When you watch NCIS: New Orleans Season 2 Episode 21 online, an old friend calls Pride in the middle of the night to investigate the sudden death of a Navy lieutenant who died in the hotel room of an Army general who is up for a high position at Homeland Security. The friend, Colonel Nilsen, insists on total discretion to preserve the general's career prospects, and he is upset when Pride shows up with the entire team plus Loretta in tow. Loretta determines that the lieutenant was poisoned with arsenic... and that the general was also exposed. As the team attempts to delve deeper into the case, their investigation is constantly being frustrated by Colonel Nilsen's interference in the name of discretion. It's now up to the team to figure out who poisoned Lt. Peterson (and General Matthews) and why. Was it jealousy? Or was the motive less mundane? And were the two of them dating, contrary to regulations? Why would anyone want to murder someone who worked for Port Services? The team seems to be finding more questions than answers, and the word discretion soon becomes a barrier blocking their every move.
