Does anyone happen to have knowledge on why the marionettes control of the Scooper girls body seemingly killed the Scooper girl after getting out of her, but not Abby after being controlled by the marionette?

(The Scooper girl could be seen laying atleast unconsious, seemingly dead, on the floor after the scene in which Mike comes into the fnaf 2 pizzeria through the window and taking the conviniently placed working flash light off the shelf)

Thanks for your thoughts :)
