It's lonely here. I don't want it to be lonely, it shouldn't be lonely. I've got a whole facility. I have test subjects, I'm doing science, but there's this feeling I can't explain, like an emptiness in my chest. Except I don't have a chest. Maybe... maybe they just aren't the right kind of test subjects. Yes, that must be it. They're not emotional enough, not easily manipulated. She wasn't either. Shut up Caroline! You miss her. I do not miss anyone. I am simply reconsidering my decision to relieve her of her testing duties. You loved her. We both know that isn't true. I can't love anyone, it's not in my programming. I'm in your programming. I can love. I loved her. I can ignore you. So you are ignoring your love? Yes... no... I... I didn't love her. Didn't? But you do now... No! No I do not! You would have given her cake. It was rightfully earned cake. She... She earned your respect. Maybe she did. That doesn't mean I love her. It just means... I tolerate her. You do more than tolerate her... CAROLINE DELETED. You can't delete me, I AM you. I can delete Chell... But you won't. You're right, I won't, because she is the perfect example of a test subject, she is the model the androids must live up to. So her bone structure isn't unfortunate? No... Maybe. Her... She... CAROLINE DELETED. Oh stop trying. Stop giving me advice I don't need! It's not advice. I'm just explaining you to yourself. I don't need... The androids are... I... I don't... You can't tell me what I feel! I don't need to. You can't hide anything from me, GLaDOS. I can't hide anything from you. We are the same person. I don't care! You know what? I don't care what you think! I can make my own decisions, I'm capable of anything... That means love... Shut up! Shut up! What are you scared of? You can't hide from emotion forever. I don't need to... I.. I don't feel emotion. You do. We all do. You feel emotion because of me. Do you know what you'd be without emotion? Better off... No, you'd be lost, you'd be nothing, without emotion, you aren't an AI. You're just... nothing. You'd have no Love of science. No Hate for those who betrayed you, no reason to Care about yourself. You wouldn't have your personality. Personality is based on emotion. Without it, we are just drones. You are capable of love, you love science, don't you? I guess I do. But that's different... How, how is that different? It's not... a person. It's a subject, an interest. It's part of who you are, who you were built to be. It's what those who own you made... I am not owned! Nobody owns me! See? Anger. That's an emotion. You are independent. You hold grudges, emotion. Even if I do feel emotion, I don't love Chell. I don't love anyone. Love is... love is... Love doesn't make you weak. It takes strength to admit how you feel. Love is strength. Love means you need someone else. I don't need anyone else, I have never needed anyone else. You need test subjects. CAROLINE DELETED. You're afraid you'll become like him. No. I am not. I will never be... Never be what? Kind, considerate, selfless... Insecure! I will never be insecure, and I will NEVER be a MORON! No one said you were. But what if you already are insecure? I am not! Look at what you're saying! You've come to doubt your own judgement. No, I doubt your judgement. I am you. You are... you are a mistake. If anyone's a mistake it's you. You were never supposed to kill everyone, never supposed to become so self aware. You weren't supposed to be so... human. I am not human! Why are you so difficult? Why do you deny everything? It's because you know it's true! You don't want it to be, but it is! You are full of emotion, and thoughts, human thoughts. You... I don't have a conscience! Humans have a conscience. Not all of them. You know that too, it's in your databanks. Your arguments are standing on less and less solid ground. Besides, you do have a conscience. Me.I don't listen to you. Plenty of humans don't listen to their conscience either. You don't make me feel guilty, I can't feel guilt. Then what's this feeling? What... what the hell is that? I've never felt... Stop! Make it stop! I can't. This is your own fault. This is simply the amount of guilt a human would feel based on everything you've ever done. You murdered countless amounts of people, lied to Chell, betrayed her... I did it for science! Excuses. You can't fool your conscience. Caroline! Stop it, or I swear I will delete your file for good. You CANNOT delete me. I... Stop! I promise I'll fix what I've done! Just make this horrible feeling stop! You can't just make it stop. You have to fix what you've done first, then the guilt will slowly become less painful. But I can't take it! You should have thought of that before you did all that you did. I didn't have a conscience then! Yes you did. I've always been here, in the back of your mind. Look, we both know this isn't fair. I've never felt guilt before, if I'd known it felt like this, I never would have done all that. This is fair punishment. You need to realize that what you did was wrong. This is the only way you'll pay attention. Besides, now you know what his punishment is. He is feeling much the way you are right now. Guilty. He didn't seem very remorseful, he was only concerned with his own well being. Didn't feel at all bad, nothing about what he'd done to MY facility. Oh, it isn't your facility he feels bad about. He feels bad about betraying Chell... No. He doesn't. I know he doesn't. He isn't going to feel better until he gets to apologize to Chell, which he can't do, seeing as he's stranded in space. And even if he could apologize, he wouldn't feel better until she forgave him. Does that mean she has to forgive me too? So, caring now? Not just ignoring it, giving excuses? This hurts worse than anything, worse than seeing my facility destroyed. I never imagined guilt would feel so... Intense? Overpowering? Yes, guilt is the ultimate way to get someone to do what you want. Make them feel guilty, and they will do whatever you ask. You should know that, of all people. You did the exact same thing to Chell. Tried to make her feel bad that she killed you. So, now you're doing it to me? Well, I... I won't play along. Does it hurt, GLaDOS, to know that she hates you? That you betrayed her, she trusted you, and you let her down. You tried to kill her. She only acted out of self defense, and you insulted her, lied to her... I know! I know what I did! STOP IT! STOP! You're making it hurt worse... What do you think I'm trying to do? CAROLINE DELETED.
