It was proven by Saitama himself that he has amnesia, The Blast could only be a lie to be the Saitama, remember when Saitama did not notice that he was not recognized? So he must have forgotten for the reason that he was already registered as a hero, Only that no one knew him face to face, other than Tatsumaki, and that's where the question comes in.
