Yeah all those souls that ended up not existing anymore along with a certain important soul that is now in oblivion, totally not relevant. No its not a "Lol u wrong" Its you ignoring that Death is going to matter no matter what. I'm sure(Unless the whole planet is wiped about the knowledge of Shadowlands) talking about where they'd end up after death is a likely conversation to have. Oh and there's plenty of dead people we didn't see in the SL but again you are free to ignore that if you want among other things.
But if we're really going for the behind the scene reasons, I'm sure SL will be mentioned..minimally(Even though I don't think SL is as bad as this forum and the world thinks it is).
