Abigail "Abby" Sciuto is the Chief Forensic Scientist for the NCIS Major Case Response Team.
Born in New Orleans, Louisiana, Abby was later given up for adoption by her birth parents and taken in by an unnamed family who later raised her as their own along with their son, Luca Sciuto.
During her childhood, Abby was raised all over the southern United States and apparently learnt to drive a manual transmission when she was ten years old which was revealed in the Season 3 episode, Kill Ari Part 2 (episode).
Her parents, presumably her adopted parents were or are deaf which is why Abby enjoys listening to her music at loud volumes as noted in the Season 1 episode, My Other Left Foot (episode) and the Season 10 episode, Phoenix (episode) and also due to the fact that her parents are deaf, Abby is skilled in American Sign Language and also possess the ability to lip-read.
Upon finishing high school, Abby later went to college, graduating with full honors from Louisiana State University with a triple major in sociology, criminology and psychology. She also earned her master's degree from Georgia State University in criminology and forensic science.
At some point, Abby later joined NCIS and has remained with the agency to this day.
JAG Season 8
She was seen in her lab, drinking some Caf-Pow watching two other scientists conduct a test on a dummy wearing a sailor's uniform when Tony arrived in with some evidence and after the two had flirted while discussing the paintings Abby had on the walls of her lab including one of a shotgun-shattered backbone and another of a cross section of an ice pick to a cerebellum with Abby calling the painting "The Sad End of A Drano Drinker".
After she had finished flirting with Tony, Abby then began working. She later called the team down to her lab to discuss her findings where she determined that the victim, Lieutenant Loren Singer with Gibbs telling her "Good job" although Tony mistakenly believed that the compliment was for him. She then told the team that Singer's stomach contents which was peanuts, pretzels and crackers were part of a bar mix which also revealed to the team that Singer had been at a bar on Falls Church called Benzinger's.
Abby was later seen in the NCIS Evidence Garage getting fingerprints from the dashboard of Singer's car with Tony promising to bring her to Cafe Atlantico if she got him an ID within two hours instead of the usual twelve with Abby remarking, "Sweet".
She also arrived into Observation during Gibbs's interrogation of JAG lawyer, Commander Harmon Rabb to inform Tony and Viv that Rabb's fingerprints had been found all over Singer's car.
In Meltdown (episode), Abby continued working on the case and even formed a friendship with lawyer Major Jack McBurney although she was left shocked when McBurney informed her that she would have to testify in regards to the murder case which left Abby stunned and also terrified as she admitted that she hated testifying in front of those military types.
Abby later testified in the case against Rabb where both Major McBurney and Lieutenant Commander Faith Coleman questioned Abby in regard to the findings she had uncovered while processing the forensic evidence associated with the Lieutenant Loren Singer murder case.
Once she had finished, Abby returned to NCIS where she resumed her work before calling McBurney much to Gibbs's obvious disapproval.
Once the two lawyers had left, Gibbs said "Good job" to Abby which she thanked him for but Gibbs then grimly informed her that she shouldn't go calling lawyers before stating that she ought to call him next time instead which burst Abby's bubble and left her unusually stunned.
After recovering from the tongue-lashing, Abby's final appearance in the JAG episodes came when after running some tests, she eventually summoned Tony and Viv to her lab where she told them that the hat that Dobbs had eventually found was nothing more than a plant which confirmed Tony's theory that Commander Harmon Rabb was not the killer and that the real killer was still out there.
NCIS Season 1
Abby made her first official appearance in the NCIS Season 1 premiere episode, Yankee White (episode) where she was seen using an ALS- Alternative Light Sources to examine the uniform of a Navy Commander who had died while having lunch with the President of the United States on board Air Force One.
She later ran several more tests before it was determined that the poison used to kill both the Commander and a Major had come from a Coastal Taipan, a deadly snake found in Australia before she and Ducky informed Gibbs of this statement during a joint-conference call to Gibbs who was on Air Force One at the time.
In Hung Out to Dry (episode), Abby was seen changing the paintings on the wall in her lab much to Tony's dismay before Gibbs and new NCIS Special Agent Caitlin Todd arrived, seeking answers in regards to a case that they were working on that concerned a Marine who had presumably died from a faulty parachute.
Abby and Kate later worked together to investigate dissolved lines that were from parachutes that NCIS had confiscated and later told Gibbs and Tony of their findings.
