Will Tony Return to 'NCIS' as Part of Ziva's Season 17 Arc?

Showrunners Steven D. Binder and Frank Cardea address the possibility of Michael Weatherly's character coming back.

It turns out that Ziva was the target of the explosion that took out her family's farmhouse, the one that presumably killed her. To get to the bottom of it and protect her family, Ziva used the opportunity to fake her death and go deep underground to uncover the truth. But there's still quite a bit about the past few years and what she's been up to that she hasn't spoken about.

Now it's looking like "Into the Light" will see the others questioning which side she's on. (However, we should also keep in mind that promos can be misleading.) Click through the gallery for the reasons we should and shouldn't trust Ziva.
