Reality Editor: Butterfly Effect

Jon felt dizzy suddenly and closed his eyes. He felt like he could feel reality shifting around him...producing a great feeling of dislocation...as if he was no longer in the same place. But that made sense, if Susan never existed, neither did Sarah, and therefore, he wouldn't have come here. He opened his eyes...and Sarah was sitting across from him. "What's wrong?" She asked. He still felt disoriented. He tried to focus on her. She looked...different. He blinked a few times, focusing his eyes and his mind. Her hair was brown, she was a little less obviously busty...but it was clearly Sarah. He'd erased her mother, how was she still here? Unless she had a new mother, which would explain the change in her appearance.
