Lizzie knocked on Eric's door and kept on knocking. "Eric, open up! I was serious before! That computer is dangerous! Eric!"
Suddenly, the door opened and to Lizzie's surprise, the person standing in front of her wasn't Eric, but rather a girl that looked like she could have been her older sister.
"Lizzie, would you stop yelling out here? And who is this Eric guy you're talking about? Is he your boyfriend or something?" the girl asked.
Lizzie's eyes went wide, realizing what must have happened. Eric used the computer to turn himself into a girl version of himself. But since Eric wasn't the user (Lizzie would always be the user, even if she wasn't the one using the computer), he (or rather she now) didn't notice that anything was different. She actually believed that she was supposed to be a girl!
