LOST

I so have to rant and rave about a little thing most LOST addicts have forgotten. What ever happend to the french woman?! She is the key-mark my words. Remember when the survivors were talking about the ‘monster’? And she said it was just security? ok:
A. this security thing kills people.
B. now, they are threatend it’s after all the survivors
C. obviously the french woman knows more than what she’s telling.

conclusion: to save their lives they should track her down again and make her tell them about the security smoke monster. WHY IS NOBODY SAYING THIS? She is the key- I know it.
