A throwback NCIS reunion is coming to Bull this season.

Nowadays, NCIS legend Michael Weatherly stars on Bull, which is coming to an end after six seasons. But for one of its last episodes, Bull is enlisting the help of another former NCIS star: Sasha Alexander.

NCIS reunion on Bull

This reunion goes way back. On NCIS, Sasha Alexander starred as "Caitlin Todd," but only in the first two seasons. Michael Weatherly finished playing "Tony DiNozzo" in season 13.

But the two are together again for the end of Bull. It turns out Alexander is directing an upcoming episode. She shared a photo of the nice reunion with Weatherly on set.

"Reunited and it feels sooo good," Alexander captioned her photo. Weatherly also reacted on Twitter, posting a video teasing fans about the reunion.

"I should post something with us talking, right?" Weatherly said in the clip, before tilting his head and making a sly face. Fans are still waiting for a follow-up from Weatherly.

Also interesting:

It looks like Alexander will direct the 20th episode of Bull this season, which is still weeks away. Bull is off until March 31 and that will be episode 15.

Sasha Alexander, now 48, was last seen on NCIS in season 12. Fans will remember "Caitlin Todd" was killed off in an early season shocker, but she still appeared in a few episodes later on. She and "DiNozzo" even had some memorable chemistry.

NCIS fans should enjoy all the memories from the unexpected reunion at Bull.
