I suspect that s mail has been really guarded in this because he's just using the possibility of of sci fi worlds as sort of metaphorically, like to talk about time. I know that people probably want to believe that they white rose really is building something like a parallel universe machine. But if s mail shows us some sort of actual sci fi device, I'm not sure I wouldn't feel a little betrayed. The rules of this world haven't hinted at anything that sophisticated. So you want it to not be a science fiction outcome? I think that with three seasons of never even throwing us a bone about about any actual sci fi stuff that I think it would be a little unfair now.
