Aimee finally found Mary Jo...at the cost of getting trapped inside the cubbyhole alongside Mary jo's mummified corpse. While she screams for help, you hear a strange noise from inside the vents, which you go to investigate. You eventually find the source of the noises in the vents as a blond haired girl screaming at the top of her lungs

"AAAAAAAAAAAAAUUUUUUUGGGGGGGHHHH!!! HELP ME! SOMEBODY, HELP!!!!!"

She seems to be crying too, that's when you notice something in the corner that you can't quite make out, on closer inspection it appears to be someone's mummified corpse
