"I can never understand what is the problem with you all. It's the same with the old man. You all treat me like a kid who doesn't know what I want? Do you really think that I would need your advice for anything?"
Azekiel was already very frustrated, and his frustration only increased the more he heard about it. He knew that at this point, there could soon come the point where he must actually kill whoever mentioned this thing in his anger.
He still needed the help of his Mirror Reflection, so he had to play along. Only his mirror reflection could properly awaken the inverse key.
The mirror reflection could see the frustration of Azekiel. He didn't want to make him more upset, so he just became silent.
He didn't talk about the past. Instead, he only talked about the future.
After a long journey, he finally reached the eleventh floor with Azekiel.
