I think Monty does enjoy toying with us. He has fun teasing us about things. He found an image someone made asking if anyone knows how Ruby and Yang are sisters, and all he said about it was "OH I KNOW I KNOW!" But his lips are sealed about it. He says we won't find out until it's revealed in the show.
