Jon saw his family there, all sitting around the table: his mom, his sister Zoe, and his little brother Mikey. But now they and the entire room around them looked different. His mom looked ... well ... Goth. And so did Mikey. But Zoe didn't. She was wearing pink, while the others were dressed in black. And speaking of black, that was the primary color of the kitchen, and now that Jon noticed it, the rest of the house. The furniture and even the paint on the walls were black. And there were a bunch of candles and arcane items scattered around the house, as well.
And now for the first time since he crawled out of bed and came straight downstairs, Jon looked down at himself. He was wearing a torn fishnet shirt and black boxer shorts. He lifted up his hands and saw that his nails were painted black. It was pretty clear at that moment that whatever happened also happened to him.
He slowly walked to the table and sat down, wondering if this was even remotely the same family he knew. He also wondered whether that wish he made was only affecting his family, or whether it was affecting everyone across town.
