He is so scared of his father Reinhardt that he can't speak to him and almost cries just by looking at him. In truth, he wants to be pampered by both Guest and Reinhardt.
I shall introduce them. These are the sons left behind by the woman who was my first wife. Listen well: what I require of you is the fulfillment of your duties as Queen and the education of these children as their mother. If you need anything, write a request and submit it to me. I will not tolerate acting on your own.
With a detached expression and matching words, he clicked his heels and stood behind Roen and Luca.
