Sam and Dean took you on a case with them, the case ended up being a shifter. You and Sam found out first so immediately when Dean got back from walking the town to get information you two questioned him. Sam spoke up first pointing a silver dagger at Dean, “it’s a shifter, thats whats been killing people”

Dean looked at the dagger and put his hands up in a surrender before replying his gaze flickering between the blade and Sam, “okay that’s great so why are you pointing that at me?”

Sams gripped tightened on the blade, “you were gone for a pretty long time” Dean scoffed, “so you think i’m the shifter? there was a cute girl so i stopped didn’t know that was a crime now”

You finally spoke up from next to Sam, “prove you’re not. whats something only Dean would know?” Dean eyes moved to you, “would the shifter know your favorite colors yellow because you watched the movie beauty and the beast like a thousand times when we were kids at Bobby’s?”

Sam lowered his dagger as Dean kept talking, Deans gaze not leaving your face, “Or that sometimes when you have nightmares i’d let you come lay with me? or or that you’re favorite flower is Yellow roses from beauty and the beast?”
