Memories flashed through Quinn's mind at that moment. To prove who he was, Quinn thought that perhaps he would have to reveal his strength, show what exactly he could do and prove that he was the Hero that they all worshipped.
However, it was quite clear that even though he had performed feats that many alive today can't even fathom, they still refused to believe he was the exact figure from the previous millennia they idolised. Just then, a thought came over Quinn: Maybe he could leverage this situation to get to Logan Green?
Of course, there was also the chance that Logan wouldn't believe that he was Quinn, but there were so many incidents from the past, which if Quinn spoke about, only a few would know, including Logan, and that would let them ascertain who he was.
