Per TVLine's Matt Webb Mitovich, there will be another addition to the core cast when the second season of CBS crime drama "Hawaii Five-O" returns.
Lauren German ("Happy Town") will join the show in the series regular role of a beautiful and smart former Homeland Security officer who has been picked by the new Governor (Richard T. Jones) to join the Five-O task force. Her job is not only to fight crime, but also keep the team in check - and she's a potential love interest for Steve McGarrett (Alex O'Loughlin).
Still no word about whether Larisa Oleynik might be back for more. But regarding the above news, a series regular addition of her character of CIA analyst Jenna Kaye is now more and more unlikely.
