Francine Orr / Los Angeles Times
By Patrick Kevin Day and Ryan McGee After 4 1/2 seasons, we've gotten pretty familiar with our most favorite group of island castaways since Gilligan and company. So familiar, in fact, that the producers have jettisoned the once de rigeur flashbacks into our main characters' pasts. We know all about Kate's daddy issues, Jack's daddy issues, Locke's daddy issues, heck we even know about Ben Linus' daddy issues. But even though we've had many questions answered, there are still a lot of slippery characters haunting the periphery of our favorite show on TV. Some of them seem helpful but probably aren't (Matthew Abaddon, played by Lance Reddick at left), and others exude an air of menace even while working on the side of the angels (Ms. Hawking). Here are our thoughts and speculations on the most mysterious characters in a series filled with mysteries.
