Off the Grid is the 12th episode of NCIS Season 14 and also the 319th episode of the entire NCIS series.
After spotting the brother of an NCIS Most Wanted suspect, Gibbs immediately assumes a former alias and goes undercover with their infamous anti-government militia group while Bishop and Reeves work together on an off-the-books investigation.
- The circumstances behind Gibbs undergoing a deep cover operation previously alluded to in Blast from the Past (episode) are elaborated in this episode.
- Bishop reveals that Qasim Nassir died sometime between this episode and the previous one from the shooting.
- Reeves and Bishop are revealed to be illicitly doing investigations on Kai Chen.
- This is the 319th episode overall, airing before the 316th.
- Gibbs's alias, Leland Robert Spears, is the same alias that was stolen in the Season Twelve episode, Blast from the Past (episode). This was also given a reference in the beginning when the terrorist mentioned that he thought Spears was dead.
- It is unclear whether the undercover case Gibbs was working on to catch the Whitmans' in 2001 is before or after the undercover case he was on in Baltimore in 2001, that involved him meeting DiNozzo.
