Erin was on patrol when she heard the noise, a shimmering tingle in the air just to her left that made her nerves go on end. She took a few steps back, ready to spring, wondering what was about to jump out at her. This was supposed to be a nice, quiet August patrol to stretch her muscles, here in the relatively good neighborhood abutting Lincoln and Bayview! The noise became a shape, then a glow, a rectangle shaped like a door. And a figure walked out, a very familiar one.
Erin White looked at her double, her blue and white uniform oddly familiar and yet oddly alien. It was a morphic molecule costume like Wander's, but the symbol on the chest was a big letter A and an atomic map of uranium: the symbol of the Atom family. "Hello, Erin," said her doppleganger, a look of familiar determination in her eyes. "I know this must be very surprising for you, so I'll try and take it fast. Are you familiar with parallel universes?"
