the theory that Mc goes back in time is quite plausible. Alternate Slipspace travel alters time, and forerunner technology is the only way of engineering this so far. So it makes sense a large scale forerunner portal could alter time if collapsing in mid transport. If MC went so far back, he might be back at a planet during the forerunner's intial confrontation with the flood. Thus Guilty Spark's comment would make sense, because human are not forerunner (Read the books, comics, and the Iris and letters, humans are NOT forerunner), that MC had done it before. In a VERY radical thought heres what this could mean.
Note, even to me this is a remote possiblity, but if it true, I CAME UP WITH IT.
Maybe chief and cortana go back. And cortana is either labeled Mendicant Bias, or she is the second AI spoken of that helped the forerunners in the time of crisis. Or, maybe she and John find that they must aid the flood in order to make their own future happen, so cortana is MB and aids flood along with John. There are so many possibilities. Marathon is not, however how much people want it to be. The information about characters, timelines, and equipment do not match. Another fact is chief is close to or slightly over thirty. He could NOT be the person in marathon, especially with their personality difference. He could just be at Onyx, he could be at another forerunner planet, or an even better idea... due to the fall of reach references, including the one about home and grave spoken on Crow's nest,
JOHN COULD BE AT REACH.
