Abyss: Both heartwarming and tear jerking.
Chloe: I've forgotten almost everyone, Clark, and I'm having to fake my feelings more and more with people. Pretty soon there isn't going to be any more "I, Chloe." Just an I.Q.
- Clark carries an unconscious Chloe to the Fortress as more and more of her memory fades.
Clark: Chloe never would have gotten hurt if she wasn't trying to protect me.
Jor-El: I tried to warn you the danger in sharing your true identity.
Clark: Now that I'm taking more risks, it's even more dangerous for her. Chloe deserves a life free from the burden of my secret. When you restore her memory, I don't want her to remember anything about Krypton. Or my abilities.
Jor-El: I know this choice is not easy for you, my son. But it will be done.
Clark: You're the best friend and ally I could have had, Chloe. The truth is, you saved me more than I could have ever saved you. I'm sorry to go back to hiding the truth from you, but the best way that I know to protect you... is to let you go. (kisses her on her forehead)
- After taking her back to Smallville, Clark returns.
Clark: Jor-El. I've come here to thank you for what you've done. Chloe's a lot safer now that she doesn't remember the truth about me. I guess I'm just starting to realize how much I actually lost.
Jor-El: You made a difficult choice. I'm proud of you, Kal-El.
Jor-El: I'm here for you as well, my son.
Clark: Thank you... Father.
- Note this is the only time Clark calls Jor-El "father", he is so grateful for him saving Chloe from a Fate Worse Than Death.
