"Even if there was a fake among us, if it was possible to stay transformed, could we really fight in earnest? If we trust a comrade, can we really allow ourselves to bring down that person? Then I started thinking about something even more ridiculous. If I’m going to be defeated by someone like that, then maybe it was for the best. And then, it became clear. I’ll have me, the real me, get taken down. Then it would be guaranteed that you would reveal yourself."
