From the new TV Guide (Oct 16 - 22):
CSI: Crime Scene Investigation - They may be secret lovahs, but Grissom and Sara still find ways to surprise each other, like tonight when their religious beliefs surface while investigating a trio of murder suspects: a priest, a nun...and a car dealer?
And then the little article (above) directs the reader to page 68, where it says: "Religion gone wrong is truly disturbing tonight when two nuns find a woman crucified on a makeshift cross in a church - where the priest may be a man of sin instead of a man of God."

Looks like this episode might be interesting. Hope so. And I doubt we'll see Greg in this episode. Oh well, he'll probably be recuperating.
