"A slut is someone who has sex with a bunch of guys."
"Then I guess she's a ... slut. Really, Jon. I don't know where you come up with these strange words. Everyone woman in the world was made to be like this. You're acting like this is all foreign to you."
"It is."
"Huh?"
"Boy, if Dad could be here to see this."
"You know your dad? When did this happen?"
"What? My dad. He's your dad too, Zoe."
"Jon, you must have hit your head."
"What do you mean?"
"Our dads were anonymous donors. So you have a different dad than me."
"Anonymous?" Then Jon saw that Zoe didn't look different just because she wasn't a Goth anymore, but because she wasn't even the same person anymore. That's also why she was older than him. The only thing that was the same was that she was a girl and her name was Zoe.
"This can't be ... they were married."
"Married? Oh, you mean a union. No way. Mom would never do that."
"What? Why not?"
"It's so ... well ... distasteful."
Marriage is distasteful? Jon thought.
