Do NOT read if you don't want to know, but I just found out HOW the female on Lost dies and ... I want to cry. I'm not kidding.

It's so shocking. So good. And so unbelievable.

The doomed female dies NOT at the hands of the monster. But it is at the hands of someone we know who .... well, given this twist, just might BE a monster.

Holy @#$@@#! End of quote.

My first thought is that Vincent kills Shannon. Why did Walt leave Vincent with her? Or, if not Shannon, would Vincent kill anyone he perceived to be a threat to Walt?

Or, is it possible Walt's experience with whoever took him has changed from the sweet little boy we knew and it is he who does the killing?
