Ana Dussuel is a psychiatrist, and ends up taking on murderer Sergio Ciscar as her first case. She and her team are given permission to conduct an experiment with him.

Throughout Muted
Ana and her team of psychiatrists, including Greta and Mikel observed Sergio through cameras. They saw Sergio meet up with Marta Ortega, a fan of him. Marta handed him a handwritten note with Noa's phone number. Sergio and Noa lost contact after the murders. However, Sergio could not contact Noa using the number, as Marta had been out of contact for a while. Sergio felt deceived and confronted Marta about it. He revealed that he received many letters from fans, but only responded to Marta, because Marta knew Noa from teaching her piano.

After Ana Dussuel talked to Marta, she went to Sergio's apartment. They watched Sergio and Noa's childhood videos. Just as Sergio was about to open up emotionally, Marta received a call from Eneko. She left, but to the disappointment of the psychiatrists, who were keen to find out Sergio's motive for murdering his parents.

When Marta's boyfriend, Eneko, learned of Marta and Sergio's relationship, he became very angry. He and a group of friends confronted Sergio outside his apartment building and beat him up. Meanwhile, Marta copied Sergio's childhood videos to the psychiatrists. The group of psychiatrists became increasingly concerned while watching Sergio getting beat up, but Ana insisted on getting all the videos before intervening. Later, Eneko and his friends reported to the police that Sergio assaulted them, sending Sergio to prison again.

The psychiatrists watched Sergio's childhood videos, and saw that he was being abused by his parents. His mother, Blanca Polo, treated Sergio as a test subject, giving him medication and insulting him to test how he would react to a change in emotion.

Quotes
"Monday, April 16th, 2022. The subject goes back to the family home. We begin the program of daily monitoring and behavior analysis. Silence is Sergio Ciscar's way of dominating us. We might think he does it to avoid being attacked, but no. He does it so that we all keep an eye on him. He's a malignant narcissist. If he knew we were watching him now, he would enjoy it. Our job is to determine his current psychological state and his potential level of threat. Sergio is extremely intelligent. He has an IQ of 154. His mother, Blanca Polo, was a psychiatrist. As soon as she realized her son's immense capability, she focused on his education. Something went wrong almost immediately. Sergio alternated academic success with a progressive emotional detachment from his family. He became the Balcony Killer six years ago. Since then, he's been silent. Since his parents' death, he hasn't spoken once. Not in the trial, not with his tutors, not with anyone."
