Louis, he's not confident and thinks he's not worthy of Maetel. forgiven. moreover what makes him not remember everything is the drug from Rafael. The last time the person he remembered seeing was Rafael. There was no reason for his to know clearly that it was Maetel's child because his sex was completely drug-induced.It would be very strange if he found out that it was Maetel's son even though his memory was never related to Maetel the last time
So far only Prince Maetel has purple eyes, it seems to be so rare in this country.
Louis should have noticed the baby dragon has purple eyes & realized who’s daddy.
