Guns can keep the peace, but they can also take lives.

Tonight’sNCISepisode tackles that duality as the team tries to solve the murder of a gentle giant named Peacekeeper.

Victor’s universally described as a kind man who worked a number of part-time jobs.

Even his ex-wife Lexi has good things to say.

Also of note is one of the guests at Lexi’s gun show-and-tell.

Palmer suggests Gibbs would tell her to keep her options open while she’s taking the time to heal.

As for Palmer, he’s pulled too many bullets from bodies over the years to own a gun.

Hey, is Kasie in therapy?

Because Kasie should be talking to someone about all this.

Back on the case, the team visit the Fairfax Expo Center, where Victor worked security.

Is Knight in therapy?

Palmer’s patience pays off when he finds three bullets not linked to firing range guns.

Plus there are lots of people he’d rather not own one.

(Same, sir.)

They had a few drinks at closing and fought about the night’s take being short $300.

One thing led to another, and Harry brandished his new gun, which went off.

The next morning, he found the missing cash under his desk.

It’s a sad story, and another example of a guy Parker wishes hadn’t owned a gun.

The episode ends with Knight taking Kasie to a shooting range, patiently talking her through the process.

It’s interesting to see the state of Kasie and Knight’s friendship.

Although Knight’s still quite new, the women seem close.
