The god of power sighed and said, "I know I shouldn't be here. But I..."
The Overgod interrupted him, "But what? Tell me, why are you here? What got into your mind to come to the void universe? Are you out of your mind? Have you lost your memories and forgotten the terror of the Supreme? Or have you become bored of life and want to die?"
The Overgod hit him with a lot of questions. It is clear that the two of them know each other. The god of power knows how the overgod came to be, and he knows the duty of the overgod.
The Overgod, on the other hand, knows his true identity and his relationship to the Supreme. But that didn't mean that it would go easy on him. It can't do that even if it wanted to. It is just like it said; it has to do its job.
The Overgod didn't wait for him to answer the questions. It said, "You have brought this upon yourself. I will beat you up and end this farce before it becomes too late for you."