Abby later obtained a DNA sample from Corporal Dave Ramsey which had her later remarking that the Corporal's mouth was drier than mummy dust and that she needed 24 hours for the testing process to go smoothly.
Abby brought the team down to her lab where she told them that she had discovered some traces of cocaine on the sabotaged shroud lines of the parachute that the victim wore before his death. She also helped the team uncover the reverse chute which Gibbs later discovered had been tampered with.
In Seadog (episode), it was revealed Abby knew sign language which she used during a talk with Gibbs and she also told him that the single round that had killed Commander Brian Farrell was also responsible for the deaths of two drug dealers.
She also later revealed that she had found traces of C4 on a boat that some terrorists had used.
In The Immortals (episode), Abby displayed some knowledge about MMORPG (Massive multi-player online role playing games) and began playing "The Immortals" in the hope of finding some clues into the investigation of the death of Seaman Russell MacDonald.
She later contacted Gibbs, revealing that someone else assigned to the Foster also played the game as well.
In The Curse (episode), it was shown that Abby believes in curses.
NCIS Season 2
In the Season 2 episode, Vanished (episode), it was revealed that Abby had a fascination with the paranormal and also crop-circles.
Also, despite not having any field training, Abby went undercover at a place called Scarlet Secret in the Season 2 episode, Forced Entry (episode) to gain access to the servers to help the team find the person responsible for the death of hacker Victor Grotinski.
NCIS Season 3
Like the rest of the team, Abby was left devastated and grief-stricken after Kate's death at Ari's hands.
In Kill Ari Part 1 (episode), the Season 3 premiere episode, Abby was seen in her lab, glancing at a photo of herself as a vampire bat, one Kate had created. While there, Ghost Kate, wearing Gothic clothing consisting of a pink wig, a long black dress and even a gothic-styled ring appeared before stating that Abby needed lipstick and that Abby should also put her hair up in pigtails.
NCIS Season 4
In Witch Hunt (episode), Abby wore an exact copy of the well-known dress that actress Marilyn Monroe had worn during the film "Seven Year Itch". To make her costume more realistic, Abby even wore a blonde wig complete with earrings while also painting her nails red and she had high-heeled white shoes as well. The costume she wore had her former boyfriend/lover, Special Agent Timothy McGee, and Abby's colleague DiNozzo stunned and only a head slap from Leroy Jethro Gibbs managed to get the two going again.
In Sandblast (episode), Abby revealed that she can also lip-read.
In Cover Story (episode), Abby also revealed that she's skilled at bartending, having once worked at the weekends in a bar that her Uncle Teddy owned.
NCIS Season 5
In Judgment Day Part 2 (episode), Abby was left shocked after learning of Jenny's death from Ducky.
NCIS Season 6
In Toxic (episode), after visiting the dentist, Abby was briefly attached to a top-secret government project that was code-named Tarburst ostensibly to fill the gap left by the project's chief scientist, Dr. Phillip Heller who had gone missing under mysterious circumstances.
Tarburst's stated goal was to cure Afghanistan War Syndrome, but was later revealed to be aimed at developing biological weapons that could be used to perform assassinations of any kind without even exposing soldiers or other assets to life-threatening or dangerous situations.
Upon learning the truth, Abby, furious at how she had been manipulated into creating a biological weapon, eventually quit the project for good and returned to NCIS where she helped the team solve the case, arresting the true criminal responsible.
Afterwards, she lured McGee, DiNozzo, and Palmer to her lab under the guise of Gibbs so that they could clean it, which the three men had rather carelessly ruined during their attempts to fill in for her while she was off working on the project.
In Legend Part 1 (episode), Abby was contacted by Lara Macy, the agent in charge of the NCIS Office of Special Projects in Los Angeles with Macy requesting that Abby's findings be forwarded to her first.
NCIS Season 7
In Borderland (episode), Abby was summoned to Mexico at the request of Mexican Department official Alejandro Rivera with McGee coming along as her bodyguard. She gave a lecture to various Mexican students and along with McGee, took the class out into the field where the group met Paloma Reynosa, the leader of the Reynosa drug cartel and also Alejandro's sister who informed the students, Abby and McGee of the crime that Gibbs had committed some twenty years ago which had resulted in the death of Paloma's father.
Paloma later gave Abby the bullet that had been used in the crime before she and her men left.
The next morning, having slept in the main study room, Abby produced the bullet and later logged onto the NCIS Database where she got a huge shock upon learning that the crime she had been assigned to investigate concerned Gibbs, his first wife and their young daughter.
