John was shocked at all of this, but the way he felt right now, he didn't want to dive into something he had no idea about or what it could do. For all he knew, it could permanently change him, brainwash him even! That was the last thing he needed, having his sister or parents come back and finding a weird computer program with some stranger they didn't know residing in their house. He'd have to tackle this thing in the morning.
John exited the program and turned off his computer, standing up. Then he realized that he wasn't the only one here, his sister could find the computer! He snatched the laptop and ran upstairs, hiding it beneath his clothes in his drawer. She wouldn't bother coming in his room for anything.
He washed up, undressed and jumped into bed. He fell asleep as his head hit the pillow.
