I always kind of got the impression that Sally and Billy had a thing going on. I forget why. Maybe they were together in some of the cards or something. Or it could just be that they both kind of look a little like they have the whole teen angsty thing going on. Like, one of them is the Sheriff's son, the other the highschool sweetheart with a bit of a bad side. ;-)
