It was said in her best Jackie tone which wasn't entirely threatening enough as she wasn't exactly a mum and she certainly wasn't the mum of a man several hundred years older than her. But it would have to do. "First of all, he's not a threat. He wants to help. Like Jack does. Secondly, you shouldn't be worried. He's not spreading it, Jack saved his life.

That 'why did you wander off when there are deadly things around' look, or the 'you don't have to talk to all the strangers because one of them could kill you, you know' look. But it was her turn. He'd taken care of her plenty. It was her turn. "I promise, if there's anything that comes up, there's plenty of us who can take care of it. You have to heal." She rested a hand on his chest, as if forcing him to stay put, but it was, admittedly, partially to feel two hearts working together, even if weakly. So long as they were beating, she didn't care. She knew what happened when one stopped. She'd seen it first hand. She didn't want to see it ever again.
