The Fate of Alden Parker: Gary Cole’s Role in Season 23
After taking over team leadership duties from Gibbs, Alden Parker has grown into the role — but he still feels like a bit of an outsider. That’s expected to change in Season 23.
Writers are hinting at a deeper dive into Parker’s past, possibly even a personal vendetta that could drive the season’s overarching plot.
Any Sign of Gibbs? Let’s Talk About Mark Harmon
The big question on everyone’s mind: Will Mark Harmon return as Leroy Jethro Gibbs?
So far, no confirmation — but rumors suggest that Harmon may make a cameo appearance in a flashback or special tribute episode. Harmon still serves as an executive producer, so the door is always open.
What About Ducky? Honoring David McCallum
Season 22 saw NCIS say goodbye to one of its most beloved characters, Dr. Donald “Ducky” Mallard, following David McCallum’s passing. Expect Season 23 to further honor his legacy, possibly with a dedicated tribute episode or emotional callback moments involving Palmer.
Tim McGee’s Story Arc: Where’s He Headed Now?
McGee’s been through a lot. From tech nerd to senior field agent, his evolution has been fun to watch. Season 23 may finally see him grapple with taking over the team, or perhaps even leaving NCIS to explore life beyond the agency.
Could this be the season he walks away?
Big Twists Teased by the Showrunners
Showrunner David North teased in a recent interview that Season 23 will “shake things up more than ever before.”
That could mean:
-
A shocking death
-
An undercover betrayal
-
Or even a returning villain from a past season
Keep your fan theories ready — this season won’t play it safe.
How ‘NCIS: Origins’ Ties Into Season 23
The NCIS: Origins prequel series about young Gibbs might not seem connected, but fans should pay attention. Insiders have confirmed that details from ‘Origins’ will impact present-day storylines in Season 23.
So yes — watching both shows will be totally worth it.
Behind-the-Scenes Changes: New Writers and Producers?
Season 23 will bring fresh creative voices into the writing room. A new team of producers and scriptwriters has been added to keep the franchise feeling modern without losing that signature NCIS charm.
Think faster pacing, tighter plots, and more serialized storytelling.
