Like the JAG Season 8 episodes, Ice Queen (episode) and Meltdown (episode) which introduced the original NCIS team, this episode and Legend Part 2 (episode) both served as the first part of the two part back door pilot for a proposed spin-off series and also introduced the cast who with the exception of Lara Macy (Louise Lombard) would later go on to appear as main characters in the first ever NCIS spin-off series, NCIS: Los Angeles.
