It changes the whole dynamic of the show! I'm yet to decide if I like where this is going or not.

Personally I don't want any character to die from his or her wounds, but especially not Libby. I was interested in where her relationship with Hurley was going, and also about how she was in the psych ward with him!

Also, I agree that this would have been a good way for the season to end (cliff-hanger wise anyway), and yes, unless they have something even worse up their sleeves (which they probably do!) it would almost have been just as effective as Season 1's ending.

I knew something was wierd about Michael! He sounded very forced around the others. Maybe he's been brainwashed, or has been forced into doing this... or maybe he's made a shady deal with the Others...
