Clark: Conner has... he's only half Lex, it turns out.
Lois: What? Okay, if you say the other half is Tess, I'm going to officially write that family off for good.

Lois: Are you trying to tell me that Conner is the genetic love-child of Clark Kent and Lex Luthor?
Clark: You don't have to say it like that.
