That's Abby Sciuto(:

Abby has a gothic style of dress, including black dresses and t-shirts, mini-skirts, and goth jewelry, including anklets and toe rings. She wears pigtailed dyed hair, and has at least eleven tattoos on her neck, arms, back, ankle and other places. While some of the tattoos are Perrette's and real, others are makeup, such as the large cross on her back applied on occasions when Perrette shows her bare back on camera. The spider web on her neck is not real either, as producer Donald Bellisario wanted the character to have a tattoo that would be visible (almost) all the time. Abby also has a stuffed hippo named "Bert" that makes flatulence noises when squeezed, which has been used for comic effect when Abby is upset. Her biggest pet peeve, as revealed in Season 5's Lost and Found by Tim McGee, is people who claim to be vegetarians but still eat chicken; her second biggest pet peeve is people who mis-handle evidence. Like Gibbs, Abby enjoys caffeine, primarily in the form of a fictional drink called "Caf-Pow". (According to Perrette, the actual drink was Hawaiian Punch for many years, but was switched for unsweetened cranberry juice when the actress stopped eating and drinking refined sugar.) When changing the artwork in her lab, she states that she has a "Chagall feeling", a reference to Marc Chagall, a Jewish Belarusian artist whose main works came from fantasy and dreams. Her favorite term for something out of the ordinary is "hinky". It is also shown that she enjoys attending concerts, but her failure to wear earplugs at one of them left her with temporary hearing loss the next day, forcing her to ask DiNozzo for help analyzing some audio evidence. Abby has shown a tendency to become very agitated, to the point of near-panic, if any of the team are seriously hurt. When Gibbs was admitted to hospital, Abby ended up on the verge of a nervous breakdown, pacing back and forth while delivering a rambling, disjointed stream-of-consciousness plea that explained (among other things) how close she and Gibbs are, the reason she was arriving after visiting hours, how she felt about Gibbs being injured, and how important it was to her that Gibbs not die from his injuries. Sciuto is well-versed in her field of study; she is rarely stumped by the puzzles that Gibbs' team present to her. Abby has been shown to have skills in traditional forensics, computer forensics, and hacking. She has implied that she has a PhD in chemistry. It has been shown that she does all the work on the evidence herself. In season 3, when she is given an assistant, Charles "Chip" Sterling, she revolts but puts up with him. After she discovers that he has framed DiNozzo for murder, he threatens her with a knife; she promptly subdues him, hog-ties him with duct tape, and insists on being allowed to work alone from then on. It has been shown that she has a younger brother. She also mentioned that her grandmother was an Olympic swimmer who won a silver medal and that she had an uncle named Teddy who owned a bar. She also has an Uncle named Horace whom she referred to as Horace "the Haggler" during an episode. In "Kill Ari Part 2" at Caitlin's funeral, it is revealed that Abby grew up in New Orleans (as did Pauley Perrette). In the episode "Seadog", Gibbs tells Tony that Abby knows how to use sign language because both of her parents were deaf. It was stated in the NCIS: Los Angeles episode "Random On Purpose", that Abby is in her late 20s. Abby is a hearing child born to deaf parents and likes her music loud. Abby has stated that she dreams of visiting the Galápagos Islands, Tel Aviv, and Dollywood before she dies.[10] Abby graduated with full honors from LSU with a triple major in sociology, criminology and psychology. She earned her master's degree from Georgia State University in criminology and forensic science. Sciuto's interest in forensics came from living near a wrecking yard and being intrigued by the cause and effect of the wrecks. Abby gets along well with all the rest of the team, particularly McGee and DiNozzo. She is very fond of Ducky, who uses her full name, Abigail. (She is called Abby or Abbs by most everyone else, except Director Vance, who calls her Ms. Sciuto.) Abby is fiercely loyal to the team, and considers them family which is shown by her distress when one or more of them is in serious danger. Abby and Gibbs have a very strong bond, and like Ducky, she has no fear of him, calling him by his last name. Gibbs is often seen giving Abby kisses on the cheek, and hugging her, especially when she does good work on the cases she works on. Sometimes, he even massages her shoulders. He often brings her a fictional drink called Caf-Pow, her favorite drink, when he arrives at the lab for information on their current case, or when he comes in response to her call on something she discovered with said case. Gibbs often tolerates