You came into my life, thinking you could shake me down 'cause I'm just some spoiled rich brat who needed his daddy's protection. Trust me - when I make things disappear, they stay buried.Lex
Lex: Clark...do you believe a man can fly?
Clark: Sure. In a plane.
Lex: No, I'm not talking about that. I'm talking about soaring through the clouds, with nothing but air beneath you.
Clark: People can't fly, Lex.
Lex: I did. After the accident, when my heart stopped. It was the most exhilarating two minutes of my life. I flew over Smallville, and for the first time, I didn't see a dead end. I saw a new beginning. Thanks to you, I have a second chance. We have a future, Clark, and I don't want anything to stand in the way of our friendship.
