Kepler and Sylvain

"I think I can leap forward and in time uh you know however much we want," says the city of Sylvain. "He's like Cain he wanders Sylvain um and just is chronically all this stuff", she adds about her new-found friend, a historian who wants to reconnect with earth. The six survivors are led into an empty chamber where they choose between two options for their next course of action: go back to Earth or stay on Sylvain. A voice tells them that it will be difficult but not impossible as long as they don't try to kill each other while doing so. They then face off against one another before deciding which option best suits them.
