Oh, yes, it was more than obvious that Banru and Morana had a past. They looked upon each other with familiar gazes, she evidently trying to muster up the courage to defy him as she never could before, and he embracing the animal side of him - the one so deeply buried. They were a wild pair - almost literally.
When Banru backhanded Morana, Tailypo hissed gleefully, slinking further down the side of the building. He never approached her closely, because if he drew near enough, he would grow so hungry that he would not be able to contain himself. Instead, he curled up like a cat preparing to pounce, his tall ears towering high above the rest of him. Under his breath, taunting words flowed like water from his mouth. Threats to be eaten, to be devoured, to be desecrated.
