(Laurie is the pink haired o red haired? dont remember now) if its any of these two, yes, you can save them. with the pink haired one you have to have a determined skill level, and you will be able to save her.
If you want to save Laurie do this:
Go right instead of left, fight the creature with 6 legs but choose to overcome it's power
During your fight with him hesitate (you will be fine because of the fight from earlier)
Choose to destroy the weapon he is building instead of attacking him directly because he looks vulnerable
Having 28 skill or higher helps meeting the requirements to save Laurie
With this you should be able to save Laurie, I hope I've helped you
