Clark: I better go.
Chloe: That's it? You-you filled your damsel-in-distress quota for the day and you're just... gonna walk away?
Clark: What am I supposed do?
Chloe: I guess I always just thought that... you would sweep in and save the day but you're not gonna do that, are you?
Clark: If Lana didn't want to marry Lex, she wouldn't.
Chloe: Lana's not my hero, Clark, you are. And, this whole idea that you're still hiding who you really are, that you're giving up the one person that you totally love...
Clark: I'm protecting her.
Chloe: Good job. She's marrying a monster and trapping herself into a loveless life.
Clark: Chloe, you think this is easy for me?
Chloe: I think it's easier than getting hurt. You don't hesitate to run into a burning building or jump in front of a bullet because nothing can penetrate that iron flesh of yours. But, the one time saving Lana means putting your heart on the line, the Man of Steel is nowhere to be found.
Clark: Letting Lana go is the hardest thing I've ever had to do, Chloe. If you don't know that then you don't know me as well as I thought you did.
Clark: How'd you know Dad was the one? How'd you know he felt the same way?
Martha: I think when you're young, like you are, like we were... nothing is that simple. I know this is a really hard day for you, Clark.
Clark: You know, I can't help but wonder... if all those things I told myself... that knowing the truth about me would be too much for Lana to handle... if she knew my secret she'd be in danger. What if I just made up all those excuses because I was scared?
Martha: Then, you'd be just like the rest of us.
Clark: What do you mean?
Martha: Your father and I almost didn't get married. I broke it off after a year. We had a horrible argument and I thought I'd never see him again. You know, we came from such different worlds. Our families, the paths we were on - everything was stacked against us.
Clark: Then, why'd you get back together?
Martha: Because I... I couldn't stop thinking about him.
Clark: What if I take that risk... and Lana really is happy with Lex?
Martha: All I can tell you Clark is that, if I hadn't taken that chance, I would have lost everything that's ever meant something to me.
Lex: You know, Dad, ever since I've been with Lana, I wake up wondering, "Is today gonna be the day when she sees who I really am?" What if she doesn't show? I honestly don't know what my life is without her.
Lionel: What would you be willing to do to make sure that Lana is standing next to you at the altar this afternoon?
Lionel: Then, she will be. I promise you.
Nell Potter: I know that look. Lana... this may be the most important day of your life. What's wrong?
Lana: It's just... if there were something that you had to put past you to get on with your life and you tried every way that was fair and honest to do that and nothing worked... is it really wrong to bend the rules just once?
Nell Potter: Well, what would put those doubts to rest?
Lana: The truth.
Nell Potter: But, if you are going to promise your heart to Lex, you cannot go to that altar with anything unresolved. When it comes to protecting ourselves... we do what we have to do, Lana.
Lionel: This'll destroy Lex.
Lana: Mr. Luthor, I'm sorry but this is none of your business.
Lionel: Well, I'm making it my business. I can't let you call off the wedding.
Lana: Things have changed and it wouldn't be fair to Lex to pretend like they haven't.
Lionel: You know Clark's secret, don't you? I've been watching you since you started seeing my son and you've been getting closer and closer to finding out the shocking truth about Clark Kent. What a surprise it must have been to realise Clark has kept up the deception for so long, right under your nose.
Lana: He was trying to protect me. And, he's not gonna let you threaten me now.
Lionel: You think Clark's invincible. Not so - like every hero, he has an Achilles' heel, a weakness. I know what it is. And, I know that it could kill him.
Lana: No. You could never hurt him.
Lionel: Would you bet... Clark's life on that? I give you my word, Ms. Lang, if you don't honour the promise that you've made to my son or I find out you've told anyone about this conversation, I will kill Clark Kent.
Clark: I've loved you since the first moment I saw you. Will you marry me?
(Shelby doesn't seem impressed)
Clark: It's too corny, huh?
Clark: Tell me what he did. What did Lex do? You don't have to stay with him.
Lana: He didn't do anything. I've made my decision. I just want to be with him.
Clark: Why do you keep saying that? Lana, we should be together. I want this more than I've ever wanted anything and I know that you do, too.
Lana: I've-I've had a change of heart.
Clark: You don't mean that. Is this because of my secret? Lana, I'll tell you. I'm not like everyone else. I'm...
Lana: No, Clark, you-you have to go.
Clark: No! No... not until you look me in the eye and you tell me you'd rather spend the rest of your life with Lex Luthor instead of me.
Lana: I'm sorry, Clark. I love Lex.
Lionel: Congratulations, Son.
Lex: Thanks, Dad. And, why do I get the feeling that's not all you came to say?
Lionel: Good to see the euphoria of your wedding day hasn't tempered your cynicism.
Lex: I guess old habits die hard.
Lionel: And, apparently, some are next to impossible to kill, aren't they?
Lex: Do you sit up at night, practicing this stuff?
Lionel: How could you be so stupid? A grown man on his wedding day and you need me to come to the rescue again - you are pathetic.
Lex: I don't know what you're talking about.
Lionel: Don't play the fool with me, Lex. There's a crypt down below that has gotten a little overcrowded.
Lex: It was an accident...
Lionel: Of course it was. You don't have the guts to plan a successful murder. And, if anyone should discover that the fresh corpse downstairs happens to be that of your bride's physician, they just might stumble onto the truth about Lana's pregnancy. She's made a desperate man of you, Lex.
Lex: Okay. You win. Whatever you want, it's yours - control of LuthorCorp, 33.1...
Lionel: You don't have to worry, Lex. You'll know when it's time for me to collect.