Upon returning to the US, Abby acted unusually silent and distant as the team handled the case of a Marine who had been crushed at a junkyard.
In Patriot Down (episode), Abby kept dropping hints about what she'd learnt, only for Gibbs to constantly ignore her. Abby eventually lost patience and used a remote to shut all the doors in her lab so that she and Gibbs could talk with Abby expressing her hurt and frustration over Gibbs's refusal to talk about his involvement in Hernandez's murder.
In the Season 7 finale episode, Rule Fifty-One (episode), Abby discovered that bullets taken from Bell's remains belonged to Gibbs's SIG-Sauer although the evidence later revealed someone was trying to frame Gibbs for Bell's murder.
NCIS: Los Angeles Season 1
- "This place is seriously cool."
- —Abby after arriving into the Ops Centre in the OSP Building in the NCIS: Los Angeles Season 1 episode, "Random on Purpose".
Despite having developed a phobia of Los Angeles after Director Jennifer Shepard's death at an abandoned diner in California, Abby later went to Los Angeles to aid the Office of Special Projects team in capturing a serial killer ("Random On Purpose") who had murdered a Naval Commander despite many local law enforcement agencies including NCIS believing that the supposed killer who Abby had nicknamed "The Phantom" not even existing.
While in OSP, Abby formed friendships with the agents assigned to the main OSP team but her first-ever trip to Los Angeles and The Office of Special Projects Building also proved to be her last as the murderer who was later deemed to be real kidnapped Abby, intending to kill her.
Following that incident, Abby has not returned to LA to aid the team with any further cases nor has she had contact of any kind with the Los Angeles team, including her friend, Eric Beale since that incident which could be due to Gibbs's unwillingness to let her go back to LA alone given possible security concerns as well as his worries about the possibility that she might be kidnapped and held hostage again.
As such, Abby has not appeared in any recent NCIS: Los Angeles episodes and it's possible that her appearance in the first Season was just a one-off.
NCIS Season 8
NCIS Season 9
When the NCIS building came under attack from Harper Dearing in the Season 9 finale episode, Till Death Do Us Part (episode), Abby was seen grabbing her bag and Burt while attempting to flee the lab as well as a Caf-Pow but thanks to Gibbs tackling her to the ground just as the windows in the lab shattered from the intense explosion, they both emerged without any injuries.
In Enemy on the Hill (episode), Abby discovered that she had been adopted as a child and that her supposed biological parents were not her real parents. She also ran a test of some hair on the locket of her mother and later learnt that it didn't match, meaning that they were not related.
NCIS Season 10
However, in Recovery (episode), due to the attack, Abby's nightmares about being in the morgue which she beat in Bête Noire (episode) and which were presumably suppressed for nine or ten years have re-emerged with a vengeance, leaving her psychologically and emotionally traumatized.
NCIS Season 11
NCIS Season 12
Abby is a woman in her mid twenties or early thirties with long black hair and green eyes.
She wears Gothic clothing and also has her hair tied usually tied up in pigtails although she has been seen it with her hair down and she also ties it up in buns if she's attending church.
She expresses a strong disapproval of wearing "normal" clothing, often referring to such things as "monkey suits" and almost had a break-down when she was forced to dress in business casual in accordance to the NCIS dress codes that new Director Jenny Shepard had approved in Silver War (episode).
In recent years, starting with Season Eight's Spider and the Fly (episode), Abby was seen wearing tiny yet visible earrings in her ears and although they have since disappeared, she's been seen with a single piercing on her left or right ear.
As of NCIS Season 12, Abby has also started wearing black nail polish as well.
As a Forensic Scientist, Abby is skilled at processing evidence.
She is also extremely talented at hacking with her skills even matching those of her former boyfriend, NCIS Special Agent Tim McGee and also NCIS Tech Operators Eric Beale and Nell Jones.
As a Forensic Scientist, Abby is skilled at going through any and all kinds of evidence that the NCIS team bring to her in order to get clues into a possible suspect or a lead that will help the team with their investigation.
Another of Abby's skills is hacking which means that she is able to gain access to any database by any means necessary with Abby often doing this by herself.
Despite her Gothic appearance, Abby is caring and fiercely loyal to the team.
She is also happy and friendly with a habit of giving hugs to her close friends or colleagues. She has often displayed fear or nervousness if the team are in any kind of danger.
