Thanks to Iluvaqt for posting the following cast update to the forum:

Entertainment Tonight has an article on NCIS regarding the fall lineup, and included is a quote by Michael Weatherly, who plays Tony Dinozzo:

As for his role in the second season, Weatherly says with a smile, “I think it is important for DiNozzo to date a lot of pretty girls, and I think he should shoot his weapon. Really, I am just happy to have a job and report to work everyday.”

Hmm… Now, which ‘weapon’ was Michael thinking of shooting I wonder?
