okay so both cas and dean were born girls and it was an au fic where they were both at a bar or something for either a halloween or some sort of costume party. cas was dressed up as an angel and dean if i remember correctly didn't dress up at all. they meet that night at the party and i remember they make a date to get burgers at the end. im pretty sure cas was girl!sam's friend or roommate. any help would be appreciated :)
