In "The Namesake", it is revealed that LJ Moore, a World War II veteran and Montford Point Marine, had influenced the teenaged Gibbs to join the Marines.
In Semper Fidelis Gibbs mentions that his grandfather had that it blew up once. In My Other Left Foot, Gibbs states that he had an aunt who died at age seven. 
Gibbs was, according to his father, such a happy child. When he was a kid, he had a dog who he loved very much. When dog got hit by a car, young Leroy become angry so he would lash out without thinking and getting into fights. After he saw this his father Jackson taught him fishing to “help him see straight”. 
After Jackson taught him to fish, he showed young Gibbs how to swing a hammer. His quote about woodworking was, "There's a lot in this world you can't make right. But the wood you can always make right, and that's a start."
When Gibbs was about 9 years old, his father helped him build his very first boat, named "Chickadee" after a nickname his father Jackson called his mother Ann. Her quote about building boats was "A boat named after a person will live forever." That's when he got his love of building boats and other things by hand with hand tools. Young Gibbs would spend all his time out in the garage working on some project, even though they didn't have electricity out there.
When he had been nine years old Gibbs he was become deeply upset that John Sydney, who was Gibbs' family friend and appeared to be he very close to, had left without a word.
At the age of 14 when his mother died of cancer, it was revealed that she had actually committed suicide so that her husband and son would not have to watch her suffer, leaving Jackson a widower and also forcing him to raise young Leroy all by himself. Unknown to younger Gibbs, Jackson blamed his best friend LJ Moore for her death as she had confided in him about what she was going to do and he had not stopped her, with this secret breaking apart their friendship and neither Gibbs nor his father seeing Moore again for many decades. 
After his mom Ann died, Gibbs not takes its very well, Jackson noted that made young Leroy very mad and he knows how much he hated Jackson for getting on with his life. Jackson saw the look in his son’s face, knowing how younger Gibbs wanted vengeance and he going to find someone to take it out on and it didn't matter what his father said. Following that, Leroy Gibbs started fishing more again.
As a teenager Gibbs faced confrontations with Chuck Winslow and Ed Gantry and he often provoked violence with defiance to his father, who constantly comes to his unwanted aid with his special Winchester rifle. He was also known around the area as a delinquent, as said by sheriff Gantry, one of the other delinquents during his teenage years, stating, "Funny, never expected to find you on the same side of the law".
He became captivated by local girl named Shannon Fielding, who he first saw in a window at the local clothing store “Ellen’s Dress Shop”, where she was dressing a mannequin in the window, who he would properly meet for the first time before being deployed. 
After graduating from high school, rather than going to college Gibbs chose to join the United States Marine Corps instead. Gibbs left Stillwater in 1973In “Heartland” he said summer 1976 and it was bicentennial, son his birthday in 1958. But later its revealed he born in November of 1954 and he enlisted when he was 18, so its possible he joined in 1973 and had little contact with the place for over thirty years. At the train station, Shannon asked why Leroy was fighting with Chuck and Ed and he said it over something stupid. Then she said, "You should probably stop that." and she asked Leroy for his name and he told her, "Leroy Jethro Gibbs." She looked at him with a smile and said, "I'm just gonna call you Gibbs", and he then said, “You can call me anything you want”, and after that, she then said, “I'm Shannon”. It is later revealed that Shannon inspired Gibbs to create his rules as she was creating her own set of rules to live by.
Later Gibbs shipped to Marine Corps Recruit Depot in Parris Island for recruit training, gaining the serial number 817657329 in which he added a G after to close friends. There he befriended fellow Marine PFC Joan Matteson, before Gibbs could really get to know her, Matteson along with several other Marines were killed in a helicopter crash on April 3 of next year, after she was deployed to Okinawa, Japan.
Later Leroy and Shannon started dating. And according to Jackson, that vengeful look on his face went away when he met Shannon, but it came back quick after his family died, but later Gibbs stated that never went away.
Gibbs's early years in the Marine Corps were with the Military Police in Camp Lejeune.
He rose to a Non-Commissioned Officer rank of Sergeant. As a Marine, Gibbs befriended Dwayne "King" Pride, Bushnell, Patrick Kiley, Charles T. Ellison and Kevin Maloney, people he would once encounter during his time as an NIS/NCIS agent.
