Everything Gibbs Doesn't Want You To Know About Him

We all know Leroy Jethro Gibbs, but do we really know Leroy Jethro Gibbs?

He's tight-lipped about his past, but we've managed to learn a thing or two about the man over his years on NCIS. We culled our records to create this dossier about Gibbs. He might not seem eager to let people into his world, but when we put it all together, it's clear why we've grown to love him so much.

Despite their tumultuous relationship, Gibbs will always hold a special place in his heart for his father, Jackson Gibbs. The former Army Air Forces pilot raised a young Gibbs in Stillwater, Pennsylvania, after his wife passed away. 

You might think Gibbs is far too busy to concern himself with fashion, but, then again, you might be surprised! Ever notice how he's always wearing a white crew-neck T-shirt? It pops out from under his polo or collared button-down and sport coat. He's got a reason for the layered style. 

According to Rachel Good of the NCIS costume department, the white undershirt is indeed a staple in Gibbs's closet. It represents his time in the Marines. Good also revealed that Gibbs got the polo and coat inspiration from retired NCIS Special Agent Riley McCallister.

Gibbs met his first wife, Shannon, at a train station in Stillwater. Shannon lived her life by a code, which eventually inspired Gibbs to create his own set of rules. The two later married and had a daughter, Kelly, whom they adored. Unfortunately, the family's happiness didn't have an opportunity to last long. 

After Shannon witnessed cartel member Pedro Hernandez murder a Marine, both Kelly and she were placed under protective custody. One night, Shannon and Kelly were being driven by an NCIS agent responsible for looking after them. A vengeful cartel member tracked them down and shot the agent in the head. With no one to take control of the wheel, the vehicle crashed, and both mother and daughter died instantly.

While it wasn't his fault, Gibbs has always blamed himself for serving overseas instead of protecting his family.

Years after Shannon and Kelly died, Gibbs was ready to put himself back out into the dating world. He met a fiery redhead named Diane, and the two seemed to hit it off. It wasn't long, however, until the two got a divorce. 

Diane, who once said she was simply Gibbs's "human antidepressant," later went on to marry FBI Senior Agent Tobias Fornell, despite Gibbs's numerous warnings. Fornell later wished he'd listened to Gibbs's advice after Diane cleaned out his bank account. 

After dealing with the fallout from his relationship with Diane, Gibbs married a woman named Rebecca Chase. Their marriage didn't last long, but the two would occasionally cross paths. As part of her alcoholic recovery program, Rebecca made an effort to mend her relationship with Gibbs and to let him know she was marrying her divorce attorney. 

During a crime investigation, Gibbs was shocked to learn his two ex-wives, Rebecca and Diane, knew each other. Coincidence? He thought not!

After one tragedy and two failed marriages, Gibbs was still hopeful that he could make it to the end with someone. He married a woman named Stephanie Flynn, and the couple spent a lot of time in Moscow while Gibbs worked. Sadly, Gibbs and Stephanie split after only 14 short months. 

While Gibbs hasn't shown interest in remarrying, he hasn't completely taken himself off the market. Some of the notable women he's dated include former NCIS Director Jenny Shepard, medical center Supervisor Karen Wilkerson, Lieutenant Colonel Hollis Mann, and the Pentagon's Dr. Samantha Ryan. 

One thing's for certain: He's interested in some seriously smart women!