Relationships with Colleagues
Leroy Jethro Gibbs
- "What do you got, Abbs?."
- —Gibbs upon entering Abby's lab to ask her for information on the team's current case.
Some fans think Abby has a father-daughter type relationship with Gibbs. There is a running gag between the two when Leroy Jethro Gibbs walks in just as Abby discovers something, which she theorizes has to do with a psychic link. She is usually excited when Gibbs comes into the lab, especially if he has a "Caf-Pow," an extra caffeinated beverage Gibbs apparently gets her when he is refilling his coffee. He gives them to her as a reward for good work or as a "bribe", but threatens to take them back if Abby hasn't found enough evidence for him.
Abby is also one the few people Gibbs will allow to work on his boats other than children, not shouting at her when damaging it in the episode "Bloodbath" due to the fact that she was drunk at the time.
In the season 5 episode, "Leap of Faith", Abby receives a bouquet of black roses from Gibbs for solving the case. While Tony remarks that the flowers should have been his, McGee and Ziva both agree that Tony should stop trying because “Abby will always be Gibbs's favorite.” Gibbs takes her out to dinner the night before her birthday annually. These examples could also support the alternative view that there is an undertone of romantic interest between the two, as discussed below. However, Pauley Perette stated in her interview on Australian television show Good News Week, she believes "Gibbs is like a father figure to her (Abby)".
Other viewers believe that she and Gibbs could have romantic feelings for one another, hence the pairing Gabby. This view is based on the following evidence: First, one Valentines Day, Gibbs gave her a Caf-Pow with a stuffed "love you" on the straw. Second, Abby is extremely defensive against any accusation, joking or not, against Gibbs. In response to one such occasion, she declared that she can kill a person without leaving any forensic evidence. Third, in the season 5 episode, Leap of Faith, Abby receives a bouquet of black roses from Gibbs for solving the case. Fourth, Gibbs takes her out to dinner the night before her birthday every year. He once managed to sneak a gift into her office unseen even though she had been in the lab the entire night. While the rest of the team each gave her black roses, when she opened the large, gift wrapped box from Gibbs, it emitted a glowing light and she was impressed.
Also, Abby admitted in the Season 3 episode, Mind Games (episode) that "something about his silver hair gets me all tingly inside". Tony who had just come into the lab at the time reacted by saying, "Excuse me for a second. I think I'm gonna vomit". Seconds later, Abby reassured him that she was joking except for the bit about Gibbs's hair because she found that really hot.
- "I really liked you, Kate. A lot."
- —Abby talking to Kate's ghost in Kill Ari Part 1.
Upon joining NCIS, Kate and Abby became close, immediately forming a strong, budding friendship with one another due to the fact that at the time they were the only women on the team.
This first began in the Season 1 episode, Hung Out to Dry (episode), where after the two women had worked on a parachute's shrouded line, Kate, the newest addition to Gibbs's team, began talking to Abby about how she'd gotten into Forensic Science and from that moment on, the two struck up a friendship.
The two girls shared weekend vacations and frequent personal information. They often hung together and regularly mocked and teased Tony much to his dismay, solely due to the fact he always wanted to know what they were doing.
As seen in the episode, A Weak Link (episode), Abby confided in Kate about her current relationship with Tim McGee and Kate gave very helpful advice although for the duration of that episode, McGee and Abby were very frosty towards one another.
Like the others, Abby was left devastated by Kate's death, and as a result was initially cold towards Ziva, whose half-brother, Ari, had been responsible.
When Abby imagined herself talking to Kate after her death in the Season 3 premiere episode, Kill Ari Part 1 (episode), it was revealed that Abby had convinced Kate to get a tattoo. Abby's afterlife vision also showed Kate's ghost as a goth with white hair, telling Abby to put on her black lipstick while Abby looked at the picture that Kate had drawn of her. Abby kept that drawing of herself as a vampire bat that Kate had made for her on her desk.
Looking back on the friendship between Kate and Abby, they acted more like sisters, although Kate was the girlie girl and Abby was the metal goth.
Though Ziva David is tough, Abby treats her like a close friend. The two got into a slapping fight in "Hiatus Part One" but they made up thanks to Tony's efforts, although when he asked them to kiss each other, they reacted by punching him in the shoulder at the same time.
