Daniel discovers Clara and Adrián Neri together at the moment his imagined intimacy with Clara collides with the reality of her life beyond him. He had entered the Barceló residence to retrieve Julián Carax’s book and give it to the threatening stranger who had demanded it. Instead, he finds Clara with her music teacher, is forced out of the apartment, and leaves with his infatuation broken but his feelings unresolved. The episode ends not with hatred or clean escape, but with Daniel carrying the book back to the Cemetery of Forgotten Books.

Background and Purpose

The discovery takes place in the Barceló residence during a storm. Daniel knows the apartment as a place he has come to regard as a second home, but that familiarity does not make him welcome in its private rooms. He moves through the darkened residence toward the library, where Clara keeps Carax’s book in a glass cabinet near the balcony.

Daniel’s immediate objective is practical and urgent: he plans to take the book, deliver it to the stranger, and be rid of the man. His private motive is more complicated. Before leaving the library, he imagines departing Clara’s life forever, yet pictures the intimacy he has long fantasized about with her. The book he presses to his chest seems, in that instant, both a treasured companion and something he is preparing to betray.

Discovery and Confrontation

With the book in hand, Daniel starts away without intending to alert Clara. A voice from behind a door stops him. He approaches her bedroom and opens it, discovering Clara with Adrián Neri. The encounter overturns the scene Daniel had imagined: he had pictured her asleep and himself as the intimate presence in her room, but finds that her relationship with Neri is real and that he has no place in it.

Neri notices Daniel and breaks off what is happening. Clara, unaware of the reason for his interruption, asks why he has stopped; Neri tells her he will be back and turns his anger on Daniel. Daniel remains fixed on Clara as Neri grabs him and drags him from the bedroom through the conservatory. At the front door, Neri throws him onto the landing. Carax’s book slips from Daniel’s hands, and Neri picks it up and throws it back at him.

Neri warns Daniel not to return or approach Clara in the street, threatening a further beating. He then demands the keys. Daniel refuses, and Neri strikes him again before searching his pockets and taking them. He leaves Daniel outside the closed apartment door. Daniel retrieves the book and makes his way down the stairs and out into the rain, hurt and struggling to breathe. The book, originally the purpose of his entry, is also the object Neri returns to him as he casts him out.

Aftermath and Emotional Reversal

The rejection does not produce the hatred Daniel vows to feel. Looking back at the Barceló apartment from the entrance to the square, he sees its windows still dark in the rain and admits that he wants to hate Clara but cannot. In his account, true hatred is an art learned over time; at this moment, the attachment that has shaped his fantasies remains stronger than his anger.

Daniel nevertheless swears never to see Clara again, speak her name, or remember the years he believes he wasted beside her. His resolve coexists with fear that jealousy and shame will return when the details of the night settle into his memory. For now, however, he feels unexpectedly at peace: the anger that drove him from home has ebbed, even as he anticipates its possible return. The episode thus marks a sharp change in his understanding of Clara without resolving the feelings he has built around her.

The Book and the Return

Before going home, Daniel makes another choice. He goes to Calle Arco del Teatro and the Cemetery of Forgotten Books, the place his father first brought him six years earlier. In the rain, he knocks repeatedly at its old door, then takes Carax’s book from inside his jacket and rereads the opening sentence that had first captivated him.

The return links the personal humiliation in Clara’s apartment to Daniel’s continuing bond with Carax’s work. He had entered the residence intending to surrender the book to the stranger; after Neri’s attack, he still has it and carries it back to the place where his connection with it began. Clara’s discovery ends his romantic idealization in its former form, but does not sever his attachment to the book or settle the danger surrounding it.
