Regan was angry when he saw Lavo.
He wanted Lavo to stay with Evelyn to protect her. But he was still amidst the war and he couldn't do anything.
Fortunately, due to Lavo,he was able to kill the soldiers on his way soon and reach the commander who was guiding them.
Somewhere Regan hoped that it would be Raphael.
He would be able to end everything here only.
But he was bound to be disappointed when he found out that it was someone else. He was one of the ministers in the Royal Court. Regan didn't know his name but one thing that he knew was that he was Diana's father.
Diana was a princess from a big kingdom, Astire, and her father had been the King. In other words, the man in front of him used to be the King of a big empire once.
But in front of his daughter wishes, who wanted to marry Derrick, he gave up his empire and agreed to become a mere noble in Derrick's court …just so Derrick would agree to marry Diana.
