In this tense chapter of La Promesa, María Fernández faces a desperate struggle to gain Petra’s approval to visit Samuel, who is still recovering in the hospital. Despite her arguments that Jana and Manuel support her, and that she could arrange for transportation, Petra remains unwavering in her refusal. María tries to appeal to Petra’s sense of humanity, highlighting Samuel’s past help and the gratitude everyone feels toward him, but Petra dismisses her plea as mere sentimentality. She warns María that any further insubordination could lead to dire consequences. María, tearful with frustration, realizes how difficult it will be to act without Petra’s permission. Yet, her resolve to help Samuel remains strong, and she promises herself that she will find a way to defy Petra’s watchful eye and visit the hospital.

Later in the day, the family says a painful goodbye to Catalina, who is leaving the palace for good. Manuel struggles to hold back his tears as he bids farewell to his sister, feeling the weight of her departure. Catalina, who is pregnant, explains that she needs to leave the oppressive environment of the palace for the sake of her child. Manuel understands, despite the pain it causes him, and they exchange promises to stay in touch. As Catalina’s carriage drives away, Manuel’s heart breaks, and he silently curses Cruz for causing so much turmoil in their family.

Meanwhile, Cruz and Petra meet to discuss their plan to expose Leocadia. Petra reveals that she has uncovered a crucial piece of Leocadia’s past—a secret relationship with Eugenia. If they can get Eugenia to speak or reveal the truth, it could destroy Leocadia’s reputation. Cruz, excited by the opportunity, agrees to pursue this path, seeing it as the perfect weapon to dismantle Leocadia’s power.
