Clark Kent: Jor-El died getting me on that ship. My dad died of a heart attack from the powers he took on protecting me. And now Lionel's been murdered protecting my secret.
Chloe Sullivan: They did die for you, Clark. But ultimately, they died for all of us. There was a reason those men were in your life - each of them added something to the man that you are today.
Clark Kent: How could Lex have done it? How does a son murder his own father?
Chloe Sullivan: Total absence of love. Some say that's the definition of evil.
Lex Luthor: It wasn't an accident we were in Smallville the day the meteor shower, was it? The factory was just a cover. You were really there to meet this Traveler that Veritas wanted to protect. I remember everything, Dad.
Lionel Luthor: Those are the memories of a small boy trying to cope with the trauma of a meteor shower.
Lex Luthor: A trauma brought on by his own father. My life changed forever that day. You sacrificed me for the Traveler. Why? Who is it, Dad? Who is it? Who is it?
Lionel Luthor: What if I told you now that you were the Traveler? You're right. Your life truly changed that day. I told you in the helicopter that you were destined for a great future. That's why I've been so hard on you, trained you so relentlessly. Think, Lex. Think. You have survived so many mortal injuries so many times. How else can you explain it?
Lex Luthor: Because I was trained never to accept defeat. When I get my hands on that box in Zurich, I have a feeling all my questions will be answered.
Lionel Luthor: Lex? I know how strong it is, the attraction of the dark power. But it will destroy you. I can't let you go down that terrible path. You must not open that box.
Lex Luthor: I can't open it because I need a second key. Give it to me.
[brings out his gun and shoots out the window behind Lionel]
Lex Luthor: I've swept every possible place you could've hidden it and I finally realized, there's only one person you would trust it with. Yourself.
[rips the chain around Lionel's neck with the key]
Lionel Luthor: Lex? Lex, if you open that box, if you get hold of that secret, there will be no redemption for you, no redemption. Ever.
Lex Luthor: I was raised in your shadow. Now, you're gonna die in mine. No one will even remember your name.
[Lex pushes Lionel out the window and Lionel plunges forty stories to his death]
Clark Kent: I tried to be your friend, Lex. But all you care about is power and control.
Lex Luthor: This is Smallville! Meteor freaks, alien ships, cryptic symbols! These threats are real. Someone had to take control. Someone has to protect the world.
Clark Kent: Listen to yourself, Lex. You're so caught up in your own delusions, you've lost track of reality.
Lex Luthor: Have I? Then let's talk about something you can't deny. After years of pleading with my father, showed me some compassion, he turned to you with open arms. Now what would a worldly-billionaire have in common with a simple farm boy?
Clark Kent: Maybe he just knew he could trust me.
Lex Luthor: Of course. Everyone can trust Clark Kent. You're the perfect son. So... so why did Jonathan Kent always seem so stressed? I mean, was raising the perfect son really that much work? I wonder how much of a strain it put on his heart?
Clark Kent: Are you blaming me for my father's death? Are you? You're the guilty one, Lex, not me. And this time you're going to own up to what you've done. I know you killed Lionel.
Lex Luthor: [scoffs] Who's delusional now?
