Relationships
Abby gets along well with all the rest of the team. She is very fond of Ducky, who uses her full name, Abigail. (She is called Abby or Abbs by most everyone else, except Director Leon 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's relationship with Tony is a friendly 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. In "Twilight," after Tony narrowly avoids being part of an explosion on his first day back from sick leave after getting pneumonic plague, she runs at him and hugs him so hard he nearly falls over. In the episode, "Frame-Up," she almost single-handedly unravels the forensic evidence used to frame Tony of murder in order to clear his name, then subdues the killer – her assistant – when he threatens her with a knife. 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 starts with a rant criticizing Ziva for her continuing mistrust of Tony, which, in trademark Abby fashion, ends with her saying how worried she was about Ziva, and hugging her. This then sparks a confrontation between Tony and Ziva that sees their relationship restored to normal.
Before her death in the line of duty, Special Agent Caitlin Todd was a close friend of Abby's. 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 first arrived at NCIS, as she was the half-sister of Ari, who killed Todd. Abby would scribble over pictures of Ziva and frequently mispronounce her surname to annoy her. Later, upset by Ziva's calm response to Gibbs being injured in a bombing, Abby slapped her. 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 did not know why Abby did so, but eventually, she overcame this, and Ziva now accepts Abby's hugs with no problems.
She is friendly with Medical Assistant Jimmy Palmer. She has helped him with an autopsy and "Rolfed" him when he injured himself in the morgue in "Life Before His Eyes". In "Newborn King", Palmer brings his future father in-law, Ed Slater, to NCIS. Later in the episode McGee visits Abby to see she has locked the two in the back room. Jimmy states if Slater hadn't made a comment about Abby's tattoo then they wouldn't be in time out, implying he took Abby's side. Jimmy also chose Abby to be his Best Woman at his wedding in "The Missionary Position".
