About 20 minutes in, Martha says, "One more district, and you'll have a new commute to Topeka." Since Jonathan is running for a state senate position, he only has one district to win total. One would hope that by election night Martha would know this much about the race her husband is in.
Trivia: The funeral scene makes an allusion to the first season episode, "Crush" funeral scene. Both have a bad weather (one is raining and the other is snowing) and in both scenes the characters are bidding farewell to Lana's boyfriend's father. And both finish with Clark alone in the graveyard.
When Clark saw his dad stumbling while holding his chest, why didn't he rush him to the hospital? With his speed he might have been able to save him, but he just stayed and watched him die.
Lex tells Lana that she's lucky she never had a father to endure. Lex is pretty familiar with her background, but he forgets that Lana did have her biological father Henry Small for a while.
Despite Clark's strict (and desperate) instructions for Chloe to keep a careful eye on Lana, when they get to the party the first thing Chloe does is...talk to Clark while Lana wanders off.
Before Clark proposes to Lana, he shows her a lump of coal. Then he super-squeezes it until it is turned into a beautifully cut diamond. Diamonds are indeed created when carbon deposits are subjected to extreme pressure over time but they don't come out of the ground perfectly cut. The stones are uncut when they are mined. Diamond cutters do the cutting and polishing. While Clark could have indeed super-squeezed the coal into a diamond, it should have become an uncut stone, not a cut one.
The second time Lex throws his drink into the fireplace, you can clearly see that all of the liquid splatters out of the glass before it ever reaches the hearth. But when the glass breaks in the fire, it still flames up as if the glass had been full of alcohol.
When Lana has her accident, she is thrown clear of her car. But earlier in the scene, she can clearly be seen wearing her seat belt. The seat restraint would have kept her inside the vehicle, even after a roll-over. She should have still been inside the vehicle when Clark finds her.
Chloe: Clark, if Lana cares about you as much as I know she does, I seriously doubt anything's gonna change.
Clark: One thing might. I haven't gotten my answer yet... (pauses nervously) I asked her to marry me.
Chloe: Wow... Well, that one wasn't on the Doppler! Not even a blip!
Clark: I know what you're gonna say. That we're too young, there's a reason I hadn't told her before, that there's too much at stake...
Chloe: That's funny, because what I was actually gonna say is there are very few people out there who really know what they want...and are willing to risk everything for it.
Clark: (about Jonathan) I just don't know how I'm supposed to be the man he wanted me to be... without him here.
Martha: You're his son. You know what's right and wrong. Whether your father is here with us or not... you're a man he's proud of. A man he could look up to, and something tells me he won't be the only one.
Martha: Clark, I know you're blaming yourself, but this was not your fault.
Clark: How can you say that? I went back to save Lana... and now Dad's gone.
Martha: Do you think you could've chosen between them if you'd had the chance?
Jonathan: So, why don't you come over here and face me, you son of a bitch.
Lionel: Oh, perhaps a few lessons in tact...Senator. Now that you're gonna be in the public eye...
Jonathan: Why don't you just cut the crap, Luthor. Sure, I know my campaign accepted funds from you, but I also know I'm gonna pay 'em all back so I won't owe you a thing.
Lionel: I wonder how far that virtuous stance will get you once you're in, uh, office.
Jonathan: I just want to make sure you understand you don't have a puppet here.
Lionel: I should hope not. I didn't put my financial and political clout behind a candidate who would be anyone's...puppet. I envision this rather as a, uh...a partnership.
Jonathan: The day you and I become partners will be the day...
Lionel: (interrupting) Careful, careful, careful, Senator. Don't forget, you and I have a, uh, common interest. One that, uh, (takes out a photograph) both of us would, uh, protect with our lives. I have nothing but respect for a man who would deliberately hurl himself into the spotlight with such a dangerous secret that must stay hidden.
Clark: There has to be a way! There has to be a way, to... to fix this! Please!
Jor-El: There is one trial you have yet to experience. But, you must heed my warning. The tide of fate is impossible to stop. Even if you are able to alter one course of events, the universe will find a balance. There is only one crystal. Decide carefully.
Clark: I have to save her.
Martha: One more district and you'll have a new commute to Topeka.
Jonathan: Whatever the outcome, sweetheart, the only victory that's ever changed my life was when I won your heart.
Chloe: You told Lana your secret?
Chloe: Wow... umm, okay. God, and after all those years of me yanking on your closet door, what's the real reason for this coming-out party?