In 1980 he being accepted to Scout Sniper School in Camp Pendleton. Later he briefly broke up with Shannon out of fear losing her because of his marine status via phone call. 
While going to buy/pick suit to going on wedding of his buddy in DC, he was abducted by Vito Zucado and had met Dr. Donald “Ducky” Mallard, after the latter accidentally saved him by crashing into Vito's car. After giving his story to NIS, he and Ducky, after 3 days of drinking together, were abducted by Vito's cousins and Jonny Zucado who beat Gibbs up until he knocked out a tooth. Thanks to Ducky, they were spared. After taking advice from Ducky, Gibbs go back to Stillwater and reconciled with Shannon. A few months later Gibbs became a Scout Sniper.
He and Shannon married in December of 1981. He get along with Shannon' parents, they was happy that Shannon married Jethro. On August 16, 1982, Leroy and Shannon had a daughter they named Kelly Gibbs. When Kelly was toddler, he get transferred to new base (presumably MCB Quantico), he have little confrontation with his mother-in-law Joann about that and later they moved too new place (presumably Virginia). 
Later after he bought a house in Virginia (previously owned/rented by Ducky in 1980), him and his family lived here until he get transferred to MCB Camp Pendleton, they followed him to lived with him in San Diego, California.
He rose from Sergeant to Gunnery Sergeant rank. He saw several overseas deployments. During 1989-1991, Gibbs was served on tour of duty in Panama (Operation Just Cause) and in the Persian Gulf (Operation Desert Storm) with the 1st Battalion 1st Marines. His Commanding Officer during Desert Storm was Lt. Col. William Ryan. And Leuitenant David Cameron died in Gibbs's arms during a battle after trying to save Gibbs' life.
In February 1991, Shannon witnessed the murder of a Marine by Mexican drug cartel leader Pedro Hernandez and agreed to testify against him, with her and their daughter Kelly being placed under the protection originally by NIS Special Agent Bernard "Randy" Randolf, but because his wife just had a baby, NIS Special Agent Kurt Mitchell took over for him. However, Mitchell was shot in the head by Hernandez while he was driving them and died instantly, both Shannon and Kelly died when the van crashed into a wall.
During his deployment in Desert Storm on last days of February, Gibbs received the news that both Shannon and Kelly had been murdered. Being understandably grief-stricken and devastated, he was wounded by walking during an engagement (committing suicide) and was left comatose, when he treated by Dr. Todd Gelfand. After that he evaded to Frankfurt for operation. From Frankfurt, he was air-lifted to Bethesda Naval Hospital. He was in a coma for nineteen days under Dr. Lin who watched over him until he woke up. Gibbs was an in-patient at Bethesda up until being discharged in least on June of 1991. As he had been wounded in combat with an enemy force, Gibbs was then awarded the Purple Heart medal.
After Gibbs gets back home in San Diego, he couldn’t get to his own house, because it was too hard to go inside ('cause memories of his deceased family). Following that he decided instead rent an apartment and he meet Ruth Orozco, his building manager. During that, Gibbs met NIS Special Agent Michael "Mike" Franks from NIS Camp Pendleton Field Office, who was alongside with his team (Randy and Lala) investigating the deaths Shannon and Kelly and showed him the van, where they and Mitchell was killed.
After seeing that and frustrated that Hernandez gotten away to Mexico, grieving Gibbs started drinking and getting into fights again. After that he started annoying NIS Camp Pendleton FO stuff (including Mary Jo Hayes) by continuously calling them, Franks confronted him, Gibbs accused Franks that he too scared lose his job or of Reynosa Cartel and after they started fighting. After Franks handled Gibbs, he collapsed to his arms and started confessing that he didn't want live anymore and is why/how he got wounded. And he can't live if Hernandez still is out there and get away with murdering his family.
Later when Gibbs visits Franks in the Pendleton Office, Mike decided he'd leave a file with information about Hernandez (after him saying that he was going to take a leak), 
Gibbs started investigating and he finds Pedro's location due to a photo in the newspaper that revealed Pedro's partial license plates in the photo. In July that year Gibbs travelled to Mexico and shot Hernandez in revenge with his sniper rifle over 1,200 feet away. He was shot in the head. Later Reynosa Cartel cover up Pedro's murder as him being alive/disappeared and not wanting them seen as "weak".
