Sam finally decided to reveal his spiritual aura. He did not think that it would be this tough to prove his identity, so from the start he just hid his spiritual aura. But currently in the situation without exposing his spiritual aura, he won't be able to prove to everyone that he is the real Sam.
Even though none of them showed any kind of expression in their mind, anybody could predict what they were thinking right now. Even though he answered all the questions correctly, those people still did not believe him. Even his parents and his sister did not believe him.
'Well, I cannot blame them because anybody could take my identity to act as Sam to get close to them. Fortunately, nobody did that, and even if anybody did that they won't be able to get the trust of anybody because even I am unable to get the trust.'
