M-21 hated waiting. Especially for something he knew was coming. What was the point in wasting time, unless it was to watch him squirm?
It had been a few days since Frankenstein and his master had taken them into their house and they hadn’t started yet. Maybe they wanted him to settle in first, but he knew where everything was and wouldn’t get lost.
If they weren’t going to initiate it, he would.
Better to get it over with as soon as possible.
