Zoe had changed in a way that Jon didn't expect. She now looked...exactly like him! She wore his jeans and t-shirt. She had her hair cut short. In fact, she appeared to look EXACTLY like him. Even her face and body were no longer her own. She was an exact copy of him.
Jon looked down nervously to examine himself. He looked at the device in his hands. He had the same black painted nail with the polish beginning to chip that he had before. His breasts were still encased tightly in a black corset and his long black hair was still fine as well. He breathed a sigh of relief...but stopped halfway when he realized how his analysis didn't make sense.
He looked at Zoe thinking she looked like him, but he looked at himself thinking he still looked exactly like himself. However, it was clear that he and Zoe now looked nothing alike. He knew those thoughts were conflicting, but he couldn't figure out which one was wrong. He knew it was all the broken Role Exchanger's fault, but he still couldn't figure out what was correct.
He had no way to know that the Role Exchanger swapped his body with Zoe's. He could see Zoe's change because he had been holding the device, but he couldn't see his own because it was broken.
