Merry late Christmas! As for the story, I was thinking that a spoiled teen aged girl would come in for a surgery/procedure/treatment. She is then either forced into diapers because of her condition or her bratty attitude. When she complains and tries to take it of Carla loses it, tells her what a spoiled baby she's been, and teaches her a lesson by forcing her to be a TB. If you don't get what I'm talkin' about chck this out
