The case hanging over Ducky's is finally getting somewhere. Thanks to that assistance, Ducky realize who one of the victims is and then.. it is puzzle to put together and soon they find that Ducky is in the victim list. So.. it is a case of solving the murder where the main suspect is (not) certainly dead and in the same time, protect Ducky.. what Kate fails. That moment there.. oh.. she just seems to be making too much mistakes considering she was protecting president.
But they get happy ending.. they race with time and the win. And loved the ending.
