hen Steve comes back to the bathroom he see his younger sister naked and that his shirt was really big on her. She then remembered that she had to study for a test. We see where her purse was sitting is now a backpack. When she open it we see that she has a 9 th grade history book. Steve told her to go study at the table while he cleaned up the mess. We see that while she was studying that she had an accident and now is around 12 years old.
