McGee Finds Out ‘The Truth’ From LaRoche

In the NCIS Season 22 finale episode, Tim McGee and Gabriel LaRoche face off. All season, McGee was circling around LaRoche like a boxer waiting to take a big punch. However, in the preview video, the guy that got McGee’s job is ready to tell him the “truth.” Has McGee been wrong about LaRoche? Or could there be a few new twists that McGee did not see coming? The team is about to find out that the team has been in the dark about some nefarious activities. Moreover, could this bigger story become a part of Season 23?

Next the agents and some bad actors surround each other with guns locked and loaded. Alden says “bomb,” and it is clear that this is more than a gunfight. There is something major going down. Lastly, Jimmy tries to figure out what happened. Was LaRoche shot, or someone else? Then, the agents are flying all over the place with guns aimed. What is happening?

According to TV Insider, this isn’t just any bomb they are talking about. This is a nuclear bomb. Will Parker compromise his integrity to stop the thieves from stealing nuclear material? But what he does could compromise the team and his future. Is Parker willing to work with the mob and take that sort of a risk? Who could pay for Parker’s risky decision?
