   Summary

   The Visitor has arrived, and the consequences on the world have been made very clear very quickly. While sometimes entire towns can move on with their lives with mild inconvenience, other times residents of a single building aren't as lucky. This is the story of how Kris and Sam's lives have interwoven as a result.
