Just tell me

Ren looked at the smiling Harold with a frown on his face. This man claims to be his descendant but since there's no way to verify this statement Ren decided not to believe it. Though Harold's story was somehow believable since most of what he said was something that really happened. Harold even knew about the half-human grandchild that Ren knew nothing about. Still, what happened in his past life, was not something he should worry about. 

"What are you talking about? Who are you calling your ancestor? You're older than me and you claim that I'm your ancestor, that must be the most idiotic joke I have ever heard." Ren acted like he had no idea what Harold was talking about.
