Totally and completely missed that. Good to know.I also really have to wonder about the naming conventions in this place. I had assumed there would always be 26 actives at any given time, but the way they refer to Alpha would seem to imply that he hasn't been replaced. Additionally, you'd think Saunders would wonder why there wasn't a Whiskey wandering around (since she's still technically a doll, I can't imagine they would've replaced her...an idea reinforced by their seeming lack of confusion when Topher was talking about Whiskey's imprint).
Topher mentioned that Dr. Saunders was "Whiskey 1.1," so perhaps she was replaced by Whiskey 2.1, and likewise with the other Dolls when they are replaced.
