With only a few episodes of Season 2 left to film, Vanessa warned viewers to expect changes and "big surprises."

"We're shooting Episode 18 right now," she told Distractify of the latter half of the series’ second installment.

Although viewers have only gotten glimpses of Jane’s backstory thus far, Vanessa teased we’ll learn the truth about the single mother of two’s childhood sooner than we think. Jane’s journey is largely inspired by Vanessa’s true life story, which for the actress, can get “pretty emotional.”

“It just comes from a real place," Vanessa explained.

“[The writers] actually pulled from my real life and growing up without my mother and leaning on my father and my father being in the military. And just how I kind of had to put on my armor at a young age, so to speak, and get myself ready for the world. They dive into that in [Episode 18].”

The episode introduces a new cast member, who stars as a young Jane Tennant. “I haven't met her yet, I've just seen her tape,” she shared. “It's gonna be emotional, but it's also exciting.”

“It shows what makes me tick and gives the viewers a reason why I might be a little harder on not only myself, but you know, my family, [and] my team,” the actress added. “It's peeling back the layers of the onion. And so I hope people welcome it because it is a little scary, knowing it's your real life.”

We can only imagine what’s to come as Season 2 of NCIS: Hawai’i has already seen some pretty exciting moments thus far — one of which includes the NCIS: Hawai’i and NCIS: Los Angeles crossover event.

Since then, showrunners announced that the latter is coming to an end after 14 seasons.
