When faced with either having an accident or going in a diaper, Sosha chooses the diaper, but this choice ends up backfiring.

In this scene Alisha locks Sosha, who is desperate to pee, out of the bathroom. Finally, Alisha relents and lets Sosha in, but won’t allow them to use the toilet.  At their absolute limit, Sosha chooses to quickly put on a diaper, instead of risking wet pants.  Unfortunately, the diaper leaks, making a mess on the floor.
