Rogue is the 1st episode of NCIS Season 14 and the 307th episode of the entire NCIS series.
When a car explosion leaves a Navy Commander dead, his Marine wife unconscious and their teenage daughter unharmed, the NCIS team investigate and discover that there's a connection to an NCIS Special Agent who went missing six months ago while on a deep undercover assignment in Argentina and as the case goes on, NCIS Special Agent Alexandra Quinn, an instructor at FLETC arrives at NCIS HQ and begins shadowing the team in order to find out why Gibbs rejected the eight agents she recommended.
- It's revealed that since DiNozzo's resignation and McGee's subsequent promotion to Senior Field Agent three months ago, there have been at least eight possible replacements for McGee's former position, all trained by Alexandra Quinn but none have lasted due to Gibbs firing them.
- Fornell is revealed to be living at Gibbs's house as he recovers from the injuries he sustained in Homefront (episode).
- Bud Roberts Jr. returns and it's revealed that he has been promoted to Captain.
- McGee is revealed to know Bud and Bud's JAG colleagues, Captain Harmon Rabb and Marine Colonel Sarah MacKenzie.
- NCIS Special Agents Nicholas Torres and Alexandra Quinn are both introduced for the first time.
