron Greyjoy (Pilou Asbaek). Given the fuzzy timeline that the show gives, it’s definitely possible that the Kingslayer is not the unborn child’s father. Recently, Coster-Waldau gives another teaser on whether or not his character is the baby’s dad.

Who is the unborn baby’s father?

InStyle recently sat down with Coster-Waldau [VIDEO] to discuss some fan-made theories and speculations about Cersei’s pregnancy and if Jamie will be the one to kill his twin sister/lover.

The “Game of Thrones” star hinted that he’s no longer sure if the Kingslayer is actually the father of the baby. “That’s what I thought. I mean, I still think she is. But I don’t know how. I’m not sure anymore,” he said. “It might be that she was just playing all of us. When we did it, I definitely believed her. And that, I guess, is what’s important. Jaime believed her.”

Euron Greyjoy might be the one

During the “Game of Thrones” Season 7 finale when Cersei told Jamie that she lied to Jon Snow (Kit Harington) and Daenerys Targaryen (Emilia Clarke) that she is sending the Lannister forces north. Jon and Dany tried to convince her to fight with them against the White Walkers. However, it turned out that it was just for show and told the Kingslayer instead that Euron is sailing to Essos to get more forces.

Unfortunately, they are not for the so-called Long Night war, but are to help defend King’s Landing from the wrath of the undead army.

Apparently, Jamie was surprised about the news that Cersei and Euron both planned something without him. That said, it means that the queen has been seeing the Greyjoy guy behind the Kingslayer’s back. Who knows, they’ve probably done something that “Game of Thrones” chose not to divulge for now. Theon’s (Alfie Allen) uncle has proposed marriage to the queen and the chance of marrying her would be huge if he follows what Cersei wants.

Will Jamie kill Cersei?

Coster-Waldau also told InStyle that it’s possible that Jamie would kill Cersei, given the “valonqar” or “little brother” prophecy from Maggy the frog had told his twin sister before. The Mad Queen was told before when she was a kid that she would be killed by her little brother. Jamie is his twin who came out after her, but it’s also possible that it’s going to be Tyrion (Peter Dinklage) who will do the “honor.” What do you reckon, “Game of Thrones” fans?
