At another point in his life, he might have met the roar of his name with great pride, or the charging of the dark body with his teeth in a playful game of rough-housing. If he'd been human Revui would have probably side-stepped with one foot out, just to watch his brother trip and tumble, then laugh about it later over some cheap beer.
