This wasn't Bones. Kirk knew it instantly, the very second it happened. That calm, level tone scared the fuck out of him. This was Doctor McCoy, the thing George was talking about. It was like suddenly learning his best friend and lover had another person in him. "Don't." Kirk snapped, venom in his tone, "Don't you dare do that to me."

His fingers tightened. He could remember a woman staring at him, using that same voice, trying to ask him questions he couldn't hear.
