Actually they can but its rare and there's a legend behind it as well. Something about people going to watch a shooting star or something going across the night sky and came back with pale skin and violet eyes. It might not be true since most people that have them have albinism. There was also a debate on whether a person called Elizabeth Taylor had voliet eyes or not
You do reliaze they aren't the first son x mother ship but I guess the one I am thinking of wasn't really intended to be a son and mother thing since somethings you see in an anime inazuma eleven go chrono stone (no it's like a second season of a go series) anyways. There were a ship between two characters nanobana kinako and fei rune (spoilers for episode 46 and 47) by near the end of the series it was revealed fei father had gone into the past to get his future wife as a child to go further into the past to help their son fei. So it depends on when you ship them and if you continue to ship them. Honestly my opinion is it's gross to ship even siblings together let alone parents and their children.
Shiro had died eailer in the show so when they found out shiro spirit was in the aseril I might have spell it wrong but it's basically the lions mind. Allura use her magic to place his spirit into a clone body and now he is alive
Am I rude then because I didn't cry at the end since allura dead was hinted at since season 1 but apparently the way season was suppose to go was that all the paladins die. So i am not happy it ended the way we got doe.
