Angel of Death is the ninety-fourth episode of NCIS and also the Season Four finale episode.
Having returned home, Jenny gets a shock when she realizes that she had a visitor whom she suspects might be her supposedly dead father. In the meantime, all NCIS agents are scheduled for a Homeland Security polygraph test which the CIA has arranged for some reason. Tony and Jeanne later find themselves fighting for their lives when they're taken hostage by a drug dealer, who is desperate to remove his shipment of drugs from the dead body packer.
At an airport in Washington D.C., it's all hustle and bustle as passengers get to depart or are just returning. Among them is NCIS Director Jennifer Shepard who confidently walks through the crowd with an NCIS agent carrying her luggage.
As she arrives at a limo, her assistant Cynthia Summer stands there, greeting Jenny and wondering how the Interpol conference was.
Jenny remarks that it was fine and full of Eurocops trying to hook up with her.
She then looks at Cynthia and states, "And, no, I didn't".
Cynthia stammers, stating that she wasn't....
Jenny tells Cynthia that she would if she was Cynthia before telling Cynthia to get in.
As the male NCIS agent puts the luggage in the trunk, Cynthia joins Jenny in the back and as soon as she's in with the door, Cynthia gives Jenny a briefcase.
As she takes it, Jenny wonders if the agency's still intact after a week with Gibbs in charge.7
Cynthia remarks that they survived.
Jenny just laughs before asking if Gibbs did.
"Barely", Cynthia replies.
Jenny just smiles.
Outside, the NCIS agent has finished putting all the luggage in the trunk and once he's slammed the trunk shut, he gets into the limo and then drives off with both Jenny and Cynthia in the back.
As they head off, a lone young girl with curly hair and holding a doll is seen walking on the terminal.
As this happens, Devon Watson emerges and looks around before he produces his PDA from his pocket and begins typing something.
However, as he crosses the road, a taxi emerges and strikes Devon, sending him to the ground as the passengers look on him, some screaming in horror while the taxi driver gets out, startled and heads over to Devon who's now lying on the ground, unconscious, his left leg.
Back on the pavement, the little girl is standing there, watching as the PDA is spinning around.
The little girl blinks twice and the PDA stops.
It cuts to the PDA with the message still unfinished and prepared to being sent to someone named "Bernie" as being "Cleared customs. See you soo".
In the bar, it's relatively empty except for Ziva, Ducky and a few patrons.
At the main area, Ziva remarks that she has a funny feeling.
Ducky tells her that it's the tequila and that she's had three shooters in the time he's been there.
As he says that, Ziva tries calling Tony again with Ziva remarking that it's gone straight to voicemail and that it's just the same when Tony's with her.
