WARNING: The following contains spoilers for the Season 8 premiere of Game of Thrones.

One of the most shocking revelations last season in Game of Thrones was Queen Cersei (Lena Headey) being pregnant. It seemed to be her final stroke to keep Jaime Lannister (Nikolaj Coster-Waldau) by her side, but still, it was something she clearly wanted kept secret.

In the Season 8 premiere, however, Cersei's suspicious actions in her latest meeting with the man she wants to deliver victory to her, the warlord Euron Greyjoy (Pilou Asbæk), left fans wondering if the situation has changed and if she's still pregnant after all.

In Season 7, when she met with Tyrion (Peter Dinklage) over a possible alliance with Jon Snow's Northern army, he noticed Cersei wasn't drinking any wine. That raised a red flag and, in their exchange, while she never confirmed it, Tyrion knew his sister was with child. Many also believed this was a big reason why she didn't want to seal any deals of war with Euron via sex, as she wouldn't want to desecrate yet another pregnancy for Jaime, whom she still considered the love of her life at that point in their tumultuous relationship.

But in the Season 8 premiere, "Winterfell," when Euron comes to Cersei's hall in King's Landing, their bond takes a drastic turn that indicates Cersei may not be pregnant anymore. Euron keeps trying to bed her, and after initial resistance Cersei surprisingly agrees. Later on, we see Qyburn tasking Bronn with killing her brothers -- an order straight from the queen -- so it's obvious Cersei no longer loves Jaime, and this tryst is a symbol of her emotionally and physically cutting ties with her sibling.

What also raises eyebrows is when Euron jokes about impregnating Cersei with a prince, she shoots a sly look before sipping on some wine. Taking this swig of alcohol is a defining moment, which suggests she isn't pregnant anymore. Speculation has been rampant online that Cersei lost the baby off-screen due to a miscarriage and needs to plan for another heir.

As such, with Jaime deserting, it makes sense to prepare for a future with Euron. This would allow her to pass the child off as a product of a union with Euron, and not of incest. Also, this act, apart from Cersei believing it's some twisted form of revenge on Jaime, will surely make Euron her puppet, so it's a win-win scenario for her.

Other theorists believe she may have terminated the pregnancy out of hatred for Jaime, especially because all the children she had with him ended up doomed. What's interesting about this is that a prophecy delivered to a young Cersei foretold she would lose her three kids once they were born -- Joffrey, Tommen and Myrcella -- so these conspiracy theorists think she was also avoiding such a fate for a fourth, while moving past Jaime.

Cersei has been a complex character throughout the series and, admittedly, you can't put it past her to fake a pregnancy to maintain a hold over Jaime for the war to come. But as Tyrion said, her not drinking wine meant it wasn't an act, so now we're really in the dark as to her status.

We're hoping to get more details straight from the horse's mouth as soon as possible, because for Cersei to go from rebuking Euron to sleeping with him seconds later, entertaining conversations about kids and also drinking wine means something is definitely up. Only time will tell, but as usual, this seems to be yet another secret Cersei's holding close to the chest.
