In the aftermath of her conquering of King's Landing it's clear she has no intention of stopping her world domination. She sees her acts as liberation and wants to continue on that path from "Winterfell to Dorne," an invocation that gets some side-eye from Jon and Tyrion. But Jon continues to defend her, even after she imprisons Tyrion. The Lannister implores him to reconsider. He clearly does. He walks to the throne room, where she's confident and gloating, and asks her to lead with forgiveness. She rejects that notion, but she still wants him with her. "We do it together," she says. "We break the wheel together." They kiss, but in their embrace he stabs her in the heart.
The conflict between Jon and Daenerys has defined the show's final season. Jon learns he's a Targeryen in the premiere, and wrestles with this information paired for his professed love for Dany in almost every episode. Even as Sansa and Arya Stark caution him against unwavering fealty, he forges ahead. His only betrayal is telling his sort-of siblings the true nature of his parentage, which nonetheless sets off a chain of events that results in the death of Varys, and, indirectly, her rage spiral that leads to the destruction of King's Landing.
As we watched these final moments unfold, it felt like we were getting an abridged version of the story. Because of the shortened, six-episode run, the showrunners had to escalate the conflict between Daenerys and Jon quickly, allowing for little nuance in the process. Daenerys became desperate not just for power, but for Jon's affections. When he physically rejects her kiss in "The Bells" -- he's more uncomfortable with the whole aunt-nephew thing than she is -- she decides to rule with fear. Before she sacks King's Landing, she's consumed by grief in part due to the beheading of her her friend and confidante, Missandei, and in part thanks to Jon's dismissal of her advances.
Ultimately, Jon's cooler head prevailed, even at great personal cost. Now her death reframes their relationship -- and, frankly, the entire series -- with some icky gender politics. Daenerys becomes a woman too irrational to hold power, whereas Jon turns into the man destined to stop her before she burns the world.
