Update: I've now fixed the problem with the Document.
The aftermath of the Island sets things in motion, and a mysterious visitor interacts with people from the past.
(Note: These characters belong to JJ Abrams, Carlton Cuse, and Damon Lindeof, and do NOT belong to me in any way, shape, or form. This is FAN FICTION and no actual spoilers about Season 6 are contained within this script. I just wrote this for fun. Enjoy!)
