Hawaii Five-O won't air a new episode until March 21. That's the bad news.

But here's the good news: viewers will meet Larisa Oleynik's Jessica Kaye that night, a new team member who will shed light on Wo Fat and his connections to McGarrett's father.

"She brings some of that Wo Fat backstory to light and sheds new light on his character. She sort of reinvigorates McGarrett's interest," producer Paul Zbyszewski tells TV Guide.

Will Wo Fat's plot be wrapped up this year? Not likely, adds Zbyszewski: "We see him more in terms of a series-long character, much like the original Five-0."
