I have a theory, ok so, Daedalus was a really smart inventor. And Mysterio (Quintin Beck) was a smart inventor also. Quintus (Daedalus) betrayed Percy for his own benefit. And Mysterio betrayed Peter Parker for his own benefit, finding out his secret identity, who he cares for, and other personal things. He then befriends Peter so he can later stab him in the back. Later in the movie Mysterio “dies” (that’s another theory for later) and frames Peter spilling his secret identity in the process. And if we turn to Daedalus, we can see that he befriended Percy as a spy for Luke and told Luke the camps weaknesses and that Percy Annabeth, Grover, and Tyson were coming giving Luke a vantage point. Now comparing them not only with looks but with actions and intelligence we can see that they are VERY similar. So my conclusion? Daedalus, was really Mysterio playing his mind tricks. Ok I’m off my soap box
