I think I know what happened to Cortana!

Has anyone ever considered that whenever Cortana sacrificed herself to help chief shut down the composer, she got the opposite affect of the composer? The composer turns living beings into AI, maybe she, an AI, turned human.

She’d turn into some freak of nature, The Forerunners weren’t able to turn the composed back into Forerunners, I highly doubt she’s out there anyway, 1. Mantles Approach was nuked 2. Requiem fell into the sun, not much places for her to be

If 343i did that then the franchise will truly die and be buried in a coffin. That will be the worst idea and one of the worst plot twists in gaming history that nobody will be able to take the series serious anymore.

and I played Bionic Commando, where the “twist” in that game is that prospetic arms are controlled by dead people.

Just no.

Yeah now that i think about it that would be a bad idea, just something i started thinking. I mean they were aimed at earth, if im not mistaking. hmmmm… Maybe she landed on earth somewhere.

No.
Not going to happen.
End of discussion.
Cortana’s dead.

Moving on…

Don’t worry, Master Chief has a backup copy of her on his USB flash drive. I mean, everything interfaces with everything in the Haloverse it seems.

Umm. You do know Spartan Ops took place 6 months AFTER the Halo 4 campaign right? Whats to say Halo 5/6 aren’t set within this 6 month period? The space of time between the start of Halo Reach and the end of Halo 3 was only 8 months, so whats to say this isn’t the case here?

Because the unsc didnt go back to requiem until spartan ops.

^This, and there’s no evidence to show Chief was on Requiem

I haven’t written off Cortana or Diadact just yet. If Diadact somehow escaped he may have found Cortana first, solved her rampancy issues, then they realise they need each other and track down Chief near the end of Halo 5.

Given the weird and wonderfull things we’ve seen in Halo so far, I don’t think we can really rule anything out.

That doesn’t mean MC didn’t go back alone, does it? If he has “gone rogue” like people are assuming, then he wouldn’t need permission from the UNSC would he? For all we know the game will start at some point during those 6 months and end sometime just before or after Requiem is destroyed. Hell for all we know MC could have been doing things on Requiem behind the scenes during Spartan Ops, and thats what Halo 5 will be about.

So many good ideas here! I agree that the OP’s original idea won’t happen, but I do like some of the other ideas here. I think that Halsey will have a huge part in this before Halo 6 is over, and that she may be involved in somehow bringing Cortana back.

I also agree that the Didact isn’t finished in his campaign to destroy humanity, either.

Why would he look for Cortana? He’s been with her for a few months (not counting when he was in cryo) he didn’t go back to look for James or never even bothered to ask about blue team, who he grew up with, besides, the mantles approach was nuked, the Didact had enough time to escape death, Cortana didn’t, besides it would be unfair on Cortana to bring her back, you can see the pain rampancy is inflicting on her

It’s best she stay dead, it’s a wonder she didn’t succumb to the Logic Plauge

I think the key characters that will be in Halo 5/6 are:

Halsey
Mendicant Bias
Laskey
Didact
Cortana
Chief (Obviously)

Wait and see.

My guess is since Cortana could split herself up she got fragmented and MC is looking for a way to put her back together with the help of Halsey.

My thoughts exactly.

He didn’t go back/look for the other Spartans because that is what they were trained to do. And who exactly would he ask about them? I don’t think any people involved in the Spartan II program, other than Halsey, were in previous games, so hardly anybody would know.

The Mantle was nuked? You are aware what the Mantle is right? It isn’t a physical thing, its the Forerunner’s philosophy on the responsibility of preserving the diversity of species in the galaxy. So how could it be “nuked” if its not a physical object?

Whats to say that when Cortana mysteriously disappeared just before Chief spoke with the Librarian that she wasn’t backed up and repaired (or even upgraded) then transferred to another Forerunner structure or Halo ring? She modified the Chief’s DNA to make him immune to the Composer, so why isn’t Cortana being cloned and her rampancy repaired a possibility?

Here you go.

Ah. thought he was talking about the Mantle of Responsibility. OK my bad, I hold my hands up. But still doesn’t mean anything else I said is any less true/false.
