Lex: Look at us, Clark. I'm a product of my father's breeding. He needed an heir. But your parents chose you out of love. I'd take your family any day of the week.
Clark: Lex...do you ever miss not having a sibling? Lex: I used to - until I met you, Clark. You're closer to me than any blood brother.
Clark: I guess no matter how bad you want to, you just can't save everyone. Chloe: But it doesn't stop you from trying...does it Clark?
