You're right Roco there
is something about her...there's more shocking Libby stuff to come in later eps, that's all I'm saying

(I've seen clips on the net). What I will say is, even having seen what I've seen I've still got a lot of unanswered questions about her. In fact, I was reading on Lost pedia (full of spoilers btw!) that there's a lot of buzz among Lost fans wanting to know more about her & just how integral she is to the whole ethos of the show!
