   Summary

   While exploring their solar system, Eridian astronauts find a strange, large ship with what appears to be a single living creature on it. New human being. They drag them on Erid and are delivered to Grace's biodome because, well, where else? after all, they had already brought one person there once, and they got along, and Savior Grace would be much less lonely surrounded by his own kind.
   The person turns out to be a woman. She looks terrible, unconscious, and why does this cause a feeling of déjà vu... When she wakes up, she is very afraid about both of them. And she's pregnant. And now Grace and Simon have to deal with this and figure it out, and they can barely even do it with their own relationship. But they're smart. They will figure it out.

   (or: the author has been living for years with the desire to comfort Anya as much as possible, and bloodymary gave her this opportunity)
