Continued... You witness Chell's mother locking Chell in the Enrichment Center (to save her from the neurotoxin), and then comes the "boss battle". GLaDoS, running out of neurotoxin, surrounds herself with many forms of defense.You must bring the Morality Core from a lab to GLaDoS through all her defenses and install the Morality Core (to furthermore prevent her from flooding AS Labs with neurotoxin).After turning off the power of Glados, you install the Morality Core with the only thing available, rusty screws, next to the Memory,Curiousity, and Emotion core. Then, when you turn GLaDoS back on, some sparks hit the ASAWC and activate the Paralysis Mode. You fall to the ground, and GLaDoS, assuming you're another dead body, opens a trapdoor underneath you revealing a fire pit. The End. And of course you know the rest...
