"Maeve is a recent theology Ph.D., and her thesis adviser turns out to be Paul (the edgy K. Todd Freeman), the astringent black longtime partner of Gus's older son, Pier Luigi (Stephen Spinella), a.k.a. 'Pill'. When Maeve is first heard from, she's talking shop to Gus's sister, Clio (the subtle Brenda Wehle), a former nun and Maoist, who has been watching over Gus since his first attempt to slit his wrists, the previous year. 'Maeve Ludens, Doctor of Theology, unemployed, not exactly a bull market out there for us apophatic theologians, with a, with, you know, pronounced kataphatic inclinations', Maeve says, adding, 'But I'm kataphatic by nature, I'm just a cockeyed kataphatist! So sue me!' Nobody, not even Clio, knows what the hell Maeve is talking about; her speech, however, plays as a hilarious piece of pretension."

Don't get me wrong: I'm 100% onboard with going with the Greek spelling, but you might want to be careful whom you're accusing of pretension, Mr. Lahr. It's like spelling it "Akhilleus" instead of "Achilles".
