Hayleen is immune and has marks in the skin which determine her fate. Definitely, that does not mean she wants it. In fact, she prefers the risk of spending a night in the maze before allowing it to become true. She is better off dead than living with the conscience of knowing that she is to blame for creating such a dark future. Of course, she is also the key to preventing the extinction of the human species, but it was humans that caused the Flare in the first place... they asked for it, right? Really it not depends on her if there is a total extinction of humanity or not, of that Lyn is convinced. As sure as WICKED is that it is essential to find her to fulfill her destiny and give her into the trials. Without a doubt, the powerful of this new world are fascinated with the idea of a future with those four monsters in charge and would do whatever it takes to achieve it. It is not important. They can search for her as desperately as they can that they will still have to make the trials without her. Hayleen will never end up in the maze or join them. There is no destination. It doesn't matter that the names on her skin remind her otherwise every time she looks in the mirror.
