Lara Jean Covey and Kitty Song’s relationship

Lara Jean Covey and Kitty Song’s relationship combines easy intimacy with the ache of growing up and leaving home. Lara Jean acts as Kitty’s affectionate older sister and, when Kitty’s sharpness wounds Margot, as a mediator who explains how family changes can make someone feel displaced. Yet on the night before college, Lara Jean chooses a private outing with Peter over Kitty’s unspoken wish to join them, exposing how love and protectiveness can coexist with possessiveness and regret.

A sisterly bond shaped by family roles

Kitty is the youngest of the Song sisters, and her place in the family matters intensely to her. When Lara Jean imagines that Dan and Trina might have a baby, Kitty confesses that she fears becoming “nothing”: Margot would remain the oldest, Lara Jean would still be the prettiest, and Kitty would lose even the distinction of being the youngest. Lara Jean first protests that she is already the middle sister, then recognizes the insecurity behind Kitty’s ranking of their family positions. Their exchange shows a relationship close enough for Kitty to voice a fear of being overlooked, and for Lara Jean to answer with teasing as well as reassurance.

The sisters’ closeness is also visible in ordinary family scenes. When Margot first visits after Trina has moved into the house, Lara Jean notices Kitty and herself exchanging astonished looks as Margot announces that Ravi will stay in her room rather than use the guest room Lara Jean prepared. Lara Jean had put out towels, a robe, and slippers for him; the sisters’ shared reaction registers how sharply Margot’s decision unsettles the household’s expectations. Kitty is not merely a younger observer: she is beside Lara Jean as the family negotiates the awkwardness of new arrangements.

Lara Jean mediates a changing family

When Kitty says something hurtful to Margot about Trina, Lara Jean asks her why. Kitty explains that Margot has been mean to Trina, whom Kitty calls Tree. Lara Jean wipes Kitty’s tears and reframes the argument: Margot has not had the same time as the younger sisters to know Trina, and Kitty should remember that Margot practically raised her. Lara Jean distinguishes Kitty’s way of speaking to her from Kitty’s treatment of Margot: the two younger sisters are closer in age, while Margot occupies a different, more parental position in Kitty’s childhood.

Lara Jean makes the family hierarchy explicit without treating it as a measure of anyone’s worth. She tells Kitty that she and Margot are almost on the same level, with Kitty one level below because she is the youngest, but that Kitty and Lara Jean are more alike in age and standing than Kitty and Margot. She urges Kitty to understand that Margot does not want to feel her place has been taken. Kitty objects that it has not, but Lara Jean insists that Margot needs reassurance. A teasing remark softens the admonition; Kitty lunges at Lara Jean, laughing, and then goes upstairs to apologize. Later the sisters return with red eyes. Lara Jean’s guidance helps turn a clash into an act of repair, while her explanation makes clear that the conflict is not simply about Trina: Margot has come home to a family that continued changing without her.

Kitty’s wish to belong

The family’s changing composition gives Kitty’s fear of losing her place a wider context. When Margot returns, the living room bears visible signs of Trina’s presence: a shoreline painting on the mantel, embroidered pillows, a photograph of Trina and Dan after his proposal, a different armchair, and Trina’s many small possessions. Lara Jean sees the room through Margot’s eyes and recognizes that it looks cluttered; at the shoe closet, Margot has to push Trina’s cycling shoes aside to make room for her own booties. These details make the household’s transformation concrete. Kitty’s worry about a possible new baby and Margot’s sense of being left out are different expressions of the same unsettled question: who belongs, and what happens to a sister’s place when the family expands or changes?

Lara Jean understands that Margot’s return cannot restore the household exactly as it was. When Margot says it feels as if she came back to a whole new family that she was not part of, Lara Jean recognizes that life at home has continued without her, just as it will continue without Lara Jean when she leaves in the fall. Margot also says that she misses their mother. This recognition informs Lara Jean’s later tenderness toward Kitty: she knows that leaving and changing family roles can feel like being left behind, even when nobody intends to exclude anyone.

The last evening before college

The night before Lara Jean leaves for college, she and Peter plan to watch the Perseids meteor shower at the lake. Kitty wants to come, though she does not ask; Lara Jean sees the tension in her younger sister’s rigid posture. At another time, Lara Jean says, she would have invited her. Kitty’s brief look of disappointment as Lara Jean says goodbye makes the cost of the choice visible: Kitty is the youngest, the one who will remain at home as her sisters move on.

In the car, Lara Jean feels guilty for keeping the evening to herself, and recognizes that Margot would have brought Kitty. She imagines making it up to her at fall break with a midnight drive-in movie: Kitty in pajamas, a blanket arranged in the back seat for when she falls asleep. But the promise of a later outing does not undo the decision. Lara Jean admits to herself that she wants Peter’s attention exclusively for this little while and, if honest, would make the same selfish choice again. Her love for Kitty is real, but so is her desire to hold on to the time she has left with Peter before leaving home.

Lara Jean finally tells Peter that they should have let Kitty come. He agrees that he feels bad, and they suppose Kitty is sad rather than angry. Neither suggests turning the car around. Instead, they laugh sheepishly, Peter says they will bring her next time, and Lara Jean echoes the promise while taking his hand. The scene does not erase the exclusion or resolve Kitty’s disappointment; it holds both the sisters’ attachment and Lara Jean’s impending departure in view. Their relationship is defined not by perfect selflessness, but by the affection that survives imperfect choices—and by Lara Jean’s awareness that Kitty, too, is learning what it means to be the one left behind.
