When you watch NCIS: New Orleans Season 2 Episode 12 online, the personal and the professional collide for Sonja Percy as she is tasked with taking down Marian, one of her oldest friends, who is now a major player in the drug trade in New Orleans. But it all starts with the death of a SeaBee and the theft of a whole lot of Navy TNT ordinance from a construction site. The team follows the trail and discovers that the TNT is being used not to blow anything up but for the toluene it contains in order to process cocaine. The team is also shocked to encounter their own Sonja Percy undercover in the middle of this, working alongside a DEA operation to take down a huge drug ring in New Orleans. Pride is understandably upset that she hadn't told him what was going on. And for Percy, the mission is especially personal because of the involvement of Marian, who she once thought of as a sister before Marian fell deeper and deeper into the morass of drug addiction. The team joins forces with the DEA to locate and take down the leader of the drug ring. Find out what happens when you watch NCIS: New Orleans Season 2 Episode 16 online!
