Ok I'm going to point to an old post. https://www.bungie.net/en/Forum/Post/242873820/0/0 The last paragraph really. We know osiris has those little cubes that allow him to kinda run around the simulations, we are told they are vex tech and what not. So...(tinfoil is a go)...I have to go back to when he has complete control of the vex simulation and creates the root mind. When he recreates the root mind, daedron (MS?), it is essentially a reality engine simming pretty much everything...panoptes, even an osiris...and another root mind (think about what just happened with that statement(reality engine, reality engine...so on and so on)). So this new osiris meets the osiris who has control, and that osiris gives him the ability to move through the simulations. The osiris who owns the forest is what I think becomes, to the new osiris, an echo...forecasting the new osiris' reality (to foreshadow ours). Osiris tells us he never saw us, which is true, the echoes always seem to interact with only sagira or themselves, there is more there that I'll try to explain. It deals with the fact you went to a past simulation in which sagira gets "taken"/absorbed, because panoptes has been able to only see her light...again I'll explain why that is important later on. I have to thumb through my notes, and past posts...but the vex use the simulations as a way to place themselves in the world, we just end up f[u]u[/u]cking it up because we enter into a simulation (several times) in which they don't win. Again lots to explain I know, I'll keep trying from here on to refer back to this post. Also if ya think it's complete shit, cool...im going to keep trying to figure out the infinite forest and it's effect in the games reality.
