(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)
