Halo 5 - Legendary Ending - Cortana's Song Origin

[@MartinSmithInterfaces]

Its Debussy. A song called Preludes No. 4. He is a concert pianist that Dr Halsey enjoys listening to when she works. Its only logical that Cortana would like it to. Being called Prelude should be taken literally. The definition of prelude is "an action or event serving as an introduction to something more impprtant". Played at the Prologue of Halo 5, were Cortanas creation is detailed, preluding what she is to become. Played at the Epilogue of Halo 5, where the noe corrupted Cortana takes posession of a Halo Ring, preluding to the more important events of Halo 6. Simple.

Debussy is the composer, not the pianist. But otherwise correct. Full title of the piece is Preludes Book 1, No. 4 "Les sons et les parfums tournent dans l'air du soir" if you're curious. It's gorgeous

[@joesomebody4571]

I had heard an interesting rumor/theory that cortana isn't really cortana, its guilty spark.

[@Vipe_Strike_92]

That could make some sense. Seing as Guilty Spark hates Chief it's possible that it's some sort of ploy to get back at him for what he did to his instalation(s). However it doesn't explain why he would be so interested in the Infinity if it really is him

[@BTNH515]

Joe Somebody No. all Guilty Sparks had a Different Purpose. And Cortana was Cloned from Halsey. Guilty sparks Were Not Man Made

[@BTNH515]

Joe Somebody Cortana And GuiltyS are similar A.i's. but not the Same

[@thejag4770]

Joe Somebody There are multiple possibility's, could be the separation, could be guilty spark, could be the logic plague. The flood is the big bad of the universe and the thing that destroyed the forerunners so I think it's safe to say Cortana likely has the logic plague and the flood will be returning soon. Halo lore shows a lot of connections with Cortanas recent behavior and the time she spent on the flood ship.

Wasn't this what guilty spark hummed?

[@VayoMayo]

no it was cortana

[@DreadNox]

It is. The two most popular theories, which one is supported by the fact that *SPOILER* according to the books, Guilty Spark is still alive, *SPOILER END* : 1. Cortana is actually only one side of those who separated to beat the Didact at the end of Halo 4, which is the only one left and that took the advantage on Cortana's behavior 2. This motherf#cking piece of shit that Guilty Spark is is actually the mastermind behind all of this, and that is his revenge. (I do personally support theory number 2).

[@reympab29]

Well I have these theories,: 1. Maybe this new ring replaces installation 04 (the one MC destroyed) along with another AI like Guilty Spark (one with the same personality). 2. Remember in the begining there was more than seven halos (there were 12 I think) and whatever it happened to the rest, maybe there`s still one in function....... fuckin crazy theary I know (I'm not high btw). 3. Cortana turned out to be like Guilty Spark, he was obsessed protecting/firing his ring and cortana is obsessed with whatever the fuck she's up to.... lol......

[@bensambell5862]

guilty spark is in fact alive. I think he corrupted cortanas programming in her rampancy.

If she is corrupt, it wasn’t Guilty Spark. I believe that Guilty Spark was infected with some form of the flood Logic Plague, whilst Cortana definitely was. Maybe this song is a common symptom?

[@tofreedom1587]

During the level where chief arrives at Genesis, he activates multiple consoles which were activated using the "olly olly oxen free" command. Looking back at the legendary ending where Cortana activates a halo ring I can assume that the Halo ring was voice activated. 343 Guilty spark may have not had anything to do with Halo 5 or even 6. When Cortana hummed before the halo ring activaed (legendary ending) she hummed olly olly oxen free. The music which is compared with her hum is indeed olly olly oxen free. Could master chief activating those consoles have let Cortana voice activate the halo ring with olly olly oxen free?

[@NappaCarl]

Huh?

[@HoneyMochi]

Whoa, that would make sense, since the consoles font actually do anything.

[@brandoncolon3047]

Some thought that the sound heard at the end was flood screams/roars but if u notice at the same time that sound cue plays the ring lights up signalling that its been activated or at least set to standby to bad it wasnt flood related tho imagine a whole ring infected and controlled by the flood that would be a fun ring to break

The intro is probably leading to the events of Halo: Infinite, if Chief receives a copy of Cortaba. And that Installation in the ending cutscene is probably Zeta Halo.

[@E101ification]

I'm hoping it's a reference to Guilty Spark; in the novel Halo: Primordium, Guilty Spark takes over the human ship Rubicon, forcing its crew into cryo-sleep, and sets out to find the Librarian, who he believes is still alive somewhere in the galaxy. There are hints in Silentium that the Librarian ended up on a Halo ring. These events are also mentioned in the recent novel Hunters in the Dark (which also introduces Olympia Vale).

[@ZenergyLIVE]

This was the song that the UNSC used to give the 'all clear'. The fact that cortana is humming it with the halo ring in the background suggests that she has found a halo ring and is giving the all clear. 'All Clear' - Is she going to activate it? By the all clear she could mean the galaxy is all clear of all life (I think shes gonna use it as the lights on the ring lighted up meaning its powered on and maybe ready for activation. Of course I could be wrong). We can clearly see that Cortana and Master Chief have feelings towards one another throughout the Halo series and since Spartan Locke took Chief from her at the end of the Halo 5 Campaign, and because she's all phsyco now, she could be like 'if I can't have John then nobody can' and completely wipe out all life in the galaxy. This could be the plot for Halo 6 however this is entirely hypothetical. Also I think the flood will be returning, if not 343 has COMPLETELY fucked up the Halo series.

[@Bobman-ml5qf]

I have heard rumors that Cortana is being controlled by 343 Guilty Spark! And thats why she is humming 343 Guilty Spark's tune. And with the Halo rings, Cortana (or Guilty Spark) wants to activate a Halo Ring again, and wipe out all sentient life. Reason why Cortana wanted the Chief, was because she wanted a few humans she trusted to keep them alive, and wipe out the rest of the sentient life, or as Darth Sidious would say "Wipe them out, ALL OF THEM!" And it would make sense that Cortana is alive, was he Guilty Spark brought her back! Or it just could be Guilty Spark in disguise of Cortana; but I would go for where he is controlling her.
