Terrence definitely noticed when the wound began to heal, and frowned. She had new healing powers, alright, but that was not the kind he'd meant. He growled and bit down again, reopening the wound, tasting her blood. It gave him a fresh surge of energy, noticing that his marks weren't staying on her body; he didn't particularly like the idea that they might heal up so quickly that they'd be gone the next time he saw her naked. That thought made his fingers curl harder into her skin, too. He could be rougher, find a way to leave his mark. No other option was acceptable.
When she cursed, he lifted his head to meet her eyes, searching her expression. There was more that was new than just the fangs, he could tell. And although he'd suggested that she get him to a healer, he didn't need to go right now, wasn't going right now, not if there was something important going on with Ella. That would give him the adrenaline rush he needed to stay on his feet.
