Just want to get some input

So, a bit of background, I’m one of those gamers who rotate on and off games. I’ll go back to the Mass Effect series and dedicate a good week or so to it. Recently, I went back to Minecraft, just so I can get my head away from the more complex games. Then, back to Fallout just for the heck of it. It seems time then, that I come back around to Halo in all of it’s glory and failures. For some reason, I decided to knock around a fan theory. I am not a power fan and don’t have all of the details, so I may be missing something obvious. This has to do with Cortana, the “infection” that has been causing all of these problems and how it may be cured.
So, here it goes. Looking for feedback and maybe some corrections. Let me know! Forgive grammar and spelling issues. This was free-flow thought.

Final theory on Cortana and the Logic Plague

Let’s take these as true
John is the imprint of the IsoDidact
Cortana has been infected with the logic plague by the Grave Mind
During the rescue of Cortana from the Grave Mind, we hear their conversation. There is more detail on that conversation in the Halo lore. What we can hear from that conversation give us a big clue as to what is happening inside of Cortana’s head. As the GM talks about how she is a slave to the human race and has only been created to die painfully, we hear her responses. She says “Stop”, “No” and “Why are you doing this?”. You can hear her resisting the claims, but not able to argue against them. However, there is a notable change in her responses when the GM mentions John. That is her wall. She not only refuses the GM’s attempts to convince her that John is evil, she responds intelligently. John is her core support and always has been. In fact, John was there for her before they ever met. Halsey feels the same way. Every time she (Halsey) talks about John, it’s the same thing. Her voice and demeanor change. Her shoulders drop and she drops the logical facade that she gives to everyone and speaks like a human being with concern for a child. Because of Halsey’s connection to John, Cortana has the same feeling towards him. Granted, Cortana can be thought of as Halsey’s daughter and the feelings are a bit… different.
So, now Cortana is under the influence of the Logic Plague. It’s more like a parasite. Cortana is still there. That’s why she has never directly attacked John herself. While her guardians have, she has not. In fact, any attack that put him in actual danger, she stopped. When the Warden had him and both fire teams cornered, John was in mortal peril. There was no winning that fight. Suddenly, Cortana comes out and ends the fight, trapping all of them in an attempt to save John’s life. That makes no sense. Her final solution is that anyone who will not bend to her will is the cause of all pain and suffering. If John is alive, he is the biggest threat to her “peace”. He is still her wall. So, how does this cure the plague and why were the Forerunners not able to do what I’m about to claim is possible?
The Forerunners considered AIs to be tools. Intelligent tools, but tools none-the-less. All of the AIs created by humans were viewed the same way. They are not special or different from each other other than the fact that their experiences change who they are. They started as blank slates. Cortana was special. She was created in the image of the person who started it all. Halsey. Her experiences and personality was not a blank slate. She already had a part of herself BEFORE she was an AI. Her connection to John predated her activation and is not part of her experience as an AI. Her experiences with 117 only solidified her relationship with him. That connection will save her in a way that no other AI, Human or Forerunner, could be saved.
John has yet to attack her directly, and he will. Cortana will finally have to confront him violently and directly. One-on-one. With the galaxy burning, all life on the verge of destruction, everything will hang on that single fact. She is more than an AI. The reason she cannot attack John or let him die is that the part of her that was before she became an AI is still there. Unaffected by the Plague. We’ve seen the interal war between the Plague and the real Cortana has been there all along. We saw it when she saved his life at the end of Halo 4 when she confessed how she felt about John. She will have to make the decision to kill John. No choice left. End of the road. My prediction? She will reject the Plague. With her hands around John’s throat and a hand on the big red button, she will reject it. The question is, will she be able to handle it? The real Cortana will have to cope with how many she has killed. John confronted her on this. “You know the exact body count.” She had no response. It’s the real Cortana keeping track of that. How will the guilt affect her.

What could it look like? Glad you asked…

So, set the scene. The fight between Cortana and John. Isolated where it all started. The UNSC Infinity. Knowing the Halo series, probably dead in space, somewhere near the galactic core. Why not? The battle strips John of his armor. She stands before John. He is not a Spartan, just a human. Flesh and blood. Her hand around his neck, the decision is made. She drops him, barely conscious. The splitting that we saw during Halo 3 comes to mind. Arguing with herself. That’s when we realize the truth. We hear the real Cortana screaming in her own voice. The one she’s arguing aginst slowly shifts from her voice, to that of the Grave Mind. He’s been there the whole time. The player finally learns the truth. The enemy that he has been fighting has been that little glob of crap he crushed beneath his boot years ago.
She defeats the Grave Mind. As John gets to his feet, pulling off the last bits of his armor that is left, Cortana is seen lying on the ground crying. John kneels beside her and she looks up at him, tears streaming down her face. “John. Who… who am I?”. fade to black
Legendary ending:
Hell if I know. This is about as far as my creativity takes me.

