In this scene, we find Julio at the office where Llanes worked. He asks Llanes' boss whether he can speak with Llanes, but is told that Llanes no longer works there and is escorted out. He sneaks back in after everyone has left and finds the letter in which Don Carlos tells Llanes that he plans to recognize Andrés as an Alarcón.
In this scene Llanes recounts for Julio how he found out about the letter that named Andrés as the heir to the Alarcón fortune. He tells Julio that when Don Carlos died, he forgot his anger at Don Carlos, until one day when a maid from Gran Hotel came to seek advice about his boss. This maid happened to be Belén, Andrés' wife who was expecting a child.
