Last night on NCIS, we were introduced to Gibbs' ex-wife Diane, who also happens to be Fornell's ex-wife. Her visit led to some classic comedic moments, but also told us a lot about our leading man.

Simply put, it was a terrific episode. Read our NCIS review from this morning for our full take on the "Devil's Triangle," and share your comments on Gibbs, Fornell, Diane and the rest of the team.

Next Tuesday, in the first half of a two-part episode, the NCIS team uncovers a discrepancy with DNA remains when investigating the crash of a military plane that had been transporting caskets.
