Ex-File is the third episode in Season Five and also the ninety-seventh episode of the entire NCIS series.
A Marine Captain is found dead on an Army base with one of the witnesses being Gibbs's third ex-wife. As the NCIS team open an investigation to find the killer, Gibbs's past and present relationships threaten to collide with each other.
Once they're inside, they head for the study where Jill's husband, Trent Reynolds is and ask him to turn down the blaring music which Jill eventually turns down.
Stephanie edges closer to say hi to Trent but gets a shock where she discovers that he's dead with an arrow having gone straight through the upper side of Trent's body.
It then cuts to Stephanie who looks greatly horrified at the discovery.
- Ziva is seen wearing a silver watch for the first time, a watch similar to what Kate wore during her tenure on the team.
- McGee is also seen wearing a sports-styled watch for the first time.
- When Abby is exiting the computer area to go back into the main section of her lab and just before Fred Rinnert asks her if she needs help, if you pause it, you can clearly see a reflection of the cameraman and the boom mike man in the glass doors.
