After leaving the show, Diane Neal went on to appear in a few episodes of "Suits" and "Power", but she would eventually return to her crime roots by starring in "NCIS" in 2010, playing CGIS Agent Abigail Borin (via IMDb). Neal left the show in 2014, and would later reprise her role as Abigail for three episodes in "NCIS: New Orleans" a year later.

Following her stint on "NCIS," Neal played Lisa Campbell for five episodes in the third and final season of "The Following." Her investigative roots continued in this Fox series led by Kevin Bacon, as Lisa also happened to be an FBI agent. Neal also appeared in an episode of "Blue Bloods" as Kelly Blake before disappearing from the industry for six years.

During her absence, she actually ran for congress in New York (via the Associated Press). This came after she graduated from Harvard University's extension school in 2018 with an associate degree, after beginning her studies there in 2009.
