Let's diminish li'l sis

*(Based on Someone's episode)* Jon stood in the doorway and pointed the remote at Zoe. He wanted to push the plus button, but there wasn't much space between the plus and minus buttons, so he accidentally pressed the minus button instead. A beam of light went out from the device to hit his sister. She didn't seem to notice and continued to work on her homework. But Jon saw all the changes that had happened. "Oh no... I'm so sorry, Zoe." Zoe then looked at him. "Sorry about what, Jon?" Jon was horrified by what she had become. He dropped the remote. That thing was dangerous! "What is that?" asked Zoe. Jon struggled to find the words for a reply.
