When I woke up in the morning, I saw an unfamiliar ceiling. Looking around, I saw a room I didn't know and a view I didn't recognize. ...And in the window, a face I didn't know. I had been swapped.

"This is bad..." Just as I was slumping my shoulders, the door opened without a knock. "...How unusual. To see you actually awake in the morning. ...Here is your breakfast."
