Lee and Elle's Seventeenth-Birthday Costume Party

Lee and Elle's Seventeenth-Birthday Costume Party is a joint birthday celebration at Lee's house, staged as a costume party and attended by their friends. Its most consequential moment is Noah's arrival: his brief kiss with Elle takes place in front of the assembled guests, making their relationship visible beyond the limited circle that had seen them together since the Summer Dance. The party's playfulness gives that public turn a particular shape—among movie characters, costumes, and birthday teasing, a concealed romance becomes hard to conceal.

Preparing the House

When Elle arrives at Lee's house, preparations are underway for guests expected at seven. Cam and Dixon are due to help move the couches and set up the speakers. Elle takes her costume from a bag and holds the dress against herself, unsure how it will look. Nearly an hour later, her dark curls are clipped back over one shoulder, and she is ready in a Robin outfit; Lee is dressed as Batman, though the costume makes breathing difficult. Their paired costumes make the birthday gathering feel like a shared undertaking, even as the party belongs to both of them.

Lee and Noah have bought several sets of speakers for the large docking station in the lounge. They and Dixon untangle the wires, set up the equipment, and push furniture to the edges of the lounge and game room; the kitchen is cleared as much as possible. Lee's parents leave when Elle's father arrives, and the doorbell rings soon afterward. Cam and Dixon's coordinated costumes suggest they have planned their appearances together. The arrangement of the rooms turns the Flynn household into a space for dancing and a crowd, rather than an ordinary evening at home.

A House Full of Costumes

The guests arrive quickly, and music soon fills the house. The crowd is described as less like a group of teenagers than a menagerie of movie characters: there are Disney princesses and fairies, Candice as a zombie version of Alice in Wonderland, and her boyfriend as the Mad Hatter in a costume modeled on Johnny Depp's portrayal. Karen comes as Ginny from Harry Potter. The details establish the party's comic, theatrical register: friends temporarily take on recognizable fictional identities, while the familiar house is rearranged for their gathering.

The party is also a reunion of the social circle around Lee and Elle. Noah is not part of the preparations described at the start, and Elle eventually encounters him in the backyard, where Dixon is by the pool with friends, tipsy and singing a pirate song. Noah approaches Elle from behind, wraps his arms around her, and greets her as the birthday girl. She turns and pushes up the hat obscuring his face, recognizing him without needing to see it. Her teasing response that he has finally decided to show his face makes his arrival feel like a moment she has been awaiting, rather than just another guest entering the party.

Noah's Public Arrival

Noah is dressed as Al Capone. Elle begins to comment on the costume, but he interrupts with a brief kiss. The gesture is intimate, yet its setting changes its meaning: Elle realizes that practically everyone is watching. Since the end of the Summer Dance, few people have seen them together. At that earlier dance they had made their relationship official; here, in the middle of a crowded birthday party, they are openly affectionate in front of their friends. The kiss does not introduce the romance, but it makes its visibility unmistakable.

The surrounding costumes and teasing keep the moment light, but they do not undo its significance. Elle giggles rather than retreating from the attention, and the party becomes a public scene of recognition: the people around them can see what had previously been kept out of view. The contrast is sharpened by the history of secrecy and conflict. Elle had earlier insisted that she would not risk her friendship with Lee merely to become another girl Noah slept with and abandoned; during the later confrontation, Lee accused Noah of hypocrisy for protecting Elle from other boys while secretly being involved with her. Noah fought with Lee, and after their argument he left home without saying where he was going. By the time of the birthday party, Elle and Lee have found their way back to one another as best friends. Noah's public affection now takes place against the history of concealment and damage, not outside it.

Affection and the Uncertain Ending

Later, Noah tells Elle quietly that he loves her. The declaration is not made to the whole party; it is a private exchange within a gathering that has already made their relationship public. Elle is moved by his expression and laughter, and Noah tells her he will catch up with her later so she can go back to enjoying her birthday. The shift from a kiss witnessed by the crowd to an intimate declaration preserves both sides of the relationship: its newfound openness and its private emotional closeness.

The party offers a brief, joyful image of connection, but the next chapter opens with Elle wishing it could have been a fairy-tale ending. That turn prevents the celebration from serving as a simple resolution. The gathering marks an important change in what others can see and confirms Noah's love to Elle, while the qualification at the chapter's close signals that happiness at this party cannot guarantee an uncomplicated future.
