Red realizes what he wants and does not like what he is doing. He considers that it will not do any good since Olvido, a couple of weeks ago, was diagnosed with Alzheimer's. Red is quite touched by his mother's illness and also because she herself decided to go to a residence. Valentin goes to the residence to look for Olvido. It helps her get ready and groomed to take her to the Lollipop Cabaret. She does not know whether to trust her husband but she ventures to enjoy the surprise they have in store for her. The first musical number in which Red and Valentín are rehearsing tells how Olvido arrived in the city fleeing her partner since he mistreated her because he did not accept that she was an actress and star. Once he has arrived in the city he meets Valentin and hand in hand they start a new life. When Red finishes the musical number, he becomes involved with his father because he cannot understand what it is that leads him to do that. They continue rehearsing the second musical number that draws how Olvido is affected by fear and uncertainty prior to being diagnosed with the disease. Moments before the end of the musical number, Olvido greets Red from under the stage. Red breaks down and argues with his father because he doesn't understand why he wants to make the whole family suffer. Valentin together with Olvido sing the soundtrack of their lives and how we must move forward, without haste but without pause, to achieve happiness regardless of the circumstances that surround us.
