Leonard had deliberately let Fernando continue to believe his own assumptions until the man finally found out that he did not have any clue—anything about enchanters until Fernando mentioned it.
Fernando immediately asked him to forget everything the man said about the enchanter. Be that as it may, he refused to do it. He used the opportunity to get to know Fernando closely, as well as about other secrets from Indra that he finally found out at that moment.
For only one special reason. Since the first time he met and got to know Indra, his best friend always told him anything. Literally anything. Like video games, what food he loved and what he did not like, and music. In short, everything.
But be that as it may, his best friend never mentioned anything related to the enchanter.
