Bryn Fillmore was a Special Agent with NCIS.
Much of Fillmore's past is unknown but at some point, after graduating from FLETC, she was eventually assigned to the Navy Yard in Washington D.C.
NCIS Season 7Edit
As a temporary replacement, Fillmore's time on the main NCIS Major Case Response Team led by NCIS Special Agent Leroy Jethro Gibbs was unknown but what was known is that she served as an interim replacement for Rebecca Hastings.
Unable to handle her colleagues, NCIS Special Agents Anthony DiNozzo and Timothy McGee whom she later described as being "annoying", "childish" and even regarding McGee as being DiNozzo's sidekick, Fillmore eventually quit the team for good with her resignation letter having taken a month to write.
It is not known what became of Agent Fillmore after she resigned from the team.