Following that, Gibbs decided left Corps, because he felt he don't deserve to wear the uniform anymore and he wish it did, but it doesn't. After that he calls his dad to tell about being discharged from Corps via voicemail, but after Jackson picked phone he lied about cleared for duty and he starts messing up his room. After that he been kick out of apartment for disturbing the peace for the 15th time by Ruth, Gibbs living in his truck for days and trying reach Franks (who was avoiding him), but Ruth taking him back with condition that he fixed all of damages and she approve 'em once they're done. And she also keeping his security deposit.
Later he gets befriended with Ruth over solving a jigsaw puzzles. One night she call out Gibbs, saying he need help, wash his hair and get job, because he no better than the homeless guys going through her garage. Following that night, couple of days later Gibbs started working as cashier at the grocery store. He got a lot of compliments from the customers because everything he learned at his dad's store was paying off. A week went by, Ruth started coming back over with the puzzles. They'd do a few hours at night when he got home from work. Once Ruth said to him that he looked like crap in his apron, but Gibbs pretty sure that she said that 'cause she knew that work not his purpose.
One day at store meet Mike Franks and his wife Tish, he trying talk about Mexico, but Mike avoiding conversation, while Tish trying convinced him to talk with Gibbs. After he tried to walk away from Gibbs (‘cause Gibbs not gonna let him off that easy and Mexico was too big to carry on his own), Mike told him that Gibbs not his problem, because he knows either Gibbs looking for intel that he ain't got or he want confess about killing Hernandez. He also advices Gibbs to find a new purpose, ‘cause he was too bright to be bagging groceries. 
After that shift, Gibbs and Ruth tried to chase her robbers, they ended up on beach and drinking beer. After Ruth reviled that she messed up her son’s life (who lives in New Orleans and he’s an architect) for a
whole lot of years and makes sense why he don't want to talk to her no more, Gibbs confesses to her he killed man who killed his family and now feels good to have somebody else know that. And apologising for he dump that on her and he understand if she don't want to come over to him anymore. After that little confusion Ruth told him what she saw in him: That he was a guy who managed to hunt down a killer that no one else could find and also that he was ready to chase down her robbers without thinking twice, that he paid attention, that he noticed what music she liked and cared about a bruise on her arm. And she said out loud what his gut had been telling him for weeks: that if he went all in, if he got himself together, he could make a pretty good cop.
In August of 1991 Gibbs wanted joined the NIS, presumably having been impressed and inspired by Franks' actions and Gibbs went over to the NIS Twentynine Palms Field Office. But being a Marine helped him get approved quickly and they said to him that he be a their probationary agent when he graduated from Federal Law Enforcement Training Centre (FLETC). Gibbs was in Glynco, Georgia for the next two months. FLETC's physical training was easy to him, after Scout Sniper School and deployments (including Desert Storm). But his problem was that his head still wasn't right.
He thought maybe its bit off more than him could chew, but Ruth said otherwise, "The comeback's always stronger than the setback." And sometimes, she'd add a few other words of encouragement. Ruth's letters meant everything to Gibbs, she became big sister to him. 
Later Gibbs was graduated from FLETC with being top of his class. After graduation, he rushed to get home and prove Ruth that she was right about him. After she congrats him, Gibbs noticed another bruise, she confessed about having blood cancer. Later he has an appointment over at NIS for psychological evaluation. After failing his psych eval and psychologist didn't have to say it to him, but Gibbs seen that it’s was all over his face. Evaluation stated that he is in a depressive state, because of trauma, have impulsive tendencies and unaddressed anger issues. And evaluator strongly recommended him extensive therapy and concluded he wouldn't succeed long-term at NIS.
Following that Gibbs got to Daly's Tavern and he calls Ruth to asking why she hiding her illness from him. She told that helping him to become the man he were meant to be is the only good thing she ever done. Then he tell her that he failed psych eval and he is sorry to let her down. After hung up phone he having confrontation with Marines, Gibbs started fighting them. All of them was arrested and he getting relised/processed out to Ruth. Unknown to Gibbs, Franks also was here cause he got a call from Smitty, Ruth confronted him how he was abandoned Gibbs and Gibbs thinks Franks’s great, ‘cause he's the whole reason Gibbs picked NIS. After that Franks decided hired Gibbs with approval from SAC Cliff Wheeler and informed his team about their new team member.
