NCIS returns with its third to last episode of the twelfth season tomorrow, April 28!

Which Terrorist From An Earlier Episode Of Season 12 Might Be Back For The 'NCIS' Finale?

In the episode called Troll, the team will be joined by fellow Special Agent Ned Dorneget (Matt Jones), who is being sent over from the NCIS Cyber Operations Division to assist on the murder case as noted in the press release.

On Thursday, the NCIS YouTube channel uploaded a preview of the episode, which can be viewed below.

When Will The 'NCIS' Season 12 Finale Air?

In the preview, a car smashes through what appears to be a diner or restaurant and Dorneget is brought on to help the team.

"Reporting for duty, Agent Gibbs [Mark Harmon]," Dorneget says in the clip.

Dorneget is brought on since there is some connection to the Cyber Operations Division especially since the Navy warfare engineer who is found dead worked out of the Office of Naval Intelligence.

Also in the clip, it is revealed that the case is "top secret" with Timothy McGee (Sean Murray) briefing Gibbs, Eleanor "Ellie" Bishop (Emily Wickersham) and Tony DiNozzo (Michael Weatherly) by sharing, "Details are classified."

That prompts Gibbs to ask, "Classified? McGee, by who?"

The ending is teased as being "killer" and a clip of Abby Sciuto (Pauley Perrette) asking, "Where's Gibbs?" while in her lab with Dorneget is shown before cutting to a clip of Gibbs pointing his loaded gun at someone while on a bus.

NCIS airs on Tuesdays at 8 p.m. ET on CBS.
