What does Captain Pena do for Patria? What does he ask for in return?

Captain Pena comes to Chea Mirabal's house, but Mama refuses to see him, so it is Patria who must receive him. He brings visiting passes and reports that Nelson might be released with the next round of pardons. But Minerva and Maria Teresa have refused their own pardons. When Pena asks Patria how they should celebrate when Nelson returns home, she invites him over for a sancocho. That night, Patria confesses to her mother that she has "made an indiscreet promise," offering the Lord her own self in exchange for Nelson.
