Hey guys. So here's something interesting I found when going through old files: a series timeline for NCIS that I made, detailing events and history of the show and the characters. I've been watching this show since the beginning, got obsessed, and at some point I thought it would be cool to make this.
You can check out the timeline here: http://i.imgur.com/uchy5r8.png
As you can see, it's outdated and doesn't contain anything past 7x19. That's because I stopped watching the show in early 2011 (it just wasn't interesting for me anymore). Then today I just found this thing again and thought why let all that work go to waste, someone here might appreciate it.
So, enjoy, NCIS fans!
PS. I give no guarantees about correctness or completeness...
