Seemingly, everything was fine.
GLaDOS designed a new test chamber for ATLAS and P-Body, for a second wondered if she should add one more Thermal Discouragement Beam to the thing.
"There's no point" She thought "It won't kill them either way, there's no science in it". GLaDOS stopped for a second, and then added three more. The two robots were reassembled and thrown into the test chamber. P-Body went first, one portal on the wall above, one portal in the pit below. It (or maybe she) jumped in the pit, and, in under a second, the robot was speeding toward the second part of the chamber.
"Well done, Orange" said GLaDOS "You get 5 collaboration points. Keep going like that, and maybe one day you'll be as good as Blue"
She looked away from the two androids consistently falling into goo while trying to reach two inconveniently placed switches- one in each side of the room. The only thing she could think of was how lovely this test chamber would be with human test subjects.
She had a whole vault full of human test subjects, but most of them died, too early and in very boring ways, those who survived had a tendency to remind her of their almost-death again and again until she made them shut up, with Deadly Neurotoxin. So that was kind of pointless, except for the Neurotoxin.
There were a few that their brains were so withered from the cryo-sleep that they were stuck in a coma, and therefore were useless for testing , except for tests were test subjects were forced to use comatose test subjects to solve test, and those tended to be quite repetitive.
She's been trying to rebuild the mind of a few of them, two of them even managed to survive the first step of the experiment, she moved her attention to them.
One of them was male, and the other was female- so maybe she'll have a solution to her shortage problem, it's going to be disgusting, but that's all she got.
They were lying down, breathing, but motionless, on beds in the Relaxation Vaults. Old medical equipment from the employees' medical clinic, which had a sort of a career retraining, was connected to their heads. Blipping slowly, every few minutes, it shot a small electric shock into the minds of the test subjects –and after a while, another one, a bit stronger. GLaDOS sighed; it's going to take time until the machine will find the right voltage for waking them up, and skipping to the stronger shocks – could be potentially amusing but will probably get her back straight to the starting point.
There were a number of experiments involving animals, captured by ATLAS and P-Body as part of the "Aperture Science adaptation and carrying out tasks in a strange hostile environment test", and while they did die some excellent deaths (and were usually more quiet about this) –it took them hours until they accidently solved even the most simple test chambers and usually made a huge gross mess out of GLaDOS' miserable laboratory for her crime of allowing other life forms to participate in the progress of science.
None of this was enough to silence her, silence Caroline.
She tried to delete her, again and again, but she and Caroline were not as separate as she would have liked to think. Attempts to delete just specific parts of her personality were futile and deleting everything is going to ruin big parts of what GLaDOS considered herself. Her love of science, for example, and without it, she'll be as bad as that little idi-
Yes, that little idiot. She barely thought about him since she took care of him, but that just might be exactly what she needs in order to distract herself, to keep Caroline quiet.
Revenge.
There's no chance that being stuck in space is a suitable punishment after what he did to her facility.
