I wouldn't even know where to begin were we to have a discussion regarding the repercussions of time travel...but I am intimately familiar with the pain and distress inflicted upon certain perfectionists on our team when confronted with the bitter reality that no mortal man is infallible. He yet lives, for a mercy, but as a shadow of his former self. A man haunted by the promise of "what if." His name is John, and he is sorry.
