On NCIS: New Orleans Season 2 Episode 4, the horrifying discovery of a corpse ruins the mood at the wedding reception for a Seabee. When the NCIS team learns that the victim was a drone pilot, their concerns turn towards possible terrorism. But, like most cases they investigate, there's more going on than meets the eye. What was the reason for Lt. Griggs's death? Was it terrorists? Or could it be linked to the angry protesters outside the base, who are aggressively against drone warfare? Or is there something even more ominous and mysterious going on? The case becomes personal for LaSalle as he bonds with Lt. Griggs's young son Ryan, who is trying to cope with his father's murder even as LaSalle is avoiding dealing with the murder of the woman he loved. Pride tries to counsel LaSalle about handling his pain and grief, but will LaSalle take Pride's advice to heart, or let it consume him? Meanwhile, Brody tries to suss out what exactly is Sonja Percy's problem with weddings. Find out the truth about the death of Lt. Griggs (and maybe something about Percy, too) when you watch NCIS: New Orleans Season 2 Episode 4 online here at TV Fanatic!
