Ba'al does wash his hands before moving over to the sofa. He's not OCD but he does like things clean and neat. Of course there is some deep seeded symbolism in from centuries of being treated as a god.

When he sees him kneel he gives him this odd sort of look of approval. He takes his seat with the plate in hand. He considers the food then picks a piece. "Open," he says before holding the piece out to him.
