Character Analysis
Sister James teaches Jack in Salt Lake City:
She feared we would spend our time with friends from the public schools we attended and possibly end up as Mormons. (2.7)
Despite her fears, she's pretty open-minded and tolerant. She does her best to guide Jack on the right path and her silent disappointment gets to him far more than Dwight's screaming and pounding ever will. She demonstrates that Jack does have good role models in his life, but that, for whatever reason, he ends up ignoring them. Yeah: he lies to a nun:
I nodded and presented her with an expression that was meant to register dawning comprehension. (2.85)
But he's trying to tell her what she wants to here, which is pretty good considering the other kinds of lies he tells.
