People couldn't even know Em was alive unless they could be trusted...or in certain cases found out and met up with her anyway, even though Kingsley didn't trust Severus Snape one bit. The man had almost caused her death, had certainly caused others, and to Kingsley's knowledge, it hadn't really been proven worth it. The man was involved in many horrid things over the last few years and really hadn't shown any proof that he wasn't just sitting comfy on the other side.
"That's the Em I know and love," Kingsley turned to take her hand, his thumb rubbing against the skin. "You're an incredible woman, Emmeline. Never forget it."
