To say that Zelos and sleep were friends would be an understatement. Zelos and sleep were acquaintances at best, insofar that sleep was the kind of acquaintance he would probably sneak out a window to avoid at a party.

Still, there was only so much he could do in the house without getting bored, and despite appearances, he actually liked to take care not to wake up the other house residents. Mostly, it was because he didn't want to be bothered to explain why he stayed up so late.

He was used enough to working without sleep that he had very little trouble slipping through all of the traps that Ellie had set around the fortress. Of course, his motives for coming here weren't entirely altruistic, but they weren't entirely selfish either. In a weird way, it benefited both of them.

Or, it probably would have if he did anything other than act like his jackass self. He entered rather nonchalantly and sat down on the nearest thing approximating a chair he could find. Personal space? Boundaries? What are those?

"Hey beautiful, shouldn't you be in bed?" He dug himself in deeper with every word. "Women need their beauty sleep, y'know."
