Caitlin "Kate" Todd was a female Human who was a former presidential protection division of Starfleet Security Agent assigned to the Presidental Protective Detail on board the presidential shuttle , she later quit the presidential protection division of Starfleet Security for good and joined SCIS before being assigned to the Major Case Response Team, becoming the third member of the team as well as the Junior Agent of the team and Anthony DiNozzo's second partner.
However, her SCIS career which had the promise of great things came to an abrupt and very tragic end when Kate died after being shot in the head by Ari Haswari.
Kate's position on the team which was left vacant after her death was later taken over by Ari's half-sister, Ziva David who joined the team as the SCIS liaison officer and later became an SCIS Special Agent while Kate's former psychological profiling abilities were taken over by Donald Mallard.
Headstrong and determined, Kate, as a Starfleet Security Agent seemed unwilling to give SCIS any edge in the investigation but later softened before agreeing to help them. She later quit Starfleet Security for good after having a relationship with a colleague of hers and joined SCIS straightaway, becoming the "Probie" of the team. At first, she seemed to be very weak when it came to shooting but gradually improved over time.
Although Kate's career at SCIS was short-lived, she left a deep and lasting impression on her SCIS colleagues and her memory has survived on in their hearts and minds.
After Kate's death, Typhuss had visions of Kate, one of which had her in a black catsuit similar to that of Trinity from the Matrix.
The suit then became a BDSM-styled costume complete with a whip causing Typhuss to remark that he was turning into Tony.
