"Dean! Dean look! A shooting star! Did you make a wish?"
Dean was smiling softly at her "Yes, yes I did~"
Valerie turned at him "What did you wish for?"
Dean giggled "I can’t tell you!"
"Oh c’mon! We shouldn't have secrets for each other!" she said pouting
"Maybe one day I will tell you~"

My babies!!
I'm pretty sure we know what's Dean's wish~
He's too a cutie pie to not wish for Val's happiness (or just to find the courage to ask her to marry him)