Later after hearing from SAC of Twentynine Palms said that they're pulling their job offer, Gibbs once again start fighting at Daly’s. After fight was stopped by MP and being reported, Franks come over and says that he passed his psych eval and now Gibbs working for him. He got to go to Camp Pendleton Office on tomorrow morning in 0800 and meet an agent Randolph. For years, Gibbs couldn't understand why Franks hired him. But one day over beers, Mike told him about his talk with Ruth and Gibbs wasn't surprised she got in Mike’s head.
On morning of his first day of work he heard Kelly laughing and saw Shannon's face, it’s was enough to him want to crawl back in bed. But then he heard Ruth’s voice in his head saying, "Leroy, get up and go to work."
In October of 1991, Gibbs becomes a member of Frank's team and meets Special Agent Cecilia ”Lala” Dominguez, Special Agent Bernard "Randy" Randolph, Special Agent Vera Strickland, FOSO Mary Jo Hayes, and SAC Cliff Wheeler. He subsequently became Temporary Special Agent in Camp Pendleton Field Office.

==Personality==
A man of few words, Gibbs is known for his glare which can have others, whether it be his fellow NCIS colleagues or criminals talking in seconds or shutting up immediately. He is a gruff man who speaks his mind and has a dislike towards political red tape as well as politics and lawyers. He comes of as strict and as a person with no humor, but he is still a person everyone respects and looks up too. He hates waste of time and is a very impatient person. He cares deeply for other people, and find his work to be extremely important. Gibbs is not good at talking about emotions or showing feelings, but he does care for all of his team members and have a different dynamic with all of them. He is describes by DiNozzo to be a functional mute, as often his silence is a language in itself. He is very protective of the people he loves and will break the rules to protect them. He is extremely intelligent, often seeing solutions and cracking the case before anyone else does. He is also described as fearless. 
He is also known for his head slaps who he got from Special Agent Michael Franks. As well as always finding out secrets and standing behind people when they talk about him. 
His relationship with modern technology is vitriolic, to say at least. He smashed a smartphone McGee gave him and threw an iPhone that Phil gave him to a fireplace and he always prefers a flip phone, seemingly refusing to give it up. He stomped a Roomba to pieces, is unfamiliar with websites and social media or how they work, and shot a computer. In some episodes, he also doesn't keep up with modern times, as revealed in one episode that he had no clue who the Kardashians are. He loves his coffee and have a serious addiction to caffeine. His days are often ruined unless he gets his morning coffee. 
Not long after Tony's and Abby's departure from the team, Gibbs began facing strong emotional situations from current and past events, getting closure to moments he kept hidden as far back as when he was a child. He began to open up a bit more to those around him and began expressing himself more once he started to overcome some of these events. 
==Physical Appearance==
Gibbs is a tall man in his late fifties, early sixties with silver/white hair and blue eyes.
For work, he usually wears a causal suit that consists of either a polo shirt or a button up shirt, a blazer jacket (usually a solid color), pair of slacks, and dress shoes; for outside of work, mostly an old-school button-up shirt (mostly flannel/plaid) with a t-shirt under it or a hoodie USMC (United State Marine Corps) sweater, either denim jeans or cargo pants, and sneakers.
==Abilities==
As a former Marine, he has the ability to fire a sniper from over 1000 feet away and still hitting his target (As shown in flashback episodes when he killed former Drug Cartel Leader Pedro Hernandez). As a former NCIS Special Agent, Gibbs usually showed his ability of being able to catch the bad guy when they run by taking short cuts and being a few steps ahead of them. Therefore, they end up giving themselves up to him. He also carried his SIG and rarely missed his target. He has more unique range of abilities, many of which have made him a great asset to the NCIS Agency. 
===Hand to Hand Combat===
During his time in the Marines, Gibbs presumably learnt how to fight and is an exceptionally skilled fighter, able to subdue opponents. This had helped him in the long run when chasing or fighting the bad guys.
===Intelligence===
He is extremely intelligent, often seeing solutions and cracking the case before anyone else does. 
===Knives===
Gibbs always followed Rule number 9, "Never go anywhere without a knife." This skill with knives had helped in several occasions. 
===Firearms===
Gibbs is impeccable when it comes to firearms. He is a former Marine and was trained in sniper training and can shoot his target over 1000 ft. away. 
===Medical Training===
He had some medical training that he learned from the Marines. This came in handy when he helped Marine Lieutenant Emma Reynolds give birth in the back of the NCIS car at a garage in the Newborn King (episode). 
