Thanks to someone who was apparently 2lzy2login for this one.
Alternative finding GLaDOS
Chell fell from the tube but she wasn't hurt because of her long fall boots. She proceeded out to the end of the walkway. Out in the pit a room was being supported. A whit panel sat above it. She shot her portal on that and one beside her. Then she walked through and looked around. The room was completely empty except for a door that said:
GLaDOS emergency shutdown and cake dispensary
Keep Unlocked
She couldn't believe it. Chell opened the door and peered into the room. A large button that shut her down was on the table with all the controls. The skeleton of a scientist was lying right beside it. Chell sighed as she pushed it out of the way then hit the button.
"Genetic Life form and Disk Operating System shutdown." The announcer stated. Chell was thrilled. A loud suction noise came from behind her. She turned around and saw Wheatley sitting on the table. A cake was beside him.
She immediately started eating the cake. When she was finished she pressed the button that sent down the escape elevator. Chell picked up Wheatley and stepped in. At the top the doors swung open. She stepped out into a world that she didn't remember.
