I think I discovered the problem with NCIS (well, I shouldn't say problem because this is still a good show, but it could be better) and it is the same problem newer Family Guy episodes face off. They start off with one storyline and then things completely change and by the end of the episode you do not even remember how you got to that point.
Tonight we started with the director barely avoiding death and we ended with an agent trying to expose an anthrax scam? Whaatt?
Still a pretty good episode, but stick with one plot NCIS and end it.