===Interrogation===
He is a very skilled interrogator. His method of speaking to suspects was often described by Tony and McGee as suspects willingly confessing through tears than wanting to face Gibbs, Tony once mentioning to Penelope Langston that even Atila the Hun couldn't face Gibbs.

They were on their way to a safe house when Hernandez shot and killed Agent Mitchell killing him instantly. Kelly and Shannon were killed when their van crashed into a wall. At this time, Gibbs was enlisted and fighting in Desert Storm. Shannon identified Hernandez as the killer working Camp Pendleton.
Gibbs is shown to have deeply loved Shannon and treated her very well. When learning of her and Kelly's death, Gibbs fell into a state where he could not be happy. He was so angry, he wanted to get revenge. He did so, by killing Pedro Hernandez 4 months after Shannon and Kelly died. He was located outside of a drug cartel Reynosa Cartel and was leaving when Gibbs shot and killed him from 1000 yards away.

She knew Gibbs just married her to get over Shannon. She also took her huge alimony from the divorce and Gibbs' grandfather's watch. Gibbs mentions several times that she cleared him out after their divorce. As potentially the fiercest natured woman he was married to, Gibbs tried to keep his distance from her as he often did not want to deal with her angry way of handling things and inserting herself into his work.

They became friends after she became Director of NCIS replacing Thomas Morrow.

Although he understood her reason and allowed her numerous chances to confess to her actions.
*Leroy Jethro Moore - Leroy Jethro "L.J." Moore was Jackson's best friend and co-owner of their General Store when they were younger. L.J. was confided in by Ann (Gibbs' mother) when she said she was going to commit suicide because she was dying of cancer. When Jackson found out the truth, it put a major strain on their relationship and they stopped talking for over 15 years. Near the end of the season, Jackson and L.J. mended their relationship and became friends again.
*John Sydney - A man Gibbs knew in his childhood and appeared to be very close to, possibly seeing him as a close family member. During The Last Link (episode), Gibbs was shown to somewhat avoid Sydney until forced to return to Stillwater on a mission to find a missing medical bracelet as Sydney needed to fulfill a vow he an other men from Stillwater made. During that time, Gibbs revealed that he was deeply upset that Sydney had left without a word when he had been nine years old but came to understand why when learning the story behind Sydney's sudden departure.

Even though Gibbs is a hard man to get to know and they are very different individuals, the two of them are very close and considers each other to be family. They also respect and protects one another and value each other's advice and opinions. They grew even closer when Dr. Mallard had his heart attack.
*Tobias Fornell - He has formed a rather brotherly bond with Tobias over the years, due to both being divorced by Diane. Gibbs calls the man by his first name on a regular basis and earning himself the title of Uncle Gibbs to Emily Fornell.

Fornell often drop buy Gibbs' basement and have a talk. The pair were very close, Tobias even hinting at one point that he was aware of Gibbs having killed Hernandez back in 1991. At one point when Gibbs is pushing him away emotionally—out of guilt—Tobias tells his friend, “Gibbs, this is me! This is me. You do this to other people; not to me." Tobias is the main reason why then FBI Agent Alden Parker decided to let Gibbs go in Season 19. As Parker would put it, "Let's just say he convinced me that you don't belong behind bars."
Colleagues:
*Leon Vance - Leon Vance was hired on as the new Director of NCIS by SECNAV (Secretary of the Navy) after Jenny Shepard was killed in the season 5 finale. He and Gibbs sometimes butt heads when it came to certain protocols and criminals. It took them both a long time to trust one another and they are not close, but they have a working relationship that gets things done.

Leon and Vance became closer when Gibbs' team investigated the death of Leon's wife Jackie Vance and the Director of Mossad and Ziva's father Eli David. 
*Stanley Burley - Stan Burley worked together with Gibbs at NCIS before being transferred out to another location. He revealed to Tony that it was two years before Gibbs would even look Stan in the eyes and another 4 years before he got his name right.
