Not only will the Five-0 leader meet a new female friend, but the series will also treat viewers to a flashback to a six-year-old Steve.

Penned by Eric Guggenheim ("Makani 'Olu a Holo Malie," "Hau'oli La Ho'omoaika'I") and directed by Bryan Spicer ("Ho'oilina," "A'ohe Kahi e Pe'e Ai"), the episode will introduce a woman from one of John McGarrett's old cases.

"After [John] died, this woman, on the anniversary of his death, always shows up at his grave to basically thank him for everything he had done," said executive producer Peter Lenkov of the upcoming character, according to TV Guide.

Their fateful meeting won't harbinger a romantic relationship, however.

"Everybody's selling it as a love interest, but really it's a friendship," Lenkov told TV Line. "McGarrett meets a woman on the anniversary of his father's death, and they share the common trauma of both losing a parent very early on. And that's going to play into an arc."

Will McGarrett's [Alex O'Loughlin] flashback have to do with this new woman's former case, or will it involve another cold case the younger McGarrett will reopen? Find out more when Hawaii Five-0 airs Fridays at 9 p.m. ET.
