After the Videocall between the NCIS team and Sebastian and Loretta has ended, the screen shows the encryption matrix used, called NX01. NX01 was the registration number for the Spacedhip in Star Trek: Enterprise, captained by Jonathan Archer, played by Scott Bakula.
Isabella Hofmann played Nancy Nolan. She played a judge on NCIS (2003), which was spun off from JAG (1995). On JAG, Hoffman played the recurring character Meredith Cavanaugh in 18 episodes, so she has been three different characters on shows that exist in the same TV universe.