*Anthony "Tony" DiNozzo - Even though they are very different individuals they have built up trust towards each other. Gibbs is often annoyed with DiNozzo's no stop chatting and movie referrals, but at the same time appreciates the fun and more juvenile vibe he brings into the team. Tony has massive respect for Gibbs and trust him 100% and is always the most loyal to Gibbs out of all the other team members. In Season 7, Episode 12 Flesh and Blood when Gibbs first met Tony's father he gets "defensive" over Tony. Gibbs also questions Tony's father about his relationship with his son and is vocal about his disappointment over that he does not know his son as a grown man. He stands up for Tony as an individual and calls him "one of the finest young agents he has ever worked with. In Tony’s last scene of NCIS, he tells Gibbs, “I would say thank you, but I don’t think it quite cut it.” The relationship Tony has with Gibbs is one of a special kind.
*Abigail "Abby" Sciuto - The relationship with Gibbs and Abby is one of a kind. Gibbs treats Abby like his daughter and loves surprising her. He would take her out for dinner the evening before her birthday every year and using her first language—American Sign Language—with her on many occasions. He has massive respect for her, and she is definitely the one person at NCIS he is the most patient with. He buys her Caf-pow almost every day, while he rarely buys anything for the other team members.
*Caitlin "Kate" Todd - Jethro and Kate were also like father and daughter. They first met when Kate was a Secret Service Agent. Kate ended up getting killed in the Season 2 finale when the man they were hunting (Ari Haswari) shot Caitlin in the head with a sniper rifle. It is visible that Gibbs had respect for her as an agent and that the respect was mutual.
*Timothy "Tim" McGee - Although he never really understood McGee's technical language, Gibbs trusted McGee greatly when it came to computers. At the same time, he knew McGee well and knew that he potentially could not lie to others so he would work things so that McGee's confessions were true while keeping him in as less trouble as possible.
*Ziva David - Ziva saved his life early in season 3 and it is mentioned by Ducky that she was the team member he started trusting the soonest. He calls her "Zivers" and has stuck his neck out for her many times, when her loyalties have been questioned. He respects her skills and she views him as a father figure.
*Eleanor Bishop -

==Trivia==
*Most people refer to him as Gibbs, but there are a few exceptions. His father, Jackson Gibbs, his ex-wife Diane Sterling, and his namesake, Leroy Jethro Moore, called him Leroy. Shannon Gibbs, Donald Mallard, Jennifer Shepard, and a few others used Jethro instead. 
**Interestingly, Abigail Sciuto, the former NCIS Chief Forensic Specialist, consistently called him Gibbs despite the obvious close relationship between the two. In contrast, he would call her both "Abby" and "Abbs".
*He, Timothy McGee, Jimmy Palmer and Donald Mallard are the only main characters to have met every other main character in the mothership.
*There have been a few inconsistencies in his age/birthdate and when joined Marine Corps:
**In “Heartland” Gibbs makes reference to the fact that when he joined the Marines the country was celebrating the bicentennial (1975-1976). Assuming Gibbs joined when he was 18 years old, it's likely that Gibbs was born in 1958.
**In “Date with Destiny” Gibbs's year of birth, as shown already carved on his family headstone is 1954.
**In NCIS ep. “House Divided” his ID shown he was born on November 21, 1954, making his age at the time of JAG 2-part backdoor pilot/the first episode 48 years old.
**In NCIS: Origins ep. “Enter Sandman” Gibbs said he joined Corps at 18 and his birthdate on NIS’ temporary agent credentials (November 21, 1954) in 1991, presumably it’s was in 1972 or 1973.
*He knows American Sign Language (ASL).
*Gibbs's address is shown as "500 Block East Laurel St, Alexandria, VA" The address does not exist so Google Maps returns Laurel Rd, Alexandria, VA. Laurel Road ends at Gibbs Street.
*He used to never lock the front door to his house because he has already lost what was most important to him, and everything else can be replaced.
*After Margaret Allison Hart shows up in his house in season 7 episode 14 masquerade saying he doesn't lock his door, he gets a new lock which McGee notes in the beginning of season 7 ep 15 jack-knife.
*In season 15 he was seen both locking and unlocking his front door, even going so far as to give Jacqueline Sloane his keys in Skeleton Crew and telling her to lock the door when she leaves after having just met her. 
*In the fourth episode of season 19, Great Wide Open, the mystery of how Gibbs got the boats out of his basement was finally revealed. It turns out he would break the basement wall to get them out and then rebuild the wall. However, it was alluded to much earlier in season 5 episode 14 Internal affairs McGee asks how he gets the boat out and Gibbs responds with "just break the bottle" a clear reference to a ship in a bottle alluding to the fact that he would break the wall down.
