Well science was one of my favourite subjects growing up (It's too bad I wasnt very good at it) I thought it was important that even in a world of magic that science and technology is just as important. It was intentional for Kaela to split Ray and Lynx up. Although they can get along when need be, she thinks it's best not to leave it to chance. Another reason is because Lynx's magic doesn't work well with Ray's making it a better bet to partner him with Dimetrios
