The moon was everything keeping him in this form that Ba'al now had at bay on a locked away from society compound of cult followers. He thought for a moment as he stood in human form before him to keep the boy as a pet, chained, and unleash him within the confines of the grounds just to cause his flock, his sheep, his brainwashed followers needing his own assistance further. Give them even more reason to believe he was their God. What a set up that would be! But, then Ba'al realized he'd have to feed the thing in meantime and wasn't in the mood to deal with a full-time capture.
He stood emotionless and cold as he was watched the hound snap at the silver chain and reacting like he'd bitten knives. He finally lowered himself, knees bending, still pupil-less metallic eyes connecting with the wolf's, his own head canting like a curious dog. "Bad doggie. Tsk Tsk." The edges of his voice still held the edge of buzzing insects and a slight lisp. He sat down just out of the canine's reach and laid down, looking bored. No matter how much Casper snapped or attacked or whined or cowered or anything that the werewolf could choose to do was ignored and the demon not even flinch. He just laid there, like he was waiting something out and nothing of relevance. Bored out of his skull no matter how entertaining another demon might have found Casper in that moment.
Then it came he rolled back up and yawned. The sun would be rising soon enough. He wanted to make sure Casper actually remembered this experience. What good would it do if he couldn't remember by morning?
He would wait for the naked human form to appear in that shackled collar and approach him as his body was still in mid-change and hard to have reaction and yank the collar tighter to fit his thinner neck.
He stood back just as Casper completed everything wholly would snag him by a fist wad full of that blond hair and say, "Hey boy. Wolf boy." Then he'd whistle like he was calling a dog in sarcasm, "Here's how this is going to work" practically spitting in his face, "You're going to come back to this spot for the next three moon. Got it? If you don't show up what you feel with THIS-" and right then he jabbed a silver pendent of a star he had been wearing around his neck, long point tip first right into his gut, ripping through his flesh and held his hand over it waiting for the heeling to smooth it over like it had never happened. Ba'al knew it would eventually fester and had to be burning already. He would try to remember to tell Astarte this one. "-will be like nothing compared to what will come to not just you but all you hold dear. A little sphinx? What's his name? Did I hear Taj? You will come here for the next three moons or Taj will be my next target. Do you understand? Do you agree? Do we understand I'm the master, you're just the pet. Are you going to be a good doggie for me? You'll even get treats when you come." His hand started to release the blonde hair, but he did not move from Casper's personal space.
