Biography
Pre-Series
Born in an unknown State, Whistler was the daughter of an unnamed couple and also the sister of Noah Whistler.
After finishing high school, she began attending Northwestern University where she was also part of a sorority while Noah went on to join the United States Marine Corps, rising to the rank of Captain.
In 2009, tragedy struck when Noah died during an ambush in Taji, Iraq.
After presumably graduating from Northwestern, Kate practised for some time before she ultimately joined the DIA- Defense Intelligence Agency.
While with the DIA, she was stationed in DC and while at a conference in Hawai'i, met NCIS Special Agent Lucy Tara at a bar.
At some point, an unnamed FBI Special Agent in Charge took Kate under his wing, serving as her mentor.
In later years, Whistler became a liaison between the DIA and NCIS, often arriving at NCIS Hawaii Headquarters in Pearl Harbor to provide NCIS Special Agent Jane Tennant and her team with information concerning their latest case, essentially cutting across a lot of red tape or to warn them to back off if her DIA superiors believed the case the NCIS Hawaii team was investigating had access to highly-classified knowledge the team wasn't cleared for.
It's also presumed that her job at the DIA was that of an officer as she was not seen carrying a sidearm or working in the field.
