The opening scene of Game Of Thrones season 5 teases a pretty huge fan theory around Cersei's fate on the show.

Warning: spoilers ahead

Season 5 opens with a young Cersei, accompanied by an unnamed companion, seeking out a fortune teller.

While this mysterious prophet's name is not disclosed in the episode, fans of the book will recognise her as Maggy the Frog.

During the meeting, Cersei gets some rather cryptic responses from Maggy about the future. Here's how the scene plays out:

Cersei: I'm promised to the prince. When will we marry?

Maggy: Never. You will wed the king.

Cersei: But I will be queen?

Maggy: Oh yes. You will be queen, for a time... until there comes another, younger and more beautiful, to cast you down and take all that you hold dear.

Who is the prophet talking about?

Fans of the show will immediately associate this mysterious threat for Cersei, to Margaery Tyrell - who is all set to marry the current king Tommen and become Queen of the Seven Kingdoms.

The other candidate is of course Daenerys Targaryen, who seems quite determined to reclaim the throne.

Back in the show's opening scene, Cersei moves on from this disconcerting answer, and asks her second question:

"Will the king and I have children?" Maggy responds with: "The king will have twenty, you will have three." Cersei tries to interrupt, clearly confused.

Readers and viewers alike now understand that she did not conceive any of the former king Robert Baratheon's children; all of his children were bastards and all of hers were born from the incestuous relationship she has with her brother Jamie Lannister. (via Business Insider)

Maggy continues, stating "Gold will be their crowns, and gold their shrouds," before breaking into a hysterical laughter.

This statement clearly indicates that all of Cersei's children will die. With Joffrey already dead, it looks like Tommen and Myrcella will not be around for too long.

But what happens next is the interesting part. In the books, Cersei was granted three questions by Maggy. However, in the episode, the flashback scene suddenly cuts back (as Maggy is laughing) to present-day Cersei on her way to her father's funeral.

The book text has a third, and crucial line in Maggy's answer, reports Business Insider.

"And when your tears have drowned you, the valonqar shall wrap his hands about your pale white throat and choke the life from you."

Not only does the text make it clear that her children are going to die before her, but it also predicts her murder at the hands of "the valonqar."

Who/ What is the valonqar?

"In the High Valyrian language of the east, it means 'little brother'. Knowing that, all minds may jump to Tyrion, the youngest of the Lannister children," states the Business Insider report.

But, just as with Maggy's first prediction, there are alternate interpretations to this line.

Jaime, Cersei's twin, lover, and father of her children, was born just after her. He is technically another of her "little brothers."

Could he turn on Cersei in the future, and strangle her to death?

Makers of the show promised several flashbacks in season 5 and also hinted that they will divert a lot from the books. Seeing that the first flashback scene ended rather abruptly, it could be revisited at a later stage in the season where Cersei asks her third question and gets to know about "the valonqar" – maybe the scene will pop up as Jaime chokes Cersei to death!
