: Sept 22: John, Cortana and the other survivors of the Pillar of Autumn hijack
: the Ascendant Justice. Cortana takes control of the ship, during which she
: encounters a hostile Covenant AI. Once they have the ship, the humans fly
: it to Reach to look for survivors.

: Sept 7: Due to shenanigans from the Forerunner crystal on Reach, the
: Ascendant Justice arrives at Reach two weeks earlier than when they left.
: While John and co rescue Blue Team and their pals, Cortana grapples with
: the Covenant AI of the Justice. She kills it and discovers its code
: appears to have been copied over and over for seemingly no reason, and
: that its code patterns are "maddeningly familiar". She then gets
: the idea to make a copy of herself using the Covenant AI's code, though it
: has slight imperfections from the process.

: Sept 13: Blue Team and the captured Ascendant Justice initiate Operation:
: FIRST STRIKE. They board and attack the Unyielding Hierophant, which is
: accompanied by an enormous Covenant escort fleet. Cortana's copy comes
: with John and it makes a slightly imperfect copy of itself, which later on
: makes a copy of itself, which makes a copy of itself, etc, until the
: Hierophant is swarmed with scrambled Cortana copies.

: Speculation: At some point in the battle, one, maybe more, of the Cortana
: copies makes it onto the Covenant escort ships, one of which is the
: Ascendant Justice, the original that hasn't gone in time yet. By this
: point the Cortana copy has been replicated with so many imperfections that
: it doesn't even act like her anymore. The Covenant don't destroy it but
: instead repurpose it to work for them. A week later news arrives of the
: discovery of Halo, and the Ascendant Justice heads to the ring with the AI
: aboard, completing the loop.

Now that's the kind of head games I like! Is there a site or page detailing all this? Or is what you quoted pretty much the the entire lay of the land?
