"Savoir Faire" will put Sam (LL Cool J) back in the field following his close brush with death, and it looks like the former Navy SEAL may have a disagreement with Callen (Chris O'Donnell) as episode 17 progresses.

"While the team investigates the death of one of three Afghanistan soldiers who are training in the U.S., they discover two other soldiers are missing and must find them before they're forced to reveal classified military operations to their captors," CBS teased. "Also, Sam is back to work but his team worries it may be too soon, and Callen realizes he has very little in common with his partner."
