Trivia: The phone Lana uses is a Samsung MM-A-920.
As Lana is talking to Clark in the Luthor mansion, the camera cuts between them. At one point, the background behind Lana changes from the dark wooden wall to the bright stained-glass window, without any change of position by Lana herself.
When Lex kills Dr. Langston in the church crypt, blood is spilled from the doctor's head and onto the ground. When Lex puts the corpse in the tomb, there is no blood on the ground anymore.
The "Local Girl Survives Tornado" article that Lana looks at is completely and totally wrong. Lana was on her way home after dropping Whitney off at the bus station, while everyone else was at prom, but the article says that she was on the way to a school fund raiser picnic. It then says that people at the picnic hurried to her rescue and took her to the hospital. But in that episode, Clark was the only one who knew where she was and he alone took her to the hospital.
The first time Clark sees Lana in this episode and she tells him to meet at the barn, she says "at 5", but the second time in the episode, she says "at 5 o'clock".
We see Lana getting strapped into a corset before her wedding. Although she's not noticeably showing that she's pregnant, this still wouldn't be very healthy for the baby.
Trivia: The first frame of the episode is a close-up of Lex and Lana's invitations, in which it reads: "The Marriage Ceremony uniting Ms. Lana Lang and Mr. Alexander Luthor".
Trivia: In the other episodes, Lex's car usually starts with LEX. In this episode, we see LL as the plate number.
Why would there be fog on the floor in the crypt of a church?
In the first version of the Chloe/Clark conversation in the cellar, Clark ends it with "If you don't know that, then you don't know me as well as I thought you did." In the second version, the one in which we know Lana is eavesdropping, Clark ends by saying, "If you don't know that, then you don't know me very well."
Trivia: The second time that Clark leaves Chloe in the basement as Lana looks on, there is no "whoosh" sound dubbed in. Also, the blur effect isn't added. Clark simply disappears. This is presumably to simulate how Clark normally appears when superspeeding away, as opposed to presenting it from the audience's omniscient point of view.
Lex: And today is the day you hold the most leverage?
Dr. Langston: Wire two million dollars to this account or Miss Lang will know everything.
Lex: I don't give into blackmail.
Dr. Langston: Oh, I think you will. No man sinks as low as you have if he isn't driven by desperation.
Aunt Nell: This may be the most important day of your life. What's wrong?
Lana: It's just... if there was 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?
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.
Lionel: You know Clark's secret, don't you? I've been watching you since you've 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 realize that Clark has kept up the deception for so long, right under your nose.
Lana: He was trying to protect me. And he's not going to 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, Miss Lang, if you don't honor the promise that you made to my son or I find out that you have told anyone about this conversation, I will kill Clark Kent.
Lionel: Do you remember, when you were just a little boy, I'd bring you up here to the office?
Lex: I used to pretend it was all mine to control, like I could just reach down and move all the cars, as if they were toys... pull all the strings and make people do what I wanted.
Clark: I better go.
Chloe: That's it? You filled in your damsel-in-distress quota for the day, and you're just...gonna walk away?
Clark: What am I supposed to do?
Chloe: I guess I always just figured that you'd sweep in and save the day, but you're not gonna do that, are you?
Clark: If Lana didn't wanna marry Lex, she wouldn't.
Chloe: Yeah, but Lana's not my hero, Clark -- you are. And this whole idea that you haven't told her who you really are, that you are 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: Oh, you think this is easy for me?
Chloe: I think it's easier than getting hurt. Clark, 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: (to Chloe) If you want a bottle of wine at 11:00 in the morning, go for a red.
