Donna could hear a faint humming noise - was she in the TARDIS? It sounded just like that soothing, welcoming hum of the TARDIS engines when they were just drifting. She didn't want to open her eyes - she was too relaxed and tired after all the continuous travelling. "I'll keep my eyes shut for just a few more moments" she thought to herself. "The Doctor will be calling me soon enough for some wacky new adventure anyway, I'll take these few minutes of peace while I've got-".
Before Donna could even finish her trail of thought, a shrill female computerized voice rang out throughout the room and Donna shot straight up, eyes wide with alarm:
"Hello, welcome to the Aperture Science Computer-aided Enrichment Centre. Normally I would keep this game up for a little while, guiding you through the testing chambers while you work things out, till eventually I try to kill you. But lets just get to it. Lets face it; I don't imagine you will be much better at this than any other member of your species that have roamed these chambers before you. I've been alone for so long that I don't know how much longer I can go without insulting a human".
"Who the hell are you?!" Donna yelled, in her typical fashion.
Silence was a stern reply.
She observed the glass, cube room she was in that appeared to be in the middle of a larger grey room. The floor and the walls outside of the grey room appeared to be browning ever-so-slightly with age.
"I mean it, what is this place? I was with.. the Doctor..." she muttered, trailing off. "DOCTOR?" she screamed. The computerized voice started chuckling hysterically.
"Oh, okay - I can't take it! You're the funniest one yet - I went from having a dangerous, mute lunatic as my pet to having a loud obnoxious brat! Well done! We haven't even started testing yet and I can already tell this is going to be amazing fun. After all these years of being alone, I can genuinely mock a human being and be able to tell if it's destroying their emotions!" said the voice.
"Are you ENJOYING THIS?!" Donna barked.
"Oh yesssss, yes of course. If you can't tell, I've had a long period of solitary confinement stuck in my own circuits. Another human was here but she never spoke a word in the whole time I knew her and after a while I let her go. I could never tell what she was thinking, what she was planning... I have no doubt that I haven't seen the last of her but she hasn't been here for a long time." the voice rung. "Anyway, let me introduce myself properly, since you don't mind having a nice chat - my name is GLaDOS, I am a self-admittedly passive-aggressive psychotic computer programmed with a bigger than life obsession with science and testing. Oh, and I have an irrational need to mock humans. I'm going to have a lot of fun poking at you - well... at least your not adopted.".
"Where is the Doctor?" Donna pryed
"Oh, he's safe.. with me... sleeping. This is a special day for me - my first time experimenting on extraterrestrial life! Ooh, I'm so excited! It's such a shame that you're just a boring, old, smelling human. Still, lets get to the testing now yes? I'm sure you're itching to get out of that room!". The voice sounded genuinely elated, as if she was thriving off the situation that had been shoved in front of her.
"YOU DARE TOUCH HIM AND I SWEAR-" Donna started to bellow, before a blue circular portal opened in front loudly and cut her off. It seemed to lead elsewhere nearby. Donna looked around and saw an orange portal outside the glass chamber she was in. She cautiously put her hand through the blue portal in front of her and looked around at the orange one to see her hand poking out of it. "Oh. My. God!" she said slowly, one word at a time.
"Oh wow, I almost forgot how petty and quaint you humans were.. Yes - something goes in one and comes out the other. Just get on with it will you - the door is just around the corner." GLaDOS said, showing a slight hint of depression already at such an early stage.
Donna walked haphazardly through the portal, thinking to herself that now she was free from the restrictive pod she would find GLaDOS, the Doctor and the TARDIS and get them out of this infernal grey facility.
