[@Im a huge mess]
You know it just hit me, Cody never declared himself as THE hero just as A hero XD
So just because he is a hero, doesn't mean he is the hero destined to defeat the demon king so this argument was started over her just assuming he meant THE hero XD
Plus even if someone tells him he can't be that hero, doesn't mean it will stop him. In fact he should become Noel's friend then find out he is the demon king XD
He will probably go into denial
