Regressed In Time

I laughed at Lucas, pretending to be unaware of the situation, and stated, "You are too young to have a lover, Lucas." He just indirectly confessed that he came back from the past. Was he unaware he was just making himself look like a fool in front of others? It's good for him that I also knew about the past. But I didn't see him in that past, though. I think the former Avyana had a short-term memory.

"I was not talking about my current self. I didn't even think that I met you in that town. You were the enemy that I loathed, but at the same time, the girl that I was badly trying to find." He really mentioned his regression from the future. How come he remembered everything? He should be careful with his words to others.
