Thanks to GreekCharmed for the link. I've posted this in rumours as it sounds more like the author speculating rather than any hard facts etc.
Thanks to the moves-like-a-bullet Heroes, Lost has sped up its storytelling pace considerably. It's about time. After an intriguing start, Lost, well, started getting lost ... again. But in the last few weeks we've learned how Locke (Terry O'Quinn) wound up in a wheelchair; that Juliet (Elizabeth Mitchell) still is in cahoots with The Others, Desmond (Henry Ian Cusick) has some pretty disturbing visions and women who get pregnant on the island die. The writers even offed such unpopular characters as Nikki (Kiele Sanchez) and Paulo (Rodrigo Santoro) in a wickedly fun way by burying them alive! Good stuff. The producer swear there's more. Like? They're not saying, but word is a few castaways won't survive. Yeah, I'm talking about you, Charlie (Dominic Monaghan) and Ben (Michael Emerson).
