Smith: I killed you, Mr. Anderson. I watched you die… with a certain satisfaction, I might add. Then something happened. something that I knew was impossible, but it happened anyway. You destroyed me, Mr. Anderson. After that, I understood the rules, I knew what I was supposed to do, but I didn’t. I couldn’t. I was compelled to stay, compelled to disobey. And now, here I stand because of you, Mr. Anderson. Because of you, I’m no longer an Agent of this system. Because of you, I’ve changed. I’m unplugged. A new man, so to speak. Like you, apparently, free. 
Neo: Congratulations. 
Smith: Thank you.
