Michael Weatherly hasn't been seen in the world of NCIS since his exit way back in 2016. However, with fellow CBS drama Bull now over, Weatherly's work diary has suddenly freed up somewhat, leading NCIS fans to tip a surprise return in the show's milestone 20th season. Now, Weatherly has sparked further speculation with a Twitter update regarding both Tony and Ziva David (played by Cote de Pablo).

To recap, both Tony and Ziva are alive and well in the NCIS universe alongside their daughter Tali.

The trio, as far as fans are aware, are currently residing in Paris, France after leaving their crimefighting careers behind them.

But could they be about to return to Washington to reunite with the likes of their pals Timothy McGee (Sean Murray) and Jimmy Palmer (Brian Dietzen)?

One fan was keen for it to happen as they tweeted Weatherly earlier this month saying: "We all would rather look at you and Ziva reuniting and enjoying that moment."

Elsewhere, Kathy Svetz echoed this: "Please, please, PLEASE come back!!!!

"The show isn't the same without Tony, Ziva, & Gibbs. I (love) McGee & Jimmy but the rest have got to go!"

Meanwhile, Diane concurred: "Pretty please with sugar on top!!!! I miss Tony and Ziva, even more so since Gibbs/Mark Harmon left. 

"The current mix of characters aren't keeping my interest as much," they concluded.
