Sebastian is a creature used to serving, even preferring it. But it's strange to given so much freedom with it. Not that he minds, of course, but still. He feels a need and a curiosity to make his introduction formally all the same.

So before the execution, Sebastian will approach the throne, and with the formality that's perfectly familiar to him after years as a servant, he drops to a knee to dip into an especially formal and deferential bow. He's not sure how much it even matters, since the etiquette may not even be the same here in Horos, but to him, it's more to show that he has no shame in bowing this deeply. Demons had a certain reputation, after all, but his own pride presented itself rather differently. ]
