"Your friend Lewis is the one responsible for this," Melissa's doppelganger explained.
Did Melissa know someone by that name? It did sound a little familiar for some reason.
"He found a way to bring people to this universe using an inter-dimensional portal. I'm you, from another parallel reality."
"That's unreal. You mean all that quantum reality stuff isn't just science fiction?"
"Well, yeah." The other Melissa paused, then looked concerned towards Melissa. "You really don't remember any of this, do you? Maybe me being in such close proximity to you is affecting your mind. We should go back to Lewis' place to figure this out. After all, if something's wrong with you, there might eventually be something wrong with me too." She grabbed hold of Melissa's hand and pulled her with her. "Come on."
Still dazed by all the new information, Melissa helplessly went with her. None of this made any sense. Her doppelganger wasn't from another reality. She witnessed her boyfriend Jeff turning into her right in front of her eyes. And what happened to him anyway? Her doppelganger didn't even recall being Jeff. Was he gone forever?
