Before Madison can get a word out, you take action.
~This command applies to the three of you and not Madison. All of you now think that Madison has urinary and fecal incontinence. Ever since... Alex caused a car accident when Madison was four, resulting in her permanently losing all of her continence, and wearing diapers ever since then. You also think that she is unable to change herself, and are accustomed to any family members or close friends of the family taking care of it for her.~
"Dad! This guy is trying to get me to wear a diaper!" Madison yells.
"Sweetie, his name is Daniel, and he's trustworthy. You can let him change you." Alex says as the family pours into the room.
"...WHAT?" Madison stomps.
The three of them take notice of the dark spot on Madison's pants, and then take notice of all the panties in Madison's drawer.
"Maddie, are you... trying to use underwear again?" Amber asks, sifting her hand through some of the panties.
Alex approaches her daughter and gives her a tear-stained speech about how deeply, truly sorry she is for "not paying attention to the road and getting you hurt", and how she feels like she has failed as a mother because of it, but that Madison still needs to wear diapers, and isn't going to be getting out of them.
All it does is leave Madison confused, and infuriated that everyone is talking down to her like this. Let alone that everyone just spent five minutes staring at her while her legs get cold from the pee in her pants. She slams the bathroom door and screams for everyone to leave.
