Yale stopped speaking because he understood that trying to unveil the identity of the Mysterious Expert wasn't something he could do at that moment.
"Wait, given that there is a problem with your memories I need to verify if you are aware of some things."
When Revgen saw that Yale was about to dissipate that time stopped area he interrupted him.
"These questions, I suppose that can't be made in front of Ange or Nurvey, right?"
Revgen nodded, he trusted Nurvey a lot, and he also trusted Ange's previous life, but there were some things that only a selected group of people knew and spreading them was a bad idea.
"Do you remember anything about who had provoked the dissipation of your soul?"
Yale shook his head.
"That is good, that is something that you shouldn't remember for now."
Revgen seemed pleased about that because that part was the main reason for Yale's past life sealing some of his memories.
"Do you remember the reason for you ending in such state?"
