Yeah, in retrospect the 3 year thing makes a lot of sense. Not sure why I didn't get that.
Okay, so let me try to get this straight. When the Song Stealer took out the CS out of Aiden's body, the body died. The CS then was just released unto Unverse, out of the Stealer's hands? Did the Stealer always intend to just let it go and disappear and not collect it? Or did it escape simply because of the Talmid Personal Soul Cellar? Either way, the CS leaves free. Grace kicks it back and it ends up finding the Future Aiden's CS fragment/dimension. It connects with that and... how does that then end up interacting with him? He gets a body, Future Aiden's body, but how does he get a body? Where is it rebuilt from? I suppose it's Creative Spark Dimension Voodoo somehow. But what we end up with is a Future Aiden body (with the body's memories) and a mostly Flumberfluff Aiden CS. And there's still a future Aiden CS roaming in the Soul Cellar and I don't know what will happen with that. Aiden's gonna be so confused going forward though. He was already struggling to separate his life from the future of Teenyweeny, future Aiden's memories and now entire body is the least he needed.
Also, how exactly did Song Stealer steall all those people? Or that is at least specifically some of them? I thought he might be getting those voices out of Aiden's memories, but I suppose not. But like there were people like the two Janitors mentioned here and I'm pretty sure those wouldn't be dead considering you'd have asked us first... or really just not done it at all. But then did you just assume the existence of more copies of them across LU and had them killed? Aside from the fact that's an extra SOS than I'd know of, that's honestly a pretty scary thought. Why are they dead and not SOS from Belladon or Wiz from Flumberfluff? Wuuuut?! Either way, though, that's a lot of killed people, damn the Song Stealer. What monster have I created?
