Forget Ziva and Tony for a moment, NCIS fans.

Producer Shane Brennan told TV Guide this week he's excited about a storyline he has planned for Abby this season, one that heavily involves Gibbs.

"[Abby] does have a special relationship with Gibbs, [who has changed] because of the journey he has taken over the past two-and-a-half seasons," Brennan said. "Most people will see that Gibbs smiles more now; he's kind of warming up. There's certainly more to learn about the relationship between Gibbs and Abby, and we play toward that in this special arc of Abby's."

In its seventh season, NCIS has firmly established itself as the top-rated show on TV.
