An old prophecy revealed the death of Cersei Lannister at the hands of the Valonqar, which in Valyrian means “Little Brother.” This prediction could point at her twin Jaime, who was born a few minutes after her, or at her younger brother Tyrion. The common speculation is that Jamie fulfills this prophecy in Season 8, although the events in the Season 7 finale of “Game of Thrones” point to a different person.
Cersei’s death
A flashback in Season 5 revealed the young Cersei asked about her future from Maggy the Frog. The woman told her that she would marry a king, be a queen and have three children. This came true when Cersei married Robert Baratheon, had three children out of incest and became Queen of the Seven Kingdoms. The prophecy also said that she would die at the hands of the Valonqar. These were her words, “the Valonqar shall wrap his hands about your pale white throat and choke the life from you.”
Season 7 hints at Jaime as the Valonqar
A scene in the premiere of Season 7 showed Jaime and Cersei at the map room talking about war strategies.
Their positions as they stood on areas of the large map on the floor hinted at Jaime being the Valonqar in the prophecy. In George R.R. Martin’s book, the area where Cersei stood is called “The Neck” while Jaime stood at the region called “The Finger.” Their positions are rather cryptic of Cersei’s death by choking.
An assassin kills Cersei?
However, another theory suggests that Jaime would not be responsible for his sister’s death. Instead, one person who always had a vendetta against the queen is likely going to kill her -- Arya Stark. We all know that she has a kill list, which literally is a list of names she vowed to kill. Cersei is still on the list and it is likely that in “Game of Thrones” Season 8, she will continue her mission to kill her.
How Arya kills Cersei
Littlefinger’s death in the Season 7 finale makes it easier for Arya to gain safe entry to Kings Landing. She can borrow his face and get inside without alerting suspicion. She can even get close to Cersei or Jaime. This is where the theory that she kills Cersei comes in although she would have to sacrifice the Kingslayer first. Then she can assume Jaime’s identity and kill Cersei. Arya not only crosses out Cersei’s name on her list but she also fulfills Maggy the Frog’s prophecy.
However, actor Nikolaj Coster-Waldau believes that Jaime will fulfill the prophecy. He told InStyle that it would “make sense” and that there would be a “beautiful connection” if Jaime kills his sister. “He killed the Mad King and now he’s killing the Mad Queen,” he said.
