Lily mistook his smile as a sign that he knew she was there, that she had come to help him. "I'm here Severus," she said, brushing back the tears and stroking his hair. "Please, stay with me. Don't close your eyes. Stay awake." She wanted to be sure he wouldn't fall asleep or close his eyes. She felt scared and desperate; she knew he needed medical attention and fast, but she didn't want to leave him, even to get the nurse. Plus, if she did that, they would only hold him longer thinking himself a threat to himself. Being out of touch with him for so long, she didn't know how long this was going on, but wanted to find out first hand.
"Severus, I'm going to try and stop the bleeding," she said, her hand continuing to stroke his hair. "I don't have any potions, so I'm going to try and clear this up with a spell." She didn't know if it would hurt him, but thought it better to prepare him as best she could. Without taking her eyes off his face, she reached into her back pocket and pulled out her wand to point at the wounds. She whispered the incantation, praying it would be enough. She watched as some of the smaller wounds closed, but the biggest one, the one that posed the threat, was still open. She cursed and took the strips she had taken from her robe and started to bind his arm.
"I'm so sorry Severus," she said. "I didn't mean what I said. I was upset and angry and hurt. But I didn't want you to do this. Please, please Severus. Talk to me." Tell me it'll be ok.
