12/21 - Master Sgt. Crystal L. Anderson was an extra in a filming of LOST in Hawaii. She played a member of a church congregation. The scene was designed to depict the mental flashback of a character in the show named Mr. Eko, played by veteran actor Adewale Akinnuowy-Agbaje. Per an interview with a local army newspaper, she says Mr. Eko is "king of the warlords" in Nigeria. He enters the church with other warlords and asks his brother, a minister in the church, to ordain him as a minister. Everyone is frightened, knowing Mr. Eko's reputation, and the church is cleared, so only two warlords, Mr. Eko and his brother, are left. Source: The Transmission

01/04 - Mistaking Shannon for an Other, Ana Lucia killed her. So it's not a shock that the fuselage folks have been a little apprehensive about the tail-section survivors joining their camp. Those feelings intensify on January 11 when the imposing Mr. Eko learns Charlie's got a Virgin Mary statue, and demands the recovering junkie show him where he found it. That means a trek back to the downed Beechcraft full of heroin and a dead Nigerian "priest." "Eko [is] connected into the story of the drug plane," says executive producer Carlton Cuse. "People are curious about where that plane came from. We're gonna explain that." And what's Eko been up to with that big stick he's always carrying around? Reveals executive producer and cocreator Damon Lindelof, "He's carving Scripture on it." Remember the monster? We last saw it in May's season finale, when it appeared as a slithering mass of black smoke. "We will be seeing the monster in the January 11 episode," Lindelof says. Indeed, one character will have an up-close-and-personal encounter with the thing so viewers will get a better, longer look, too. Source: TV Guide (Printed edition)
