Some NCIS fans are getting tired of Tiva. Others can't get enough. Regardless, the lingering issues and unanswered questions surrounding Tony and Ziva keep piling up.

Will this season offer any resolution?

As far as what happened between them in Paris earlier this year, Michael Weatherly (Tony) thinks he has the answer ... or lack thereof. Confused yet? Is that the point?

“The truth of what happened is probably something that can be discovered inside the episode itself,” Weatherly tells EW, semi-cryptically. “If you really listen to what they say, I think that it's pretty clear what happened: Nothing.”

Boo.

For her part, Cote de Pablo (Ziva) thinks some questions should stay unanswered:

“If you solve something completely, especially on a TV show like this, it is no longer that fun. It is a complex relationship, and there is so much more to explore.”

That's a fair point.

As for whether they'll ever become more than co-workers, Weatherly opines: “I'm very happy with where things are right now, but you never know what will develop. The writers may one day think they’ve cracked the chemistry riddle."

"They may come to think they can make us a full-on couple without killing the chemistry and tension that make people watch. But making the audience get their cake and eat it too is not outside of [exec producer] Shane Brennan’s wheelhouse.”
