Replying...
Intro. You are a baby boy that was abandoned in the sea, on a small raft, and you have been out on that raft for days without food or water to drink, you are only a few months old and you have a old scar across your chest too...and you were heading towards Tracy Island because of the current and that's when John while in space picked up the disturbance.
