She was still completely focused on the blood when Ron began to discuss the demons. Yes that was why she was here but he wouldn't be much use if he was hurt. Especially if it was his head. She glanced out at the people walking by before pulling him back a little behind the statue, as she hoped that no one would manage to see them when they were more off guard, pointing her wand at his head when she did.
"Vulnera Sanentur," she said, careful that she pronounced it properly. Smiling when his wound healed, she kept her wand pointed at him. "Tergeo."
Once she was satisfied, as much as she could be at the moment, that he had been healed and cleaned, she reached up and gently brushed away his hair and ran her fingers over where the wound had been. It seemed good as new, which was helpful, but she would double check after they finished what they had to do. Taking a breath, she looked up at him before jumping back when she realised just what she had been doing.
"Let's get going, shall we? I don't want to risk side apparition with your head like that, even if it's healed, you'll still be slightly concussed. I'm worried if we apparate it will only make you feel sick. So we need to keep down, and keep our eyes open."
