The “subtle implications” I was referring to, were not based on the threee main characters perspective. Gryffindor is made to seem like the best house. It’s always mentioned first. Many awesome wizards/witches were in it. Their crest is a lion.
Speaking of “hero material”, I would be more likely to describe it as hotheaded impetuousness. Especially Harry. There were many occasions where he played the hero. Did he have a plan in any of them? No. If not for the fact that he somehow always gets lucky, he and his friends would have been dead many times over. The need to be a hero is not a good trait, I think.