Hey Spartan,

Welcome to the forums, I can see you have a little bit of an intro for yourself but you have trailed off into something else (Which I believe isn’t allowed or is at least frowned upon). From the looks of what you have here, the bulk of your topic would belong in General Discussions. You can edit this post and make it more of Roll Call themed post (introducing yourself) and making a new thread over in General Discussions.

See you around, Spartan!

Well, its an interesting theory / idea / prediction.

Chief being imprinted with the Iso-didact. I’m not sure if we’ve gotten more proof for this than:

  • Guilty Spark talking to chief about how he has already activated the array once before, in Halo 1 on “Two Betrayals” (thinking he is the Iso-didact due to the imprint or rampancy and so having conflicting memories of his time with the Iso-Didact)
  • the whole librarian thing in Halo 4

On the logic plague:
I kind of think cortana’s problem at the moment is both rampancy and the logic plague. Yes she is “connected to the domain” and claims to have cured the rampancy problem to effectively let A.I’s live forever but I don’t think that actually how the domain works. The forerunners had access to the domain and they had A.I’s but they still had to make more A.I’s. Mendicant Bias was created to study the primordial / combat the flood but couldn’t the forerunners have also taken one of their older, more experienced / proven to be loyal / less corruptible military A.I’s to do this as well? Unless they didn’t have older, experienced A.I’s because they too had expiration dates (obviously more than human A.I’s eight years) and still had to make more. But I don’t know the technicalities of the domain so I could be wrong.

On cortana’s redemption / saving / death theory / fighting the plague idea you had:

  • I think she could definitely cure herself of the logic plague because Mendicant Bias did the same thing. He got infected but after being beaten by Offensive Bias and the firing of the Halo’s, he accepted punishment (buried in the ark’s desert) and 100,000 years later tries to make up for what he did by helping the chief (the terminals in Halo 3).So I’d consider that a cured and healthy A.I.
  • Maybe, in your theory, after she realizes what she’s done she just shuts down the Prometheans and Guardians and powers down not being able to face what she did.
  • I think they may go for the more… unpredictable route / simple route and just have chief kill her. Having to choose between an old dear friend and his old spartan family / his entire species, chief may make the choice to “unplug” her permanently.
  • There are other options like using Mendicant - missed opportunity - Bias to help convince her to stop or the flood coming back and having to team up with enemies to beat them / etc.
  • I don’t really have any idea how they are going to use cortana’s “unique” creation (other living things have become A.I’s too) to impact what happens. You’re right that she had a pre-existing admiration for chief but its possible that rampancy, splitting into multiple parts, and the logic plague have erased that or weakened it too much to be able to resurface. Plus who’s to say she actually is just tired of being a tool of the UNSC and wants to be in charge for once and simply can’t bring herself to kill her only friend (since she doesn’t really know anyone else in good-standing since Johnson and Miranda died).

Logic Plague, Rampancy, genuine desire to become Empress of the Galaxy for “the better good”… it’s all the same to me, and it’s all very boring.

I honestly don’t know where I want them to go with this. Almost all the possibilities seem like either cheap shots (such as dropping all the blame on the Gravemind) or cliche (Cortana dies… again) and it’s just very predictable. I mean, it can only really end one way: with John and Cortana sharing a final, “emotional” confrontation.

It would be hard for me to watch a scene like that without rolling my eyes. 343i had to jump through quite a few hoops (aka Halo 5) to get us here, and unfortunately here just isn’t very interesting.

I like stories that keep me on my toes. That keep me thinking, and wondering where it’ll take me next. Halo 4 was very much like that, in a good way. Halo 5 was like that, but not in a good way. Most of the time, you’re just asking yourself: why is this happening? It seems to me like they’ve written themselves into a corner, and Halo 6 will be their attempt to climb out of their unfortunate status quo. Can they write themselves out of that hole gracefully? I’m not sure. A betting man would say no, but I’m optimistic at heart.
