Thanks...I guess. [These guys are so creepy. Geniuses to be able to do all of this, but creepy. And Richie has run into his fair share of mad scientists.]
And that makes sense, for you to be able to run all of this you have to draw a line of efficiency or the entire system would crash from the margin of error.
[But the question is how the hell do you tell if someone is the same person or the person from a different universe?]
I guess my next question would be about the changes to our worlds when we're brought here. We can't leave [yet], but we'd like to know that you're not stepping on the proverbial butterfly by replacing us with someone else--even if they are us.
