(In Sam's dream...)
Castiel: Dean, you can't possibly eat another. That's your seventh piece.
Dean Winchester: No, it's not.
Jack: Castiel's right. I counted.
Dean Winchester: Okay, first, don't be a narc. And secondly, seven pieces is perfectly normal.
Sam Winchester: Uh, it's really not.
Dean Winchester: It's not even a whole pie.
Jack: Was he always like this?
Mary Winchester: Even as a baby. John and me, we used to call him our little piglet.
Dean Winchester: All right, I'm done.
Mary Winchester: With love.
(Sam and Mary leave the room and Dean signals Cas to send another box of pizza across the table to him)
Mary Winchester: Let me guess... she made a bad demon deal?
Bobby Singer: Opposite. She didn't make one. Lost the love of her life. Never moved on.
Mary Winchester: And Dean and Sam were never born. Bobby, I made that deal. And it- I... brought my boys a... lot of pain. But... What happened here, in your world? Sam and Dean stopped that war in mine.
Bobby Singer: Then I'd say you made the right choice.
