Dr. Grace Confalone returns to consult with the special agents in an all-new episode entitled "Twofer."

Gibbs ( Mark Harmon) and McGee ( Sean Murray) may be home safe and sound after their traumatic imprisonment in a Paraguayan rebel camp, but that doesn't mean they're back in action just yet on NCIS.
