After Jon barged in, Zoe looked at him immediately and said "Like, what the hell happened to my room?"
"Uh ..." Jon wasn't sure what to say. Obviously her memories had changed. If he told her that her bedroom was the way it was supposed to be and only she had changed, she might not believe him.
"Don't just stand there looking like an idiot, Jon," she said, putting her hands on her hips. "We have to find out who vandalized my bedroom."
Jon knew who the culprit was. It was the stone ... and himself. If he hadn't made that stupid wish, Zoe would still be her normal self. Although, this new Zoe could be an improvement.
