- Chloe Sullivan: I came here for help, not to be cut open by some Jack the Ripper wannabe!
- Curtis Knox, M.D.: I *was* Jack the Ripper.
- Lex Luthor: My apologies for keeping you waiting.
- Curtis Knox, M.D.: Mussolini once killed a conductor for not keeping a train on schedule. Fortunately, I'm infinitely more patient than Il Duce.
- Lex Luthor: Mussolini went down in defeat, doctor. I won't accept that in what we're undertaking.
- Curtis Knox, M.D.: Your powers might be far beyond those of mortal men, but you've met your match.
- Clark Kent: I won't let you kill anyone else.
- Curtis Knox, M.D.: I'd kill a thousand more to never have to be alone. You don't know the pain of living centuries watching the women you love grow old and turn to dust!
- Clark Kent: You and I are more alike than you think.
- Chloe Sullivan: And I know my inner chocoholic will never speak to me again, but... I think I'll pass...
- Curtis Knox, M.D.: Mankind's greatest advances would never have seen the light of day if had the genius minds behind them been scrutinized under a microscope.
- [pause]
- Curtis Knox, M.D.: Leave the science to me.
- Lex Luthor: Doctor, three of my patients are missing. You wouldn't happen to have any idea why someone with a brand new lease on life would suddenly disappear?
- John Jones: Your cousin's arrival cannot be taken lightly, Kal-El.
- Clark Kent: I went to see my father. He gave me the same warning. But I don't get it - she's my cousin - the only Kryptonian family I have; besides a disembodied voice from the arctic.
- Kara: I've been looking all over for Lois. Have you seen her?
- Jimmy Olsen: Uh, you'll need a telescope. New editor sent her to the city of angels to get a quote from the D.U.I. of the week.
- Kara: Bummer. You know, I heard that she snuck into a grain silo and took some videos of a spaceship. I was kind of hoping I could sneak a peek. I'm a bit of an E.T. junkie.
- Jimmy Olsen: No kidding? Me too! I used to sit in the backyard and try and pick up Martian signals on my dad's ham radio.
- Kara: Um, Martians use infrared, silly.
