Tony's father's return will come with a bit of controversy. The NCIS agent will show interest in another woman other than Ziva David, however, she's already with his father.

"This woman could potentially be Tony's new stepmom, and a big part of the story is her age and the awkwardness that brings to Tony," the show's executive producer Gary Glasberg told TV Guide in a January report. "Prior to meeting her, Tony tries to find out as much as he can about who she is."

The young new woman may even cause a rift between father and son, according to the article.

Weatherly also posted two black-and-white photos of himself on Twitter to tease upcoming scenes.

"From the set of #ncis @michaweather does noir," he captioned one.

"Horror movie? #ncis on set madness," he captioned the other.
