Fern is proving to be somewhat resistant to the regression therapy Doctor Kat has deemed necessary for her. Luckily, or perhaps unluckily for Fern, Kat has decided to use some simple hypnosis to get past Fern's resistance. Instead of trying to cause regression with the hypnosis itself, Kat is implanting a new behavior in Fern's mind; any time Fern thinks of arguing, struggling, fighting back, or any other kind of resistance to her therapy, she'll be overcome by the urge to suck her thumb instead. This makes everything much easier for Doctor Kat as she undresses and diapers her newly compliant patient. Fern doesn't want to be diapered and infantilized, but she can't seem to do anything to stop it from happening. The more upset she gets, the more her thumb keeps finding its way into her pouting mouth.
