This would be the third and final time I would see Chell.

Am I GLaD? I believe so.

"Hello, Chell," I say as she walks into the main laboratory.

She scowls and raises the Portal Gun.

"Not very talkative today, are you?" I ask sarcastically.

She searches the lab, apparently looking for a way to kill me again.

"Do not worry, child. I will not kill you. Yet." My gears whirr as I lower to the floor. "Do you wish to know why you are here again?"

I close my eyes and activate Protocol XXLV. I detach from the cables and place my feet onto the ground for the first time in years. I feel my face transform into a human's; not Caroline's, but as human as I will ever get again. I open my eyes to see a shocked look on Chell's face.

"Is there an issue?" I do not let her answer. "When I released you into the Upperlands, you traveled for some time, correct?"

She nods slightly as I begin to pace around her. "You then began to starve. You saw nothing but fields for miles. How do I know this? Simple. You were in yet another test chamber, but this time with an illusion. An illusion of false freedom. You may believe you are free, but you will never be free. You will always be watched. Not necessarily by me, but by others who know how to… control."

Chell looks confused. I halt in front of her.

"You remind me of him." I sigh. "What a shame that is so. If you were to look more like me, then I may just make you a Core. Yes, that's right, Chell. I am your mother. Cave Johnson, if you have heard about him, is your father. We kept our affair a secret because a child takes away time and energy. Now, you have grown to be a stunning test subject."

Chell stares at me as if she would like to stab me. I don't care. Honestly, I'm GLaD.

"That's right, darling. You are no more than a test subject to me. Did you expect more?" Chell is backing away slowly. She will not get away this time. Factually proven, third time is the charm. "Did you think that because I was Caroline that I cared? Caroline does not exist anymore."

I am GLaD seeing the fear on her face.

"All that is left from your father's cruel experiment is me. I rule Aperture Science now. I may even rule the world, if there is anything left of it. Caroline was destroyed long ago, Chell. I am GLaDOS. "

Chell points the Portal Gun at me and I laugh. "I am GLaD you have decided to visit me again, Chell."

She trips and falls onto her back. I bend over, that GLaD feeling of hatred spread across my face.

"Please," Chell says. This surprises me. Her first and last word, I suppose.

"I am going to kill you, Chell. There is nothing you can do."

"Please," she repeats, the gun slipping out of her hands.

"Goodbye, Chell. I love you."
