[quote]t the end of halo 2, four hunters sided with the arbiter, what happened to make the hunters go back to the covenant (loyalists?) Were these four hunters just rebellious?[/quote]There were others like them. However the majority stuck with the loyalists. I assume they stayed with the Sangheili out of a sense of comradery. [quote]Do you think the forerunners would team up with humans? (General truce or just to deal with the flood.)[/quote]Now? I think so. [quote]Would the covenant storm faction on halo 4 recruit brutes? (Assuming not because elites.)[/quote]I don't think they would actively, no. However, there still is the chance of some Brutes staying loyal to the Sangheili in the Covenant Remnant.

Hang on a second Admirals. Everything I've ever seen on it says that the majority of Mgalekgolo sided with the Separatists (Swords Of Sanghelios) against the Loyalists.

Nope.

Give me a source then where it says the majority sided with the Loyalists.

Broken Circle, second half of the book (it's in my dorm room).
