It’s no doubt that both Arya Stark and Cersei Lannister are two of the most powerful women in the whole of Westoros.
Cersei Lannister, the one who presently sits on the iron throne. Probably the most hated woman in all of the seven kingdoms surrounded by enemies. Arya Stark on the other hand is the second daughter of late Ned Stark a girl who has gone through it all throughout the progress of the seven seasons and probably the best female swords(woman)man in Westoros.
In the first episode of season seven when Arya Stark came across some lannister soldiers in the woods, she told them that shew was on her way to kings landing to kill the queen cersei, although this elicited laughter frim the soldiers, Ed Sheeran himself and was considered as a joke but it actually had some degree of truth underneath it.
To be frank, there’s probably no one else more deserving to kill cersei than Arya stark. You might want to mention Bran but with being the three eyed raven now I doubt if killing Cersei will be of great interest to Bran, then we have Sansa Stark, shes probably the only Stark member to have gone through hell as much as she did at the hands of Cersei but we all know Sansa is more of a lady than a killer as displayed in the season finale of the the seventh where she ordered Lord Baelish to be killed for his many treason act.
So with all this act crosses out, we’re left with none other than Arya Stark but the truth is Arya Stark Cannot Kill Cersei Lannister and here’s why, do you remember the prophecy Cersei referred us back to in season five? After she realized that her daughter Mrycella has been killed, where she want to meet Maggy a witch who gave her a prophecy about her future?
Cersei mentions the prophecy of a witch she’d been told years ago: “She promised me three children . . . she promised me they’d die,” she says, and of course, it wasn’t all that long ago that we actually saw this scene on the show; it happens in the season five premiere. Here’s the clip where a young Cersei visits Maggy the frog, the fortune teller in question.
“Everything she said came true . . .” Cersei says in the season seven premiere to Jaime, her beloved brother and father of her three children — all three of whom are now indeed dead. “This prophecy, it’s fate.” So let’s go over exactly what the witch did prophecize and how it all plays out on the show.
1. “You’ll never wed the prince, you’ll wed the king.”
Did it come true? Yes. Cersei marries King Robert Baratheon and not “the prince” — Rhaegar Targaryen.
2. “You’ll be queen, for a time. Then comes another, younger, more beautiful, to cast you down and take all you hold dear.”
Did it come true? Yes, though the younger, more beautiful queen had been questioned. Margaery came to mind first as the young queen who was married to King Tommen, but now that she’s dead, it’s assuredly Daenerys Targaryen, the queen we are all hoping brings about the end of the Lannisters.
3. “The king will have 20 children and you will have three. Gold will be their crowns . . . gold their shrouds.”
Did it come true? Yes. The king did have multiple illegitimate children without the help of Cersei, while Cersei bears just three: Joffrey, Myrcella, and Tommen — all three of whom have died. Joffrey and Myrcella are both poisoned, by Lady Olenna Tyrell and Ellaria Sand, respectively. Tommen tragically commits suicide by throwing himself out a window after he sees that Cersei has murdered his love, Margaery Tyrell. Now that Cersei is pregnant, a fourth child would contradict the prophecy, which has a lot of people believing that she will either die before her child is born, miscarry, or that she’s not even pregnant at all.
But wait, there is one more piece to the prophecy in George R.R. Martin’s books that did not make it into that scene in the show. The witch also tells Cersei: “And when your tears have drowned you, the Valonqar shall wrap his hands about your pale white throat and choke the life from you.” “Valonqar” means “little brother” in Valyrian — and if we are taking that literally, that means Tyrion . . . or Jaime, who is her twin but could technically be her “little brother.”
So that’s why no matter how much Arya wants to or tries to, she wouldn’t be the one to kill Cersei Lannister.
