Oliver looked like a real angel without a metaphor. He couldn't have done anything more than he did. He looked like an angel. The angels that are around their heads are an aura of those Norse aura. Oliver looked like them. Not just because he did something heroic like save them at the last minute before being devoured. But it's also something else. That thing was that his picture was at the top of the hole. His picture came from behind the moon.
The moon was making a great light aura around his head.
He's really an angel. Leo and Emily were stuck down there stuck so it couldn't be solved. They were too heavy to be carried together by Oliver. It's like they don't have time to go up one by one. They can't do that. It looks like Leo's huge fall made enough loud to hold these monsters back. If the Mother Beast was still unconscious, she could not be the one seeking them now. Leo was about to commit some kind of crap.
