Funny you should say that. I just did that very mission earlier today. Anyway this quote is said two missions later: "Kirchmer was the second student I've had killed. The first was a PPD officer, a man named Stewart Tones. I knew him very well, he was one of my most intelligent students. I did not want to kill him, Character, but it was either him, or me. I pleaded with the boy to walk away, but he insisted he was 'serving the good of Praetoria'. After all I taught him, he still had that naive, ignorant view. I shot him in the head before he could shoot me. I truly believe that on that day, whoever I once was died."
