NCIS is ticking all the boxes with its latest casting announcements. From brand new characters to returning faces to those gone way too soon, find out who will (or won't) join Gibbs' team in season 14.

Tony DiNozzo's (Michael Weatherly) farewell arc introduced viewers to FBI Special Agent Tess Monroe (Sarah Clarke) and MI6 Officer Clayton Reeves (Duane Henry). Although both actors initially had the option of becoming series regulars, only Henry is expected to return this fall. It would stand to reason that an Agency player would be easier to work into the DC storyline, but Reeve's continued presence could open the door for a new international adventure.

Closer to home, Gibbs' will recruit a whip-smart NCIS agent back into the field. Played by Jennifer Esposito, Special Agent Alexandra "Alex" Quinn will become a series regular when NCIS returns on Sept. 20.

"[Quinn] is an experienced agent who left field work and became an instructor at the Law Enforcement Training Center," Deadline announced. "Gibbs (Harmon) will lure her back into the field as part of his team, where he will take advantage of her sharp wit, quick mind and immense talent as a federal agent."

Quinn will make her debut in the season premiere. From the sound of it, the seasoned investigator will work to fill DiNozzo's comedic shoes. Tony possessed the sarcastic wit that kept the long-running series from falling into the doldrums, and it seems writers are ready to place Tony's dialogue in new hands.

Esposito previously starred on Blue Bloods, and the actress is excited to return home to CBS.
