Along with LaRoche’s introduction has come McGee’s distrust of him.

In the case of LaRoche working undercover, it would have to be for a department outsideNCIS.

That is the only way to explain why Vance also does not trust LaRoche.

InNCISseason 22, episode 18, Vance provides McGee with LaRoche’s file to find evidence of government corruption.

However, that would only make sense ifVance was not aware of the undercover operation.

Somehow, all three names were connected to Gemma.

However, it could go deeper.

LaRoche could be doing work for someone above him.

This could be someone in the Nexus cartel, the Department of Justice, or even Marino.

NCIS is a television series that follows a team of special agents from the Naval Criminal Investigative Service. Premiering in 2003, the show explores various cases involving Navy and Marine Corps personnel, ranging from murder and espionage to terrorism and stolen submarines.

In any case,McGee’s suspicions of LaRoche would prove to be correct.

LaRoche is actively betrayingNCISto serve a larger goal.

As a result, LaRoche’s potential blackmail case starts to make sense too.
