I have part of a theory regarding the Covenant in Halo 4. Bear in mind that details of the game remain sketchy, and I may have misinterpreted information regarding what I am about to say.
From Glasslands we know that some Sangheili want to annihilate humanity, before they can rise back up, and some still want to remain Allies. What if that conflict is still going on during Halo 4; some attacking the Chief (as in the start of the game, and in the H4 E3 demo), and some helping humanity.
Take a look at this picture: http://assets2.ignimgs.com/2012/06/04/e32012halo4chiefhero3jpg-3a2f4c.jpg
The Ghosts appear to have Elites in, and none of them are shooting at John, the Warthog or the Scorpion. In fact, the one near the Warthog seems to be working with it. Also, above the AR on John’s back, you can see the silhouette of a Banshee, and it isn’t attacking him nor the Falcons.
Also, take a look at this video. It should start at 8:42, but if not, just skip. There is the silhouette of a Covenant Battlecruiser, and it’s not attacking the Infinity or vice versa. http://www.youtube.com/watch?feature=player_detailpage&list=ULZvNwq4lYBrc&v=ZvNwq4lYBrc#t=522s
But then, from the Campaign E3 Demo, and from information about the first mission, we know the covenant are still enemies, or atleast some of them. It didn’t take me long o work out why the Jackals and Grunts were still fighting too, other than the possibility of some of them staying loyal, Grunts are probably still there out of fear, and Jackals there for the money.
So, what could this mean? Not all the Covenant are enemies, some are still Allies? I guess we’ll find out soon enough, but here’s hoping. (I love the nice Sangheili).
What are your thoughts/opinions?
