You spend the entire day transforming the people in your class. Of course, you don't just change the a-holes that mess with everyone in class, but you also change the innocent classmates, to make them more popular. At the end of the day, you return home, while you still had the TF-Note in your backpack.
As you got home, you found that your mother started cooking, while you head upstairs. Seeing that you had no homework, you decide to take a nap in your own bedroom. Of course, you decide to make sure no one breaks into your room, and steal your TF-Note, as you got it out of your own backpack, and hold onto it. Little did you know, that the same hooded stranger from the library arrived into your bedroom, and covered your mouth. You look up, and notice the stranger. "I see you have my book," the stranger says.
