This episode was really great, in my opinion. I enjoyed seeing Gibbs have McGee make the decision as to whether the case should be investigated or not.
I thought there was great chemistry between the witness and Special Agent McGee, and that made it very sad to see the witness turn into the next victim.
I thought the episode did lack something, but I find it hard to pinpoint, although I really enjoyed the chase at the end of the episode.
The episode was a very touching one and a really interesting one to watch, and I recommend this one very highly, particularly for McGee fans.
Another great addition to NCIS!
