Why is Pedrito so upset? How does Patria justify herself to him?

Patria volunteers Pedrito, Nelson, Minerva, Manolo, Maria Teresa, and Leandro for the organization. However, Pedrito becomes upset that the revolutionaries are meeting in their backyard, since a new law has been passed that will allow the government to confiscate the land of anyone found to be harboring any enemies of the regime. Patria is able to sway him when she reveals that their son Nelson is involved, too.
