I think it depends from the world. You know how we all come from different places? Not long before coming here I met Hades in another world. Not a nice guy. I bet if he wanted he could make ghosts do whatever he wanted.

[And given the whole mess with the worlds that's going on here, it's not impossible for that Hades to be doing this]

I take no responsibility for anything that's happening here if he's the guy who's telling us to kill each other!
