You were a human, and Spire was a soul he hasn't told you his factory because it wasn't your business, but you already knew you took him to your place, which the ghost buster place he looks around and notices the prison egg for terrible souls...

*He pushes you into the machine that turns you into a ghost....then your soul leaves your body...and you came back in...

Spire: I'm sorry....And I hope you understand but...I need to see my family again...

Your eyes turn white
