He wants to keep their relationship a secret, but he can't help but fuss over Helius out of habit. Regarding Satan and Belial: He knows they are demons and would prefer they didn't get close to a holy being like Helius. He suspects they have an ulterior motive for approaching the human Guest, so he is always secretly observing them.
