Louisa reacts loudly and fearfully to receiving The One of the Sea, briefly dropping it before chasing Ted and demanding he take it back. Ted clarifies that C. Jat gave it to Louisa and suggests she sell or keep it, but Louisa reveals she has no home and is terrified by the burden and risk the painting brings to a homeless teenager. Ted proposes she sell it back to the auction house after Easter, but Louisa protests she cannot keep it safe until then.

When Louisa points out that people will think she stole it, Ted realizes the lack of paperwork proving the gift. He explains he and the artist kept the purchase secret to avoid price inflation due to the artist’s impending death. Overwhelmed by grief, Ted tries to leave for home, intending to take the ashes to the place depicted in the painting.

Louisa asks to come along; Ted refuses and hurries to the train station. In a chaotic pursuit through traffic and the turnstiles, Louisa confronts Ted about the painting’s figures, asking if he is one of the boys. Ted admits he is, identifying himself and naming Joar as the boy who “farted,” briefly sharing a tender, humorous memory that nearly makes them both laugh.

Louisa apologizes for the police incident; Ted replies that the artist felt alive and reckless again, albeit being “such an idiot.” Ted says he and the artist knew each other since childhood. Louisa confides that as a child she imagined being with the boys by the sea, learning to swim.

At the platform, Louisa again asks to travel with Ted to find someone who can help sell the painting; Ted reluctantly concedes there might be someone back home but still refuses to take her. Their exchange spirals into a comic debate about kidnapping, size, and responsibility, with Louisa asserting she has just turned eighteen and can travel where she wants.

Pressed on why he won’t let her come, Ted finally shouts that he cannot take responsibility for her as well. The admission breaks his composure, and Louisa sees him cry for the first time.
