You'd grown up with the boys, since Dean and Sam had begged their father to keep you. You were their Christmas present that year...and the next. John knew he could hardly afford to keep his own kids, but he just couldn't help it when he had saved you from that monster. Maybe this was his chance to finally do right. You were just a baby when you got saved, but as you grew up, they had started to realize that John was a hell of a lot nicer to you than he was to them

He expected dean to watch over you and Sam, and if he didn't, he'd yell at him. But dean didn't mind. It was his job, taking care of you two. You were all very tight knit. You hardly went twenty minutes without being together.
