John and Stephen follow Liz into hyperspace, where they manage to rescue her and return her to the lab. Convinced of their story, she agrees to help them investigate the paintings, which seem to induce violence in those around them.

During solo flights in John's glider, Mike's mind connects strongly with an emerging Tomorrow Person, a sacrificial priestess in an Asian temple.
