Fire and Brimstone

Gwyn, a fundamentalist Welsh preacher who abstains from everything and spends much of his time praying or hymn-singing, moves in. He talks Ruth out of going on a dirty weekend with Rigsby because it would be immoral and has some success in converting Rigsby to the faith. However, when Ruth gets excited as he explains to her a passionate extract from the bible and throws herself at him, he moves out.
