His sister opened the door to greet him and the imp greeted her in his own fashion.
John frowned at the imp, as he looked back and saw his dazed sister, now wearing a bodysuit of rainbow striped from the neck to her wrists and all the way to her sneakers. Her original outfit was on top but her new mind filled with rainbow fashions.
"Alright how do I stop this?" He asked the imp.
"I don't have to tell you." The imp replied.
"What?" He said.
"I. Don't. Have. To. Tell. You." And then its eyes glowed and Carry glowed brightly with light and was dressed in the same bodysuit made from socks material.
"I must wear rainbow socks." She said, eyes now glowing with rainbow spirals.
"Its mine all mine." The imp said. "You stupid human!"
John ran from the building. His lab on campus ...maybe something would help him figure out what went wrong.
The imp flew after him. As he approached campus he saw a server outside a restaurant shift into wear rainbow socks to her neck. Followed by a customer at the table.
