When we see Nikki shooting the scenes for Exposé, we hear how the bad guy on the show, The Cobra, is revelead. All along this really bad guy, the villain, has been in the middle of all the good guys. Another line they use in connection with this character is "Shrouded in mystery for the last four seasons". Could this be a clue that someone bad is planted among "our" good guys - the mysterious HIM for example?

Interesting thought.
It made me think of Ethan actually when I read your post - who we clearly saw was hanging with those two.

good catch, Rain. It is always a possibility!!!

I think it would be interesting if HIM turned out to be one of the Losties. Someone we never even suspected.