Abby's goth dress style as he knows she does a great job in her work. Abby sometimes turns to Gibbs when she needs to talk about something personal that is bothering her and he helps by listening to her. Both Gibbs and Abby are proficient with American Sign Language, as Abby grew up with deaf parents. On several occasions, Gibbs has admitted that Abby is his favorite, a fact that doesn't escape the rest of the team, but they don't begrudge her for it. Gibbs has also shown that he can be as protective of her as any good father could be. For example, in the episode "Bloodbath", she was threatened by a hit man hired by a defendant in a case in which she was testifying, which was also complicated by an ex-boyfriend, named Mikel Mawher (guest star, Vincent Young), against whom she had a restraining order, but who then called her in violation of the order. When Gibbs found out about this, he pointedly told Mikel, "The only reason you're still able to walk is because I never heard about you until today!" Sometimes, that protectiveness extends from the rest of the team as well. For example in the episode Spider and the Fly, Alejandro Rivera came to NCIS and began to threaten Abby for not sending in that report about the murder of Pedro Hernandez, Rivera's father whom Gibbs had killed twenty years previously in revenge for Hernandez killing Gibbs' first wife and young daughter. The entire team, including Ducky and Director Vance, ordered him to leave her alone and to not harass her, or to be escorted forcibly from NCIS Headquarters. He left of his own accord, but was later arrested for attempting to kill Gibbs and his father at a safehouse, and accidentally killing his sister, Paloma. Gibbs' concern for Abby's safety is such that he will even drop his trademark cup of coffee if she is in serious danger. Twice this occurred, in the episode "Kill Ari" when Ari shot at her while she was in her lab, the other time was in the episode "Driven" when she was trapped inside an experimental humvee which had filled with exhaust, which could have suffocated her. Abby's relationship with Tony is a brother-sister one, with the two making friendly, non-hostile jibes at each other, and squabbling about various topics, such as movies and personal possessions. Abby is perhaps the only member of the NCIS cast who displays a love and knowledge of movies that even comes close to matching Tony's. Her sisterly affection for him is displayed through the many hugs she gives him after he arrives back in the office following time away, or after his life had been at risk. In the episode, 'Frame-Up', she almost single-handedly unravels the forensic evidence used to frame Tony of murder, in order to prove his innocence, (not to mention the excellent way she dealt with her erstwhile assistant, who had framed him. When he tried to pull a knife on her, she tied him up with duct tape, immobilizing him.) while the explosion of Tony's car in 'Bury Your Dead' causes her to become increasingly obsessed with her work, in order to prevent thoughts of his possible death. In 'Reunion', after Tony, McGee and Gibbs rescue Ziva from Somalia, Abby is the first to launch into Ziva about her mistrust of Tony, in Tony's defense, which sparks a confrontation between Tony and Ziva that sees their relationship restored to normal. Abby and former team member Caitlin Todd (deceased) were close friends; they often hung out after work, and Abby is one of the few to know what Kate's tattoo actually is. Abby was at first cold to Ziva David when the latter arrived at NCIS, because of her link with Ari, who killed Todd. Abby eventually came around, and she and Ziva became good friends. This was solidified in the episode "Capitol Offense" when Ziva, in gratitude for Abby allowing her to stay at her place (Ziva's home was being fumigated for termites), bought her a "chocoholic's choice" cupcake. The cupcake soon vanished, and Abby brought out all her forensic know-how to find it. Ultimately, it was McGee who had taken the cupcake, angering Abby and the others. At first, Ziva flinched whenever Abby would hug her given that she didn't know why Abby did so, but eventually, she overcame this, and Ziva now accepts Abby's hugs with no problems. She had a relationship with McGee which she stated that she would like to keep casual. Although the relationship ended late in season one, they both have exhibited jealousy when someone of the opposite sex pays attention to the other. There continues to be some erotic teasing and tension between the two, implied through such facts as McGee's apparent ability to describe the inside of Abby's bedroom in his novel. After finding out Abby sleeps in a coffin, he said, "You told me it was a box sofa," indicating he has at least stayed over. The implications went farther when he added, "I can't believe I slept in a coffin," and she wryly replied, "Not just slept."
