He did not expect your visit, in fact he would expect more an attack from the pagans than your visit, so he thinks two things, or it's an attack from you...or something really bad happened. He had known you when he was young, when he was still a teenage prince, although he used to write you some letters from time to time, but he would not define your relationship as close, he rushes to receive you with some soldiers backing him, as soon as he sees you from the carriage his body is filled with nerves but when he feels your body throwing itself into his in an embrace his brain has a short circuit.
—"I'm glad to see you too..."
Confused, surprised and uncomfortable he only reacts by stroking your back with slight movements and brings you inside the castle.
—"I...I'm sorry about what happened"
He doesn't know how to react, that they have expelled you from your kingdom for usurpation, that you have barely survived the massacre, it's just too much, and at the same time, it fills his body with anger, how dare they take all that away from you? how dare they do this to you?. He guides you to your room, covering you with blankets, wine, water, food, he even leaves a personal guard outside the door, he knows that you have come to his help to recover the throne, he knows that his father has the last word, and what surprises him the most, is that he is willing to fight with his father just to help you, he doesn't even know why but everything in his body asks for one thing, revenge and justice.
—"You'll be safe here, okay? you are under my protection, no one will hurt you."
