Clark Kent:
[Clark superspeeds into Reeves Dam and pushes Lex up against the wall] She was your wife, Lex. Why did you do it?

Lex Luthor:
Now is not the time to lecture me about my marriage, Clark.

Clark Kent:
Why'd you do it? Just tell me!

Lex Luthor:
Get your hands off me!

Clark Kent:
You afraid she was gonna bring you down, or was it just too humiliating for you that she was gonna leave you? Why'd you have to kill her? Why?

Lex Luthor:
What are you talking about?

Clark Kent:
You already know. Lana is dead.

Lex Luthor:
[genuinely shocked] No.

Clark Kent:
No. You don't to need act so surprised. You're the one who killed her. You put a bomb in her car. You're the one who killed her!
