How does minerva feels when Elsa says "viva la mariposa"?

On April 2, Maria Teresa writes about the Crucifix Plot. As a demonstration of solidarity, the prisoners have been wearing crucifixes and singing. Because of the suspicion surrounding the Catholic Church, Trujillo ordered that the crucifixes be taken away. When Minerva resisted, fighting with the guards, she was put in solitary. As she is being led there, the prisoners call out, "¡Viva la Mariposa!" This makes Minerva feel like she is making a difference, it makes her feel like her rebellion is not in vain.
