This episode was originaly intended to be the Season 1 finale (which is why Season 1 has 21 episodes, while season 2 has 23 episodes).
It was later decided that it would be wiser to end the season after part 1, as a cliffhanger.

John Glover joins the main cast after guest starring throughout season 1.

Lionel: I saw it...in your eyes, son. What you were thinking. Life would be so...easy...if I was out of your way.
Lex: Dad, I'm sorry.

Chloe: God. And you walked away with a small bump on your head. That's amazing, even by Smallville standards.
Lana: No, it's impossible.

Lex: I was thinking that maybe my life would be better off if I just left him to die.
Clark: You saved him, that's the important part.
Lex: No. My father won't see it that way. Forgiveness is not in his emotional lexicon. If anything, he'll probably see my saving him as a sign of weakness.
Clark: What are you going to do?
Lex: Help my friend find his dad.

Clark: Uh, Chloe? I've been wanting to apologize for leaving you at the Formal.
Chloe: Oh, didn't I tell you that leaving in the middle of a tornado to save a friend, totally gets you off the hook? Besides, I mean, I know you'd do the same thing for me.
Clark: Oh, in a heartbeat. So how can I make it up to you?
Chloe: Actually, you know, I've been thinking, it's funny how a natural disaster puts your life in perspective, but I think that it might be better if we just stayed really good friends. Anything other than that, just gets too complicated.
Clark: Uh...yeah. Yeah, I think that's a good idea.
Chloe: You do?
Clark: Yeah...yeah, uh, our friendship is so important to me, um, the last thing I'd want to do is screw it up.
Chloe: Good. Great. Perfect. I'm really glad we got that straightened out.

Pete: Listen, Chloe...it's okay to feel bummed out. Last night was supposed to be special...and it got ruined.
Chloe: It was just so close to being perfect. Ugh, listen to me, I sound so pathetic! A tornado hit, people are in real trouble and I'm upset because Clark didn't fulfill my wish-fulfillment fantasy. You must think I'm an awful person.
Pete: Yeah, you're a real monster. Come on.
