Ghost said:I wouldnt say anything is obvious at this point, how could a teenage girl and a time travelling AI fit into the storyline of Halo 2?
Same model?
A few things. First, the latest wave of sound files occur in the immidiate aftermath of the glassing of Reach - much discussion about that. Cleary this ties into the Halo storyline.
Second, the backstory of several characters fits into the methodology used by Oni to create the Spartans. Oni snatched six-year old children from around the world and all colonies, replacing them with flash clones who could not speak and came down with illnesses, dying a week later. One character discusses at length a sister who went through that exact process - suddenly became ill one night, can't speak, and dies a week later. I suspect she is one of the female Spartans we meet in the Halo books.
Last, the AI (Durga) is likely the same one which was found and taken aboard a ship, the Apacalypso. A strange AI was wreaking havok on the ship after an artifact was brought on board. It disappeared when the ship came to earth. I don't think there is any time-travel involved.
There are litterally hundreds of other ties and touchpoints to the Halo universe for those who have been following, and the ties are becoming more explicit every day.
