Why 'Game of Thrones' fans should worry about Cersei killing Jaime in season 8 instead of the other way round
Cersei deems Jaime's love for her more on a level of devotion than anything; which also means that she can forgive anything Jaime does as long as he doesn't fall in love with someone else
Spoiler alert for season 8 episode 4
Ever since it was announced that the ongoing season 8 will be the final season of 'Game of Thrones', with everything that had transpired over the years, fans had grown certain that it will be Cersei Lannister's own twin brother and lover, Jaime Lannister, who would be the one to kill her in the end. The arc seemed not only righteous but poetic too and soon fan theories about Arya Stark (Maisie Williams) — the faceless assassin — killing Jaime to take on his face and kill Cersei started swarming in too. That is until the latest episode aired and we saw Jaime do something we never would have expected him to do — something that makes us feel that, contrary to fans' popular beliefs, it might be Cersei who ends up killing Jaime this season.
Over the years we have had Lena Headey shock, scare, and surprise us with her character Cersei's ruthless politics and affinity for brutal vengeance. The only time we have ever seen Cersei soften up is when her now dead children were in question, or when the topic involved her brother, and lover, Jaime (Nikolaj Coster-Waldau). Cersei and Jaime's love for each other runs so deep that they have had sex next to their dead son's body, and Jaime had even pushed an innocent child off a tower, crippling him for life, just for Cersei. So it's quite natural that Cersei deems his love for her more on a level of devotion than anything; which also means that she can overlook anything Jaime does as long as he doesn't fall in love with someone else.
Cersei's inherent cruel nature has made it obvious that she can forgive Jaime for everything except loving someone else — something that fans believe Jaime has been indulging in over the recent past, with a certain Ser Brienne of Tarth (Gwendoline Christie). That Jaime and Brienne's relationship is too pure for the world is no secret. They are friends who respect each other first and newly-turned lovers later. But taking all of that into account — both with Brienne vouching for Jaime's life in the North, and him knighting her on what was expected to be their last night on the planet — it's not that far fetched an idea that maybe Jaime has in fact fallen for another blonde, who is nothing like his sister.
What's bigger? Jaime had sex with Brienne voluntarily after learning that she was a virgin, and no, that wasn't an act of owning something within her. If anything, Jaime did it out of deep love and admiration, and at that moment, it looked more like Jaime was finally having sex with the girl of his dreams, than Brienne scoring the one man she has been in love with. To seasoned fans, it might almost appear as if Jaime has finally broken out of Cersei's spell and sought someone who he could end up having a sane life with in the future. And that is exactly what makes us so scared of the man's fate in Cersei's hands, especially now that he's returning back to her in King's Landing.
In the fourth episode, we saw Tyrion Lannister (Peter Dinklage) — Cersei and Jaime's dwarf brother and the hand of Daenerys (Emilia Clarke) — try to reason with her to give up violence and surrender, if not for anything else, for her unborn child on the way. Tyrion told Cersei that she is not a monster, as she has loved her children more than anything on the planet. And all of those children were Cersei and Jaime's — just like the unborn child growing in her currently.
We have seen what insecurity and jealousy can make Cersei do since she burned down an entire city in an attempt to kill Margaery Tyrell (Natalie Dormer) — who she thought was the prophecied younger and more beautiful queen that would dethrone her eventually. So to learn that Jaime has been with another woman whom he might possibly be in love with, would have catastrophic effects on the Mad Queen's mind. The only way she would deem it accurate to avenge this betrayal in her eyes would be to kill Jaime, and we all know the vile and vain queen is beyond capable of doing that. To Cersei, this simple act of affection on Jaime's part might seem like him having turned against their unborn child — and seeing his loyalty fleeting in this manner, there's no way she would let Jaime get out alive.
