A theory, unlikely but let you think about it; Charon is attempting to restart the Great War and Hargrove managed to trick and manipulate the Sangheili faction Smith was part of in helping him but unknown to Hargrove and Charon, it's the Sangheili who are deceiving them.

The Aliens informed Hargrove that the Alien Temple in Season 13 contains a powerful weapon. But the problem is that they need something to reactivate the weapon and that can only be found in the Alien Temple at Sandtrap. And guess what that thing is; the Monitor that Epsilon used as a body in the Recollection series.

This was no ordinary monitor. The monitor contained an Ancient AI, that was locked up in the temple as punishment for crimes against the Alien Race that built it. Although inactive, the AI still lives. It was only reactivated when Caboose installed Epsilon inside it.

Now this is where things get crazy. What if Epsilon has somehow, unknowingly merged with the AI and all those recent headaches were just the Ancient AI slowly regaining control.

Possibiliy on the next few episodes, Charon managed to capture Church and forced him to rectivate the weapon. After he did that, the Ancient AI took his chance and possessed the Alien Weapon.

It's at this point, the Sangheili betray Hargrove and the mercenaries. The Sangheili revealed that they were just using Charon, or more prefered term, Shisno to free their God, the Great Destroyer. With his return, the Great Destroyer can restart the Great War and this time, wipe humanity out of existence.
