Roswaal:  “Already, you must have come face-to-face with the issues occurring in this Sanctuary. You are likely better versed with them than I. But the problems before you are not within this Sanctuary alone.”

Subaru:  “Y-you mean the mansion…? You know about that, too…?” Subaru was horrified at the reference to the assault on the mansion coming from Roswaal’s own lips. Was even that written within the book of knowledge? Or was Roswaal simply illustrating the issue with a hypothetical?

Roswaal:  “—But of course, for it is I who contracted the assassins to attack the manor.”

Subaru:  It was crumbling. The ground beneath his feet was crumbling. Having lost the firm footing that should’ve been there, Subaru felt like he was falling into darkness. Roswaal’s confession was simply that shocking.

Subaru:  “Wait…wait. Wait a minute…you did what?”
gpt
Roswaal:  “I sent assassins to the mansion. —To hone your resolve, you see.”

Subaru:  “Resolve? What do you…mean by ‘resolve’?”
gpt
Roswaal:  “That is simple. Even with your Authority, you cannot save things precious to you that are imperiled in two places at once. You must choose what is most important to you. Once you make that choice, you can never take it back. Then, you will finally be complete. —A being who can save but one, single thing.” Subaru’s words refused to come out. It was not that he was unable to face the unpleasant evidence, or had faltered before the argument. It was simply that words did not suffice to convey the ferocity of his emotions. That was all. —Never to that degree had he experienced something that was truly unspeakable. Frederica, Petra, even Beatrice…had they died for such a preposterous scheme? For the sake of a banal plot to shape Subaru, had they been betrayed by and lost their lives to the master they trusted completely?

Subaru:  “Roswaal…you…are truly mad…”

Roswaal:  “I am indeed. I went mad long ago. —Since I was bewitched by those eyes four centuries ago, I have been mad ever since.”
human
Subaru:  “Four hundred…?” Not understanding the meaning of the words tossed out, Subaru could only repeat them like a village idiot. Once again, an issue arose from a time four centuries prior. However, it was unnatural for such words to have come from Roswaal’s lips. He, a man living in the present age, had no way to know of things four hundred years before. And yet, Roswaal had spoken as if he had experienced those events firsthand—

Roswaal:  “—Subaru Natsuki.”

Subaru:  “Ah…”

Roswaal:  “Why are you not yet mad? Why are you not yet sufficiently insane? You should be just as crazed as I…no, more.
