I was very happy to see that the serial killer's prime target wasn't Abby. I had been leary of this situation because Abby had been in danger serveral times before by insane men. I was happy that NCIS made note of this, and had Abby recall the serveral instance when she had been in jeopardy.
Gibbs was the target. It was nice to see Dinozzo and David worry about their boss. It was a great ending. Tony tried to tell the killer he was being repetive, but he schooled Tony reminding him that his scenerio was different, because the victim would have been murdered by Gibbs. I'm glad Tony has more to do than watch movies!
