A hardline stereotype Traditional Irish Catholic who has devoted his whole life to work and not his son, he began working for the pope after being introduced to him. He hates Peter's wife Lois because she isn't Catholic; he even went so far as pinning a big sign on her wedding car reading "Just Married--To A Protestant Whore."
