At 'La Promesa', Martina tells Jacobo she has been unfaithful with Adriano, setting off a crisis. The revelation comes just after Jacobo’s sudden return from his parents’ home, leaving Martina and Adriano overwhelmed by guilt. Mediaset Infinity’s recap of the October 12-18 episodes says Adriano invited Martina to spend an evening together after Jacobo left, and the two kissed. When Jacobo returned, Martina initially kept the encounter from him. The triangle centers on Martina (Amparo Piñero), Jacobo (Gonzalo Ramos) and Adriano (Ibrahim Al Shami). Jacobo reacts explosively to her confession, fracturing the household’s fragile balance and triggering emotional fallout among those closest to the couple.
The affair soon widens into a family conflict. Ana Villa joins the storyline as Casilda, Jacobo’s mother and the baronesa de Monteclaro. In comments reported by El Confidencial, Villa called the basic relationship “a rather unusual triangle” and said another character was needed. Casilda tries to protect her son and separate Martina from Adriano, while pressing Jacobo to set a wedding date with Martina. Previews for the week of October 19-23 add another complication: Martina is pregnant by Adriano, and Casilda argues that Jacobo should marry her. Adriano, in turn, urges his brother to confront their mother and refuse a marriage imposed on him. The pressure eventually pushes Martina to confront Casilda.
Meanwhile, divisions within the family deepen. Máximo’s refusal to acknowledge Ángela as his daughter sparks outrage at the dinner table, where no one supports his stance. Curro’s attempts to comfort Ángela fail as she struggles to accept Máximo’s denial. Leocadia urges Máximo to apologize and recognize Ángela, but he remains unmoved. Tensions rise further when Lorenzo mocks Máximo, prompting a violent threat. Alonso intervenes to restore order. The duque de Buenaventura also clashes with the staff, demanding silence and challenging Cristóbal’s authority.
Conflict is rising in the service quarters, too. Ricardo, Pía and Teresa notice Petra pulling away and increasingly siding with Tomasa. Señora Arcos pleads with her sister not to turn against their colleagues, but Petra ignores her appeals as she seeks revenge. In the kitchen, Julio openly sabotages the cooks. Alonso reprimands Simona and Candela for repeated mistakes. The duque de Buenaventura uses the moment to request a private meeting, leaving the two friends anxious about their future.
Janita’s baptism brings another source of tension. Carlo steps up his campaign to marry María during the ceremony, but his pressure only angers her. Samuel officiates the baptism, and Manuel is named Janita’s godfather. The decision brings joy to most, but leaves Carlo disappointed and isolated.
Financial intrigue unfolds as Ciro and Lorenzo finalize a scheme to defraud Manuel by double-charging companies, ensuring he receives only a portion of the funds. Manuel confronts his cousin after Enora tells him about plans to sell a manual at an inflated price. Ciro placates Manuel by arguing that the companies can afford the expense. The situation grows more volatile when Lorenzo intervenes in a heated argument between Ciro and Julieta, which nearly turns physical.
The palace’s romantic conflicts unfold alongside the series’ larger family mysteries. Diez Minutos has recounted how Curro’s investigation led to Leocadia being identified as Jana’s killer. Jana’s death became a turning point in the Luján family’s story. These revelations place the current struggle over secrecy and marriage within a broader pattern of delayed truths at 'La Promesa'. The series premiered in 2023. Espinof reported that it had reached 931 episodes, with one episode earning a 12.3% share and leading La 1’s afternoon schedule at the time of its October 2026 coverage.
The developments at 'La Promesa' reflect the power struggles and personal betrayals shaping the series. Shifting alliances and strained relationships affect life across the household. Similar themes have appeared in other Spanish dramas, including stories about local women in Ceuta who stepped in to protect vulnerable minors, as reported in coverage of the Ceuta crisis.
Set in early 20th-century Spain, 'La Promesa' portrays class divides and personal ambition, along with the consequences of hidden truths. It also explores loyalty and family life in a changing society.
