Father Geraldo is the Catholic priest for the parish of Kimmage in Rat. The good father is a fiery, somewhat eccentric man, and the immediate mentor and superior for Pius Flynn, who aspires to become a priest. Father Geraldo is mystified by the familiarity of Pius' surname (which the latter suggests is due to the fame of Erroll Flynn). Presiding over Sunday mass, the priest is not afraid to loudly call attention to anyone talking or canoodling during the service, and threatening to bounce them around.
