At first when I first played it when I came out, I was dazzled by the story, then got confused. Now after awhile of thinking what if there was no weird time gap between halo 4 and 5. Except for the janis key.
- What if the cutscene in the very beginning of the game had to do something otherwise it would not have been shown at all its for our own interpretation. It shows Halsey grabbing another Cortana model and that her left arm is still present. So before the events of Spartan ops. A picture of Miranda Keys as a memory so after Halo 3. And that locke will be ordered to kill them both if Oni ever found out? Did Halsey piece Cortana back together or did she make another one? - Another point was made at the end of the campaign on legendary that the humming she made when she rebooted the Halo ring was so similar to 343 guilty spark’s humming. - If it was another Cortana, it would explain why she said “She has to wait for another transmission from her” something along those lines… She may have input Cortana in the system, that she secretly put together, while waiting for to send another transmission, may have found fragments of the old Cortana model and combined it with hers? And that Halsey may have screwed up, which is why she is panicking frantically everywhere trying to get the Master Chief back and not caring about Cortana at all. - Another thing is the way Cortana explained how she got to Genesis through a portal, she said it so quick. Like she rushed to lie to John… Which goes back to 343 guilty spark acting as Cortana, so that he can have humanity’s best weapon on his side, a reclaimer carrying Iso didact’s genos, and again the humming at the end of the legendary campaign. It just doesn’t sound like Cortana at all. - These are the 2 crazy unknown possible explanations. Just never pieced together correctly.