In the beginning, though, their friendship was unstable as Abby was still mourning Kate who had been murdered by Ari, Ziva's half-brother. Abby even resented Ziva getting praise and began saying her surname incorrectly just to irk Ziva, a trait that Paula Cassidy would use in the Season 4 episode, Grace Period (episode).
But the two soon became close friends. In one episode, Ziva presents Abby with a "Chocoholics Choice" cupcake as a thank you for allowing her to stay at her apartment while her home was being fumigated. The cupcake later went missing and it was soon revealed that McGee who hadn't eaten anything all day had in a moment of weakness promptly devoured the cupcake, using latex gloves in hopes of covering his tracks but Abby later found out and expressed her displeasure at what he had done. McGee also earned two head-slaps from Tony and Ziva for his actions.
In the Season 7 opening episode, Truth or Consequences (episode), Abby embraces Ziva in the squad-room after Gibbs, Tony and McGee came back from Africa, bringing a physically weak but alive Ziva with them.
Abby and McGee dated briefly during Season One. However they ended the relationship later in the season and have remained good friends ever since. Abby often jokes around with McGee, sometimes sexually. In one case, she said, "Remember, I am one of the only people in the world who can kill you and leave no... forensic... evidence."
In some instances, she becomes jealous when McGee projects his attention onto another woman. He also shows signs of jealousy when she is friendly towards other men.
In Pop Life (episode), Abby makes a comment about men "being fakes." When McGee is affronted, Abby responds to him with, "Your tat is real, and you don't disappoint me."
in the Season 1 finale episode, Reveille (episode), McGee is left stunned when realizes that he slept in a coffin and further more shocked when Abby remarks "Not just slept, hinting that they might have slept together.
In the Season 9 episode, Life Before His Eyes (episode), in one of Gibbs's alternative universes, it was shown that Abby and McGee were married to one another and that alternate universe version of Abby mentioned that she was happy with her marriage.
- "Hi, Leon. I'm just doing an experiment."
- —Abby talking to Vance in the NCIS: Los Angeles Season 1 episode, "Killshot".
Abby is one of the few people whom Director Vance permits to address him by his given name of Leon. This is Director Vance's way of demonstrating his respect for her abilities and her work ethic. The only other person allowed to address Director Vance by his given name is Gibbs.
Director Vance's respect for Abby's abilities was first demonstrated during the events chronicled in the episodes entitled Cloak (episode) and Dagger (episode) when only she was informed of the plan to trap the "mole" within NCIS prior to its being set.
This respect was recently reaffirmed when Director Vance called her in to facilitate and speed up the process of forensic analysis in a case being investigated by the team from the Office of Special Projects led by G. Callen, as chronicled in the NCIS: Los Angeles Season 1 episode, Killshot (NCIS:Los Angeles) (episode) which featured a crossover between the two shows although Abby and Vance were the only two characters from the main NCIS show to appear in the episode.
Behind the Scenes
Abby is played by American actress Pauley Perrette. Perrette shares many similarities with her character: she was born in New Orleans, and likewise has a Master's Degree in Criminology. Abby's claimed reason for her interest in forensics was borrowed from Perrette's life: both women lived near a wrecking yard, and becoming intrigued by examining the wrecks and guessing the causes of the damage done to them. Perrette studied for her character by touring the real NCIS offices and meeting with its forensic specialists.
It should be also noted that while Abby's hair is black, Perette is a natural blonde in real life.
One significant difference is that some of Abby's tattoos are Perette's own, but most of the others are fake, which require Perrette to spend at least forty-five minutes in makeup for a typical episode.
Among the confirmed fakes are the large cross that is sometimes seen on her back and the spider web on her neck which Perette has admitted to disliking in interviews and she also wishes for the writers to have a storyline where the tattoo is finally removed but it hasn't happened yet.
The cross is applied only in the episodes when Abby's bare back is exposed (such as Silver War (episode) and Witch Hunt (episode) while the spider web was added because Donald Bellisario wanted the character to have a tattoo that would be visible (almost) all the time.
However, now that Perette has gotten the tattoo of a flower on her back, the cross has stopped being used altogether as the flower has been regularly seen in various episodes of Season 8 and 9 of the show.
In addition to being an actress, Perrette is also a civil rights activist, and a published poet.
- Abby is the only NCIS character to have appeared on JAG, NCIS, NCIS: Los Angeles and NCIS: New Orleans.
- Drives a 1931 Ford Coupe Hot Rod which was seen in the Season 5 episode, Dog Tags (episode).
