This was like many other NCIS episodes in that what looks to be a major foreign intrigue or secrets-selling case turns out to be a mere personal domestic issue. The episode is unusual in that there was nothing NCIS could have done that would have changed the outcome of the case. Still it was fun to see the imaginative mystery unfold. Lots of viewers criticize Kate for being taken in by the "amnesiac," but how could Kate know she was crazy?
For those who missed some details (**spoilers**): an employee (Fenn) has an affair with her married boss. Fenn insists on the boss divorcing his wife and marrying her. But he has his subordinate fire Fenn and give her 6 months severance pay. Crazy Fenn kills the subordinate, and then attacks the boss, who fends her off, accidentally knocking her unconscious. Thinking her dead, he quickly buries her. Later she comes to, with amnesia. Kate looks after/befriends Fenn, who slowly regains her memory, and then kills the boss!
One good part was Tony waking Gibbs with the news that began the case and then pestering his teammates to allow him to stay at their place for a month while his apartment could be repaired.
