Chapter 7: Who is he?

The mysterious entity watched as the trio solved more of his puzzles. "They are already at my 12th puzzle. If they manage to get here" The voice laughed at himself "What am I thinking? Even if they make it, there is no way they will be able to stop what I have in store" More sinister laughter "Maybe It's time I gave Chell a scare, and show her just who I really am"

"Oh man! I feel alive. This is so exiting!" Wheatly yells as the trio heads down the elevator

"I know. This is what I've missed" Chell smiles

"In case you both have forgotten, we are basically playthings for the glitch that took over the facility, and he wants us dead" GLaDOS reminds them

"Yeah, but with Chell's expert jumping, your ability to hack things, and my...uh..." Wheatly started

"Personality?" Chell giggles

"Yeah! With all three of those, there is no way that this glitch can stop us" Wheatly smiled

"You don't know what we're up against!" GLaDOS yelled "This thing...he is the definition of evil...he blames me for everything that happened"

"GLaDOS, please tell us. Who is he? Who is this 'Glitch?'"

"Fine...I'm sure you remember who I am-or rather who I use to be..."

"Yeah, Caroline, right?"

"Correct...but I came down with a terrible case of cancer...the doctors couldn't save me. So, my boss said he could save my mind...he could save my brain. So...he turned me into a robot AI."

"GLaDOS"

"Correct. I was thrilled, I would survive! But...he tricked me. I could never leave the facility...I was trapped here...I could never see my daughter again...my husband again..." GLaDOS sounded like she was about to cry.

"What does that have to do with this glitch?" Wheatly asked

"Well, I was enraged...I activated the Nerotoxin to get revenge on my boss for tricking me. I killed every scientist there, and when they tried to shut me down I used the Turrets, which I hacked to do my bidding." GLaDOS sighed "But...unknown to me at the time...my boss had a plan...he turned his brain into pure code and injected himself into me! After he saw what became of the lab and his workers, he decided to punish me. So, whenever I wasn't testing he would put me through excruciating pain"

"The electrocution! Like I felt!" Wheatly said "Now that you mention it...I did happen to hear a voice in my head...'Keep testing' 'Never stop' 'Punish Her' I was so confused, but my coding was working against me!"

"Which also explains why you suddenly looked to scared and sorry when you were launched into space. That code wasn't effecting you anymore" Chell said, finishing the puzzle "So...that means that the monster behind all of this..is your old boss...! That means its-" The elevator door opens and the trio enters a dark room. There was no exit, or test. There was only a screen, which turned on relieving a robotic man. The trio gasped

"Cave Johnson!?"
