Larisa Oleynik.  It took me a few seconds to recognize that name.  It’s Alex Mack from the classic Nickelodeon series The Secret World of Alex Mack (1994-1998)!  I grew up watching (idolizing and adoring) Oleynik because she wielded the most awesome superpowers including the ability to instantly morph into a puddle of silver liquid.  Well, now she’s all grown up and ready to star in the CBS reboot hit Hawaii Five-0.  According to TVLine, she will play “Jessica Kaye, an ex-CIA analyst and Harvard graduate with a degree in Political Science and a Masters in Global Security and Intelligence Studies who is fresh off the plane from Langley, Virginia.”  She’s joining the Five-0 team led by McGarrett and Danno because she is in hot pursuit of Wo Fat, McGarrett’s nemesis who had a hand in the murder of his mother (but he doesn’t know this yet).  Jessica “has a personal stake in the manhunt since Wo Fat was responsible for the murder of her fiancé, a well respected CIA field agent.”  Apparently Oleynik’s role will remain recurring for the rest of season one, and there’s an option open for her to potentially become a series regular next season.  Welcome back to the ‘waves, Alex Mack.
