List of Appearances

Abigail "Abby" "Beethoven" Sciuto is the Chief Forensic Scientist for the NCIS Major Case Response Team.




Abby as a young girl. From the Season 10 episode, "Hit and Run".

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.

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 8Edit

Like her colleagues, NCIS Special Agents Leroy Jethro Gibbs, Anthony DiNozzo, Vivian Blackadder and Donald Mallard, Abby made her debut appearance in the JAG Season 8/NCIS backdoor pilot episode, Ice Queen (episode).

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 1Edit

[File:Vlcsnap-2014-10-22-22h31m47s244.png|thumb|left|Abby in the Season 1 premiere episode, "Yankee White".]] 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.

NCIS Season 2Edit

NCIS Season 3Edit

In Kill Ari Part 1 (episode), the Season 3 premiere episode, like the rest of the NCIS team, Abby was left grief-stricken and devastated at Kate's murder at Ari's hand.

She was seen in her lab, glancing at a drawing 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 4Edit

NCIS Season 5Edit

NCIS Season 6Edit

NCIS Season 7Edit

NCIS: Los Angeles Season 1Edit

Abby made her first ever official appearance in the NCIS: Los Angeles Season 1 episode, Killshot (episode) where she helped provide Vance assistance on a case concerning North Korean assassin Lee Wuan Kai.

"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".

In Random on Purpose (episode), Abby arrived in Los Angeles in person to aid the Office of Special Projects team in capturing a serial killer 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 Second 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.

Thankfully, the Office of Special Projects Team led by G. Callen saved Abby and killed the murderer although Abby was presumably left traumatized after her near-death experience.

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 again and 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 8Edit

NCIS Season 9Edit

In Nature of the Beast (episode), Abby, like the rest of the NCIS team expressed concern about DiNozzo's unusual behavior.

NCIS Season 10Edit

Geronimo and which had killed Navy Lieutenant Lewis Collier and Lieutenant Duncan.

NCIS Season 12Edit

NCIS Season 13Edit

In Sister City: Part 1 (episode), Abby is panicked by the thought that her adoptive brother Luca Scuito could have been killed in a plane accident, and later that he is missing and could be in danger. Once he was found, she often found herself getting frustrated with Luca's naivety about the situation and his need to protect Eva.

Abby, like her NCIS colleagues, is left devastated when it is revealed that former agent Ziva David did not survive a mortar attack on her farmhouse in Israel. She is also sad to see Tony leave the team.



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 with the hair itself often hanging past Abby's shoulders and she also ties it up in buns if she's attending church.

She also has at least twelve tattoos across her body.

She is also extremely talented at hacking with her skills presumably even matching those of her former boyfriend, NCIS Special Agent Tim McGee and also NCIS Tech Operator Eric Beale and NCIS Intelligence analyst Nell Jones.
