The pianist should definitely indicate whether the block on Mental has passed or not. Because, if it has, then with a high probability, he can be executed the next day. And Hugh should take a risk, in my opinion.
2) The researcher said that I am a human. If you think that the note from him is a fake, then why didn't the real researcher respond? After all, we know for sure that he is alive.
3) What does "Hugh will take a risk" mean? To kill me? I don't even doubt that he can do it.
And in general, when I read your arguments, my hand reaches for my forehead and makes a loud sound as it hits it. Do you just want to execute me? Then just say it, I won't be offended, just don't talk nonsense.
