Like to young teens who only care for his point of view, not caring or wanting to understand other people point of view. Heart kinda tired of try to deal in good terms with him. If Nathan will not try to be in good terms, so Heart will prompt ignore him like a statue, since Nathan give the same threat when Heart try to talk with him in the Little Cup. If Nathan have problem with that, he will have to deal with it, liking or not. Heart will NOT begin a war against Nathan since this effect the group as whole, but accept Nathan as friend/parthneer in the group, not anymore. This time Nathan will have be the one to act.
