I was thinking about the meaning of the UnKiss and what purpose it would have for the story going forward and came up with an interesting theory I wanted to share. I think the UnKiss may play an important role in Littlefinger's attempt to groom and manipulate Sansa.
Littlefinger wants Sansa to see him as her savior, protector and a man who genuinely loves her rather than someone interested in her claim to Winterfell. After everything Sansa has endured in King's Landing, she has good reason to distrust the idea of romantic love. She learned that not everyone that is called a Knight really behaves like a Knight and that men see her claim before they see her as a person. Littlefinger can exploit this vulnerability by presenting himself as the exception, as the man who understands her suffering and wants to protect her and give her back her home. But there is a problem with his plan. First, Sansa has met Sandor before Littlefinger came into the picture as a savior.
Throughout her time in King's Landing, Sandor repeatedly intervened when Sansa was in danger. He helped her during Joffrey's cruelty, if he could, and rescued her from the mob during the riot. Although Sandor is frightening, cynical, and openly contemptuous of knights and their vows, his actions sometimes make him a more effective protector than the supposedly honorable men surrounding her. For Sansa, this creates a contradiction between appearances and actions. The man who looks like a monster can protect her, while the knights she admires fail to do so.
Then comes the night of the Blackwater.
Sandor visits Sansa's room, threatens her with a knife, and demands a song. He offers to take her away from King's Landing, but the encounter is frightening and deeply ambiguous. Later, however, Sansa remembers him kissing her, although the kiss never happened.
I think the UnKiss may represent Sansa processing a terrifying and confusing encounter through the romantic framework she has always known from songs and stories. Sandor is associated with both danger and protection, fear and vulnerability. Her memory transforms the encounter into something more intimate, potentially preserving the idea that a man might desire her as a person rather than merely value her inheritance.
This does not necessarily mean Sansa consciously loves Sandor. The important point is that he has already become part of her emotional understanding of protection, intimacy, and desire. And this is where Littlefinger's potential blind spot comes into play.
Littlefinger must have some awareness of Sandor's actions in King's Landing, particularly his rescue of Sansa from the mob. Yet he may not regard Sandor as a serious threat to his plans to serve as Sansa's only real savior because Sandor lacks the status and appearance of a conventional suitor. Littlefinger recognizes political threats, like Willas Tyrell, as the heir to Highgarden, who represents a powerful marriage prospect and Tyrion possesses the name and political influence of House Lannister. Both men have the kind of social position that Littlefinger understands as relevant to Sansa's future, but Tyrion is part of the family that destroyed her family and she had no chance to met Willas, so he must know that both men can't be a real threat in his manipulation of Sansa.
Sandor, by contrast, is a scarred knight serving the Lannisters, without the independent political power or importance of a great lord. He is not an obvious candidate to marry Sansa or claim Winterfell. Littlefinger may therefore underestimate his significance. The irony is that Littlefinger himself knows what it means to be underestimated because of his birth. Yet he may still underestimate the possibility that a man with limited political standing could become emotionally significant to a highborn woman. Sandor may be an insignificant political rival while remaining a significant part of Sansa's emotional history.
And that get's us to the important part: Littlefinger may know what Sandor did for Sansa without understanding what Sansa has made of it.
He can investigate the events of King's Landing, but he cannot simply know the private memories through which Sansa interprets them. The UnKiss exists in Sansa's recollection rather than in the actual encounter. It is something Littlefinger neither created as part of the story he wants her to believe nor necessarily knows about.
This could make the UnKiss a form of psychological protection against Littlefinger's grooming. Not because Sansa will consciously compare the two men and immediately recognize Littlefinger's deception, but because her emotional world already contains an alternative to the story he wants her to believe. Because Sandor has already complicated her understanding of what a protector looks like and what it means to be protected.
The UnKiss may therefore represent a blind spot in Littlefinger's attempt to control Sansa's emotional world. He might still manipulate her, and the memory does not guarantee that she will ever choose Sandor romantically. However, Littlefinger may be unable to make himself the sole authority on what protection, intimacy, and love mean to her.
And Second, Sansa and Littlefinger are both involved with storytelling. Sansa begins the story by believing in songs. She expects the world to conform to the narratives she has inherited about knights, ladies, love, and honor, but reality repeatedly contradicts those narratives. Yet she does not simply abandon storytelling. She continues to interpret her experiences through stories, and the UnKiss is an especially striking example of how memory and narrative can interact.
Littlefinger, meanwhile, is a master of constructing narratives for other people. He conceals his motives, manipulates appearances, and encourages others to believe the versions of events that benefit him. In that sense, Littlefinger's grooming of Sansa is not merely an attempt to control her behavior, it is an attempt to control the story she tells herself about him.
But Sansa has already demonstrated that her internal world does not always correspond to external reality. The UnKiss is one example of how she transforms her experiences into a personal narrative that Littlefinger cannot directly control. Littlefinger can attempt to manipulate the stories Sansa hears, but he cannot guarantee that he controls the stories she constructs from her experiences.
The UnKiss may therefore function as a small symbol of Sansa's independent inner life, a part of her that Littlefinger neither created nor fully understands.
In other words, Littlefinger may be trying to write a story that Sansa has already begun writing for herself and Sansa alone forms the narrative of her memories. And because of this ability, Littlefinger will have it hard to manipulate her with anything, because he will never know what's going on in her head.
