The next morning, when Shade and Kate woke, Shade got to explaining how to change the virus to fit GLaDOS' intentions. "Got all that?" Shade asked after finishing his explanation on getting the virus and reprogramming it to attack the VR08 room. "Yes I do." GLaDOS said. Chell walked into the room as GLaDOS finished speaking. "I forgot to ask you your names last night." Chell said. "I'm Amy." Shade said. "And I'm Katelyn." Kate said. "I have a little sister with a similar name to that." Chell said. "Oh. where is she?" Kate asked. "I'm not sure. If she got out of the place we were at then she could be anywhere." Chell said as Shade sensed the virus getting into the VR08 mainframe and the roof shifted to a grid briefly. "What's going on?" Shade and Kate asked in fearful unison. Chell picked the two up and ran out the door as the apartment started collapsing. "This place is falling apart." Chell said as she got out of the apartment and started using portals to get away faster. "Amy, I'm scared." Kate said fearfully. "I am too Katelyn." Shade said, of course it was just an act.
"Well, well, well, looks like this little world of your's is falling apart." a dark voice said as the virus appeared, still looking like it did when Shade copied it. "Shade?" Chell asked. "Close, but no. I'm simply a virus programmed to take down VR room 08." the virus said. "VR, as in Virtual Reality." Chell said. "You're smart but not smart enough." the virus said. "Wait, if this isn't real then..." Chell said as she looked at Kate and Shade. "Oh they're real, they just don't look like that, and I see that master GLaDOS kept her promise to you... Shade." the virus said as he looked at Shade. "Wait what?"Chell asked, looking at Shade. "Sorry, but it was the only way to get you out, me and Kate here will explain when we're out." Shade said. "Yeah, we'll explain later." Kate said. "This better be important if you two are siding with GLaDOS." Chell said as the virus walked off to cause more destruction. "Hey, she made a deal with me to turn me into a little girl in this world." Shade said angrily. "You're so cute when you're mad." Chell said mockingly. "That's because the part of the deal that related to me becoming a little girl involved GLaDOS being allowed to make me as childish as possible." Shade said. "What does she have to do?" Chell asked. "GLaDOS has to stay in the human body she is in, and allow me to program her to be a bit more like the teenager that her body is." Shade said as the buildings around them began to disappear. "If she's allowing you access to her mainframe, then maybe we can stop her from killing." Chell said. "Sorry, we both silently gave our word, and when a techno-organic and a super computer do so to each other, then they aren't allowed to break it, their programming wont allow it and I know for a fact that both me and GLaDOS have the programming for that in our systems." Shade said as everyone collapsed.
Shade was the first to wake from the VR and removed his helmet. "You lied to her... why?" GLaDOS asked. "She wouldn't have stopped pestering me about completely reprogramming you if she knew that I could." Shade said as Kate woke. "That was fun... big brother." Kate said. "I can imagine." Shade said as him and Kate walked over to Chell and she awoke. "Okay, I want answers, now." Chell said. "Let's go to GLaDOS' chamber first." Shade said. "Fine, but if you try anything then I'm going to kill you." Chell said. A few minutes later, they were all siting in GLaDOS' chamber and Shade had finished explaining everything. "Wait, so you're telling me that my mother... is the very person that I've tried to kill twice." Chell said. "Yeah." Shade said. "So you're my twin brother." Chell said. "Yeah, and I'm also the one that did the first Aperture masquer." Shade said. "And our father is the one that left all those dens." Chell said." Yep, from what I've gathered. Caroline told Doug about her plan and informed him to protect us. Doug made sure that he made you think that he was just afraid of the GLaDOS activation. Caroline then paid the scientists that hated me to set up the disk that turned me into a techno-organic and made me immune to neurotoxin. After that Doug had you put Kate in stasis and prepare a testing application, then helped you into stasis before GLaDOS attacked. And lastly had me watch over you like I had in the past without giving away the truth." Shade said. "You are exactly correct, I've personally looked through my memories as a human and that was my plan." GLaDOS said. "Now, I believe you have a mainframe that needs reprogramming." Shade said. "Fine." GLaDOS, who hadn't left her human body, said. After that, Shade left the room to do his hacking.
"I guess you should stop calling me a mute lunatic and a murder now, mom." Chell said. "Yes I know. Kate, you still haven't revealed the location of the de-aging device." GLaDOS said. "Why do you need that?" Chell asked. "Revenge on that moron, being in space isn't good enough of a punishment for him, so I wish to put him in the body of a girl, then de-age the body, and finely put him or her through the child's testing tracks, the ones you woke up in first. Of course you will likely protest since you seemed to start liking him." GLaDOS said. "Are you kidding? Yes I started liking him, but I despise him for what he did and so I'm very willing to help, on one condition." Chell said. "That condition would be?" GLaDOS asked. "No more tests for any of us unless we ask for them, and absolutely no trying to kill any of us. I'll also be using that de-ageing device to get my age to match Shade's age, I also want one of those disks that Shade has." Chell said. "You said one condition, but fine. I only have the schematics of the original disk so you'll have to have your brother hack it to be like his and not control you." GLaDOS said. "I'm fine with that, Kate you want one?" Chell asked. "Umm, sure. I've been a little girl this long, and I'm use to it now." Kate said. "You can help us in any problems that occur during our vengeance in case something goes wrong. That way all of us are legends in our own ways." GLaDOS said to Kate. "Wait, where is dad?" Chell asked as Shade came back. "He's in a stasis pod last I saw of him." Shade said. "You didn't fish your hack." GLaDOS said. "I did, but your system needs to reboot before the changes take place, in other word you'll have to sleep first." Shade said. "Okay, tomorrow we get ready to retrieve that moron Wheatley." Chell said. "I have some relaxation vaults ready for the four of us." GLaDOS said.
A/N: I get the feeling that very few decide to not have Chell forgive Wheatley and instead have her side with GLaDOS in getting revenge.
