Game Of Thrones Season 8: 11 Characters Who Could Kill Cersei Lannister
4. Arya Stark
Along with the Hound, Arya Stark is off to King's Landing to take care of some unfinished business. Given that her kill list only has two names left, and both of them reside in the capital, it's safe to surmise that said business involves killing one of the Mountain and Cersei.
If we assume that the Hound is taking care of the Mountain, then that leaves Cersei in the capable hands of Arya Stark. She's already killed a Queen, so why not a King as well? Melisandre referenced her "brown eyes, blue eyes, green eyes" quote in The Long Night, with the order changed to emphasise the blue eyes of the Night King. But the green eyes have yet to be killed, and if they're retconning that line anyway, perhaps they'll go further and have it mean she'll kill Cersei as well.
Arya is one of the few people who might well be able to get into a well-protected King's Landing, thanks to her Faceless Man training. She seemingly still wants to kill Cersei. And the show has already had her knock-off one major villain, so they could give her the sweep. At the same time, that could be one of the things that counts against her: she's already killed the Night King, will they then have her kill Cersei too?
