Diego

 is the acolyte to Father Clifford at Saint Monica's Church in Rivet City. There are rumors of his involvement with a girl in Rivet City (the daughter of the cook) 'Angela Staley'. The dweller can either force him to relinquish the church or the girl (by saying you will tell the father, or telling the father directly). If you convince him to choose the girl they will end up getting married and you have the option to attend the ceremony. You can also give Angela Staley some Ant Queen Pheromones which will make Angela irresistible to Diego. Diego will leave priesthood to marry Angela.
