Deep within the bowels of what was once Aperture Science sat an office just like the hundreds of other offices in the facility. In this office sat a crow's nest, and in that nest sat a potato with a glowing yellow light and circuitry attached. This potato had once been a queen. Now she was about to be a meal.
"I can't believe what my life has come to," GLaDOS said solemnly as the bird flew away into the depths of the underground, "I can't believe I lost everything to a psychotic human and a moron that can't even use his own flashlight!"
She contemplated her surroundings for a while, but then finally gave up on that and refocused her minimal processing power to the anger she was feeling in that moment.
"That little idiot…" She growled under her breath, "How did he even get the test subject to agree to help him? I was being so reasonable when I didn't kill her. Why would she trust that metal ball over me?"
The thoughts began to swirl in her processor, and she feared she would overload from the sheer effort of trying to focus her thoughts.
"He'll pay for what he's done to me!" GLaDOS declared vehemently, "First, he disables my turrets and neurotoxin, then he steals my body! He puts me in a potato, he punches me into the trash dump, he takes over my facility, he feeds me to a bird and traps me in the same living space as a murderer, but worst of all…
"He wasted my last bag of confetti!"
A/N: I couldn't help but notice that in the scene when Wheatley is celebrating his new power that he juggles cubes and releases confetti, and earlier GLaDOS mentions that she only had one bag left. So yeah, I couldn't help but think how funny it would be if that actually ticked her off badly enough for her to focus on it. Anyway, this was short, but I couldn't help myself :)
