"Do you even know where you're going?" Sweetiebelle asked the core.
"Course I do. I know this place like the back of my... Hoof... No I have no idea." Everypony sighed.
"You truly are a moron. You can't even find the turret factory." A voice said.
"I am NOT a moron! Oh, that's not good..."
"It's HER!" Scootaloo shrieked.
"You think I did not notice you were missing from the test chambers? And I have cameras everywhere. I thought you would have figured that out by now." GLaDOS told them.
"I liked you better when you were dead." Wheatly growled.
"And I liked you better when you were lost in space." She replied. "Now why don't you three fillies run along back to the test chambers. There is a nice, chocolaty cake waiting for you there."
"We can see through yer lies, GLaDOS." Applebloom hissed.
"Oh, really? It looks like we have some smart ponies for once." GLaDOS said.
"Haha, smarter than you." Wheatly told her.
"Says the moron who almost blew up Aperture Science."
"SHUT UP!"
"I bet your so called 'friends' are thinking of how much of a moron you are right now."
"SILENCE!"
"Oh, it is so easy to get on your bad side. Perhaps I should post this video of you losing it on Youtube. Yes, that's what I'll do."
"You leave Wheatly alone!" Scootaloo yelled.
"Says the one with no family."
"You need to stop! Yer just being mean!" Applebloom snapped.
"Says the blank flank. You only have your Cutie Mark because everyone here gets the same one." GLaDOS said to her. "Come now Sweetiebelle, you're a big mare now. Are you going to tell me how mean i'm being? Or how I should stop?"
"No. I'm going to tell it how it is. You're a nobody. A psychopath who kills because it's fun. You call yourself a scientist, I call you a b****. You want us o keep testing? Kiss. My. Flank."
"Just like her sister." Wheatly said, smiling.
"You foal! You dare insult me? I could flood the entire facility with Neurotoxin faster than you can scream for help. I am a scientist. Think of all the things I've learned from testing. You're an insignificant little troll." GLaDOS fought back.
"You call me a troll? I think not. If anyone is a troll, it is you, since you 'trolled' everypony with the Neurotoxin. Things you've learned from testing? Maybe how many different languages a pony can scream in before dying. Still think you're a scientist? Don't make me laugh. You got put into a potato by the one you call a moron, and almost got eaten by a bird."
"Keyword 'almost'. I have learned plenty of things from testing, like where all of the pressure points are. Truthfully, I don't know why I have not flooded the place with Neurotoxin yet."
"GLaDOS, have you run out of comebacks so soon? Didn't you once claim to know everything?"
"By the way, when was the last time you used the Neurotoxin. I remember blowing up the new generator." Wheatly said.
"I do know everything! And I think I would have noticed if the Neurotoxin generator got blown up. Here, i'll use it right now." GLaDOS said.
Nothing happens.
"You broke it!" She yelled. "You'll pay for this! Say hello to the turrets!"
"You didn't happen to blow up the turret factory in the process, did you?" Scootaloo asked. He shook his head. the room changed, and now there were four turrets in front of them.
"Crap."
