Yes Father 5: Ordination
Father Landon is an experienced priest and knows how to recognize signals from the boys, so he's well aware of young Jace's fondness for him; when Landon lets Jace know that he's been selected to become an altar boy, Jace is so excited that he's more than willing to prove he's worthy of the honor. Felix is quiet, unassuming and dedicated to reading the scripture and progressing as far as possible down his path towards enlightenment, so it's no wonder that Father Fiore and Father Landon, on separate occasions, find themselves drawn to this timid boy and eager to teach him their special secrets in Yes Father Vol. 5: Ordination.
