So many people know that Halo Reach was the prequel of Halo CE. But if you think about it, Noble six is actually stuck in an infinite time loop. What I mean by this, is that Noble six is repeatedly doing the same thing over and over again. Now you must be thinking that I’m high or something, but hear me out.
Section one
Notice how on Reach, in the intro, there is a damaged Noble six helmet. This is showing the end of Halo Reach, but as for Noble six, it’s not. It then moves on to a warthog with Noble six in it. Here he is beginning what he had already done.
Section two
Notice how in the last mission, Lone Wolf, the banner on the bottom says, “there will be another time” Or something like that. Then, when Noble six meets Noble team for the first time, in the falcon, Carter says, “… That Lone Wolf stuff, Stays behind. Got it?” Now how on Earth does Carter know this? Well, Kat read his files he must of known somehow. Besides Noble six probably survived the torch of the covies and maybe thats why ONI put him on a team so he wouldn’t get his -Yoink- beat again. After all, the game never showed Noble six’s dead body.
Another piece of evidence is that Halsey, narrating the final cut-scene, says that they could rebuild. This doesn’t actually mean rebuilding Reach, but it could mean that.
You: “WTF are you talking about?”
I know it’s pretty hard to understand some of this stuff, but before reacting like a b**ch, take a while to think about it. How Noble six could be stuck in a time loop.
