Can't gaurentee we'll stay, so Ed or Subaru-person might go back? [Ed seems to be doing some type of calculation in her Ed, most likely related to the amount of energy that would be required for such a thing. It had taken a super charged blast from the plasma canon to simply open a whole with the stone that Jet-person had found.]
Does that mean that Acu would bring Ed's replacement back? What if the new Ed does something wrong would there be two Eds here?
