You were with us. How could you have been here, too? Unless it was some kind of trans-dimensional timewarp. The you who was with us was the you from after this. Although if that were the case, you should have remembered this whole experience. Maybe there's some kind of mindwipe protocol once you leave.
But still, I'm from your future, how awesome is that? If we can figure out someway around the protocols, maybe we could change the world. If I help you win the lottery would you buy me a new baby for my lab?
