Pretty strange Lost Moment this week...
Upon first viewing, you think "Whoa - what are Charlie and Hurley up to? Something dangerous where they could be killed? What does Hurley mean by "If you don't die, then we win"? Have they found some way go get off the Island?!"
And then logic sets in. Listen to the tone of Hurley's talking. It's weird, as if he's doing an impersonation of someone who is giving a serious speech, when in reality they're probably talking about something trivial.
So what could it be? Well, based on the other Lost Moments, and the centricity of the episodes coming up, I'd be willing to bet this has something to do with Desmond and his powers. Perhaps they are planning a trip to the Imploded Swan Hatch to see what remains? Perhaps the "winning" they are talking about is "beating" Desmond by actually finding out what happened to him, since he won't tell them himself.
That's my best guess anyways. Comment away!
