And Damien is gonna be the next ruler of hell in a few years so his father Satan wants him to train up. But there's a thing he has for Pip, he is secretly in love with him. But he doesn't think that his father would ever approve of that relationship. So he just stayed silent about it and tried keeping distant from Pip...
