I want to talk about loyalty, Toby. Control recruited you, didn’t he? He found you starving in a museum in Vienna, a wanted man. He saved your life, I heard. And yet, when the time came… when it came to picking sides between him and Allenine, you didn’t hesitate. It’s understandable, perhaps, with your war experience. You survived this long, I suppose, because of your ability to change sides, to serve any master.
