Well as long as he stayed beside him, he was sure that Ryzel's safety would be guaranteed. Unfortunately, he knew that he couldn't always stay by his side.
He would also lead the army and fight the Zergs so he couldn't always be by Ryzel's side. Some of the people with bad thoughts might take advantage of those times so it was important to set up a security team for Ryzel.
He already arranged guards for Ryzel in the past but now his security would be doubled. In the past Ryzel wasn't in too much danger as the only ones that was dangerous for him at that time was his relatives and some accidents. But now he would be in more danger, so he needed to have more capable guards around him.
Layton Lewis doesn't want Ryzel to have any accidents, so he was preparing his security. He didn't dare to imagine a life without Ryzel as he already has him in his life. He would do his best to protect him as long as he can.
