Leah can't believe the situation she has found herself in. She's kept her diaper clean for a few days, despite the strange urge to use it. But now, during an outing to the park, she's had an accident. Worse, it wasn't just wetting herself, it was messing herself. Even worse, she went on her own, without Rita. But worst of all, she doesn't have any clothes to change into. As Leah finishes pooping, she realizes that it can get much worse.
"Oh, it looks like someone needs a change!" a voice says. Leah looks over. A young mom with a diaper bag has witnessed her. Leah blushes. She felt a log exiting her while she was on a swing, and was only able to hobble to a bush before she couldn't hold the rest of it back anymore. So her squatting behind a bush had an audience.
Before Leah can say anything, the mom lifts her dress, which Leah only just now realizes is not her more adult one, but rather one of the childish toddler ones Tina packed for her.
"Oh, wow. You weren't ready for big girl undies, were you?" the mom asks. Leah blushes even more. It's less embarrassing to let the woman think she's a toddler than to explain she's a teenager who had an accident and is wearing toddler clothes. "Don't worry, I've got a diapy in your size."
Leah, determined to pretend to be a toddler to avoid complete humiliation, says nothing as the mom lifts her and brings her into the park bathroom. The mom places her on a changing table, removes her clothes, throwing the soiled underwear away, and begins wiping her down. Leah squirms at the cold wipes, only for the mom to put a pacifier in her mouth. Reluctantly, Leah sucks on it, and before long, she's back in her dress but diapered underneath.
Clearly pleased with herself, the mom brings Leah back outside, taking her past the equipment she had been playing on earlier. Leah is deposited in the toddler and baby sandbox. She looks up at the mom, who smiles at her.
"I'll explain everything to your mommy, okay?" she says. The mom then takes a seat and begins splitting her attention between watching Leah and watching a little boy Leah's size, presumably her son.
Leah sucks on the pacifier, desperately trying to think of a way out of this.
