There are a couple questions Aymeric asks and one may sound strange, perhaps a hint of something weird on in Heaven: what kinds of experiments does he do and who is Abe no Seimei. If asked if he's serious or anything like it, he will confirm. How can he know about the truth if the idea or the person is dead?

Besides, he would also add if Ryou knew magic, he would have been able to defend against them and to evade capture. So it's kind of a reverse question. But he will also keep an eye out for the shinki searching for him after he hears of the mention of someone dying due to Heaven knowing of magic within humans. Something's off because of the creed of Heaven mentions not to harm humans and yet here is this claim. Aymeric will then ask what proof he and the cult has in order to verify this. That he wants nothing but the truth.
