Are you the only Katie Hunt now?

The puzzled look on your Katie face in the mirror certainly makes you look cute. Your new-to-you Katie memories include your finding the pair of pen-shaped costume gadgets, zapping Jessica with the black one, putting on the Jess suit and turning into the fake Jess, zapping your Jess body with the brown one and feeling her memories and persona flood in... It's all there, right up to seeing David-as-Trish (you, at the time) zap you with the black one.

There's no trace of a memory that can explain how as David you could have met Katie on the way to Jessica's room, while the Katie you've become for now was already wearing Jessica. If there's another Katie out there right now, no memory currently in your cute Katie head can help you explain how or why.

You admire your naked Katie body in the mirror. Your Katie self and memories make it seem perfect for you.
