Ongoing reminder that Provenza does NOT like anyone placing anything on his desk. Nor does he like anyone to lean/prop/sit on his desk either. Flynn pokes fun at Provenza for this.
Provenza rather insistently corrects the use of "paparazzi" to identify the murdered photographer, insisting the term is "paparazzo". And he's right: in Italian, the plural form of a masculine noun ends in the letter i, but the singular form, such as would be used in referring to the victim, ends in the letter o. This scene, along with one in Aftertaste suggest Provenza has at least a working, and perhaps somewhat sophisticated, knowledge of both French and Italian.
