The plot of this episode is interesting and entertaining, but does have some holes.
Apparently the actor who plays the Russian scientist could not do a Russian accent. We're supposed to believe that she is trying to defect, but she speaks better English than the NCIS agents. Not a believable Russian at all.
Another hole is after the scientist is supposedly shot and killed. Wouldn't the Russians want the body returned? How did Gibbs know that they wouldn't?
The writers also never satisfactorily identified the leak. Who was passing information to the assassin? Who hired the assassin? We think it might be either the Russian government or a rogue faction? The story isn't very clear which.
Still, it is an enjoyable outing.
