According to showrunner Peter Lenkov, season 6 will kick off with a "huge action-adventure tale" where an investigation leads the Five-0 to an ancient legend. "It's a modern-day pirate treasure hunt with flashbacks to help tell the origin of it all."

Lenkov confirmed that Kono and Adam "did take the plunge" in an interview with TVGuide. "The premiere picks up maybe an hour or two after last year's finale. We'll see [Adam and Kono] be introduced as husband and wife."

Fans will also get to see the entire Ohana team let loose "...on the dance floor to tunes of We Are Family. At least, that's the plan," the showrunner said.

Speaking of Gabriel, Lenkov teased "the villain's real agenda is not personal".

He told TVLine, "Wo Fat was a villain that we had for years, but his agenda was very personal. For Gabriel, he's more of a sociopath. He's a bad guy because he's a bad guy. I don't think you're going to find out, at least for a while, what his real agenda is, but it's definitely not personal."
