Spoiler Alert: 'NCIS' Spoilers
Spoiler Alert: 'NCIS' Spoilers
With NCIS already a few episodes into its ninth season and all of last season's cliffhanger questions answered, it's back to business as usual for Gibbs (Mark Harmon) and the team.

But don't worry, that doesn't mean CBS will let the show get stale. There are a handful of great guest stars coming on board this season and some familiar faces returning.

NCIS spoilers ahead. Don't say I didn't warn you.

Cruel to be kind?

Scott Wolf (V, The Nine) made his first appearance on NCIS during the ninth season premiere as FBI Agent Stratton, or so he called himself. He clearly isn't exactly what he seems. "There are a lot of layers to the character of FBI Agent Stratton and I think we're all looking forward to seeing how things evolve," Executive Producer Gary Glasberg says. All reports refer to Wolf's role as "potentially recurring," but from what Glasberg says, there's little doubt Wolf will return at least once more this season.

Family Matters

Lily Tomlin (Laugh-In, I Heart Huckabees) has already appeared as McGee's (Sean Murray) grandma, Penny Langston, on NCIS this season, but there are even more family reunions coming up. According to Executive Producer Gary Glasberg, both Robert Wagner and Ralph Waite will reprise their fatherly roles to DiNozzo (Michael Weatherly) and Gibbs, respectively. We can also look forward to a new character, Abby's (Pauley Perrette) brother! There doesn't seem to be any news on who will play him but Glasberg says, "The story is so lovely and unexpected."

There are more NCIS spoilers regarding family. Melinda McGraw (Mad Men) has been cast as Diane, one of Gibbs' three ex-wives. Diane has been mentioned in several past episodes during exchanges between Gibbs and FBI Agent Tobias Fornell (Joe Spano), who also returns, both having been married to her. I'm guessing this episode will give us a little insight about Gibbs and will probably be filled with humor.

Which NCIS Character Are You?

Love On the Horizon

Ducky (David McCallum) will be getting a new love interest this season in the form of Cheryl Ladd (Charlie's Angels), who is set to guest star in late October. But Ducky may not be the only one getting lucky. Jamie Lee Curtis will be appearing in a two-episode story arc this season as Charlotte Ryan, a single mom who works for the Defense Department. Executive Producer Glasberg says, "Don't be surprised if there are sparks between Gibbs and Ryan. We're expecting some real chemistry."

It's looking like the ninth season of NCIS will be full of fun stories and great characters. How are you liking the season so far? Is there anything you're particularly looking forward to? Leave your comments below!
