The Battle of Winterfell may be over but there is another huge war on the horizon, as all eyes turned to Cersei Lannister. The Night King has been defeated and those still living have looked south and how to remove Cersei from Westeros and claim the Iron Throne. It is believed a huge clue in the trailer for episode four of season eight has shown who kills off Cersei in Kings Landing.
Daenerys Targaryen, the Mother of Dragons, is very much gunning for Cersei, especially after she doubled crossed Dany with her promise to help at the Battle of Winterfell. In the trailer, Daenerys says that Cersei needs to be "ripped out of Westeros" and has predicted 'The Last War' will be the moment that that Iron Throne is claimed. There are a number of characters that could be the one that lands the fatal blow on Cersei, from her brothers Jaime and Tyrion to Arya Stark.
It has long been known that Cersei is one of the four people left on Arya's 'kill list' and that these will be removed before the end of the final episode. Jaime and Tyrion meanwhile are now fighting against their sister and despite her carrying Jaime's child, he wouldn't hesitate in ending her evil reign. It is a remark by Melisandre, the Red Woman, though that seems to have given the biggest insight into who will be the one to kill off Cersei.
In the clip, she notes that Arya will kill those with "blue eyes", which would fit in with her destroying the Night King with her Valyrian steel dagger. She then says that Arya would also kill those with "green eyes", which points towards her fulfilling her wish to bump off Cersei. While Daenerys and Jon Snow head towards claiming the Iron Throne, it would seem that Arya will have a huge say on whether Cersei can keep her hands on it.
