Dean had just got home from hunting and he was greeted by Cas, still in his cooking apron, and a small girl with wild blond hair and china doll features, Kate.
He scooped up the girl, she kissed cheek and asked, "When is Uncle Sam getting here."
"He should be here in an hour or so, Sweetie," replied Cas.
"It looks like you have been cleaning all day, ya know Sam and I lived in motels most of our lives."
"I remember and you will never do it again if I have anything to do with it."
"Cas?"
"Yes."
"I love you."
