On a rainy day on the island, Emma and Justin distract themselves by playing with Nerf guns inside the house. Their joking turns physical when Justin catches Emma on the bed, but the flirtation stalls again because both of them have been circling unresolved desire since recovering from being sick. Emma reflects that neither of them has addressed the deeper problem: she is still supposed to leave, and Justin cannot offer the detached arrangement she usually relies on.

After pulling away, Justin unexpectedly asks when Emma wants him to leave. Instead of answering directly, Emma tells him he can stay, and they talk about practical obstacles, including Justin's responsibilities back home. Justin reveals that he paddled to the island on a unicorn float, underscoring how determined he was to get to her, and then admits that he thinks about her constantly. When he finally asks what they are doing and whether what they share is "magic," Emma is forced to confront feelings she has been avoiding.

As Justin begs Emma to stay for however long she can, Emma tries to imagine building a life in Minnesota. She realizes that what truly frightens her is not logistics but attachment: if she stays, she will fall in love with Justin, his family, and the life around him. Emma understands that her habit of leaving before she can be hurt comes from the unstable way her mother raised her, and that her rootlessness has been a form of self-protection.

Once Justin stops holding himself back, they finally kiss and become physically intimate. For Emma, the experience feels entirely different from her past relationships because it is emotionally meaningful rather than transactional. Being with Justin makes her imagine ordinary future intimacy with him beyond sex, which shows her how deeply she already wants a life that includes him.

The intensity of that realization overwhelms Emma, and she suddenly breaks down crying. Justin immediately stops, worries that he has hurt her, and gently tries to understand what is wrong. Emma tells him that something in her heart feels broken and then admits that she likes him more than she has ever liked anyone, which terrifies her. Justin answers that he feels more than "like" too, and their mutual confession shifts their relationship into open emotional honesty.
