Stephen figured it out first, I don't know exactly how. But then we all found out anyway when Requiem came in from outside our world with a big spider demon that eats souls and makes new realities out of them. A bunch of people followed her trying to stop her and we found out she used Infinity Stones to fold the universe in half. They were going to split us all in half but Stephen wouldn't let them so they duplicated everything first. Then later he showed me with the Eye of Agamodin. I can only figure out who people are from the similarities so I don't know who the other one is, I think it must be someone the people from Wanda's world don't know. But it's not like being two people. I have my own memories so I'm not going to do the same things as them.
