This episode is all about the final 5 minutes and what a stunner it is. It took me totally by surprise the first time I saw it as I'm sure it did with everyone else. In a nut shell, Michael shoots and kills Ana Lucia and Libby, opens the armory where "Henry Gale" is being held a prisoner. We are expecting Michael to shoot him. But he doesn't. He turns the gun on himself and then BAM! Fade to black. What a cliffhanger. It still works, no matter how many times I see the episode.

The flashbacks are about Ana and how she ended up in Australia to begin with. This is also another pivotal moment because the person that hires her as a bodyguard was none other than Jack's father, who was there to see his (not shown on screen) daughter. This too will have major implications later on. If you've never seen Lost, this is a monumental episode.
 
Poor Hurley. His first date with Libby is not how it's suppose to end.

There is a good rumor that has been floating around about this episode since the day it aired. Many have speculated that both the Ana Lucia and Libby characters were killed off because of Michelle Rodriguez and Cynthia Watros were involved in a drunk driving incident which prompted their ouster. The producers of the show have always said their death's were planned long before. So, who knows what the real story is........