Clark: It was only a matter of weeks before she broke it off.
Chloe: But... you guys are like meant for each other, you're like Kansas's version of Ken and Barbie, except, they broke up, apparently, which is kind of weird.
Lois: Okay, spill it.
Lana: You know, it's nothing.
Lois: Three guesses: tall, dark and bumbling.
Lana: It's just, um... Okay, what would you do if you thought you knew someone really well and...it turns out that there's, um, there's this whole other side to them.
Lois: Well, that depends, are we in arms dealer territory or are we talking The Crying Game?
Lana: Nothing like that.
Lois: Then I guess the question is, does it change the way you feel about him?
Jonathan: I guess it's just... hard looking over at your son and realizing you're talking to a man. A man who doesn't need his father's advice anymore.
Clark: I'm always gonna need you, Dad.
Lana: How many times have you been there when I didn't know it, saving me?
Clark: It doesn't matter, Lana. I couldn't let anything happen to you.
Lana: And no one knew?
Clark: There were so many days I wanted to tell you.
Lana: What makes today any different?
Clark: I want you to know who I really am. (he forges a diamond from a lump of coal, sets it in a gold band with his heat vision, then gets down on one knee) Will you marry me?
Jonathan: (to Lionel) We can withstand anything you bring down on us...because we have each other. That's what will always separate the Kents from the Luthors.
Lana: When did you start caring what people think of you?
Lex: Since I was branded at birth with the sins of my father.
Lex: Probably shouldn't have called. Shouldn't do a lot of things, but I, uh, seem to do them anyway.
Clark: (after confessing his secret) Do I look different to you now?
Lana: Clark, you look like the same handsome guy I've always known.
Clark: Handsome as in "I wanna spend the rest of my life with you" or handsome as in "I'm gonna let you down easy"?
Lana: As in "Yes, Clark, I will marry you."
Martha: A heart beats only so many times in a life. Your father used his more than anyone I know.
Jor-El: Your powers on Earth may seem extraordinary, Kal-El, but we are not gods.
Clark: (to Lana) When you asked me if I believed in life on other planets, you had no idea how ironic that question was.
Lana: What could be worse than losing the person that you love?
Clark: I've lived this day before. I kind of went back in time.
Chloe: Right. What'd you do, spin the Earth backwards on its axis?
(his last line)
Jonathan: (to Lionel) Now, why don't you get the hell off my property?
Injoke: When Chloe asks if Clark spun the Earth backward on its axis, it's a reference to Superman reversing time by doing roughly the same thing, in Superman: The Movie.
Injoke: Clark's squeezing a lump of coal until it becomes a diamond is reminiscent of a similar scene in Superman III, when, as Superman, he pauses to make a diamond while recommending Gus Gorman for a job at a coal mine. As Clark, he later presents this diamond to Lana, telling her it's a gift from Superman.
International Air Dates:
The Netherlands: April 28, 2007 on Veronica
New Zealand: April 20, 2007 on TV2
On the DVD there is a deleted scene that shows Clark taking the dead Jonathan to the Fortress of Solitude and begging Jor-El for help. But there is no help - the Fortress is unlit, no voice of Jor-El and Clark has to say sorry to his father for not being able to help.
Depending on the time of day this episode is broadcast, if it is late enough, you see Lana being thrown about inside the car and her battered body lying outside the car as Clark kneels next to her. Otherwise, if it is shown earlier in the day, all this is cut out and you simply see blood on Clark's hands as he hugs his father.
In the commercial for this episode that aired right before the episode started, it showed Jonathan pinned up against a post by Lionel in the Kent barn. Lionel then punches Jonathan in the face. For some reason, in the actual episode, this scene was cut out and only showed Jonathan punch Lionel.
Music: James Blunt - "You're Beautiful", Peter Gabriel - "I Grieve"
Chloe: So how did she take the whole "E.T. phone home" thing?
This alludes to a famous line from the movie E.T., which is about an alien from outer space, which relates to Clark because he too is from outer space.
Lois: ...or are we talking The Crying Game?
Referencing the 1992 movie with a twist ending revolving around the identity of the character Dil, played by Jaye Davidson.
Chloe: All right, McFly, do you want to start with how or why?
This is a reference to Marty McFly, the character Michael J. Fox played in the Back to the Future movies of the late eighties. In that series, Marty McFly was a teenager who traveled back in time with his scientist friend Doctor Emmett Brown who built a time machine out of a Delorean.
