[quote=Requiem]I have one simple question. (Or statement if you will...)

How come in Halo: CE cortana reads into the covenant battle net and tells us that the covenant discovered that Halo was some sort of weapon.

THis was crazy, beacause if they knew it was a weapon then why would they believe in the great journey>?

I have a few theories for this.

1. Cortana already knew Halo was a weapon and she didn't actualy hear talk of that on the battle net.

2. The Covenant knew Halo was a weapon but then were blinded and persuaded by some very influential beings. (Prophets, or maybe even Cortana.)

3. All of the Covenant on Halo 04 died and the knowledge of it being a weapon died with them.

these are probably terrible guesses but I would really love some input

thanks,

The most likely explanation is that it is Cortana's judgment that Halo is a weapon based on communications she overhead on the battlenet-- not that the Covenant considered it so themselves, because as you've pointed out, that does not make sense.

Cortana and Keyes give us the same basic information-- that he that controls Halo controls the fate of the universe. Both Keyes and Cortana interpret this the same way-- that it is a weapon, which is correct, but they also assume the Covenant also think the same thing-- which is wrong.
