Lily fell to the floor, but her own pain wasn't anything compared to his. She hurried over to his side, looking over at the cut on his arm. Warm blood was seeping through the rags she had wrapped around and she felt nauseous. All that work for nothing and they were back where they had started.
"Oh Severus, I don't know how to move you!" she said, feeling close to crying. He needed attention and fast, but how to get him there? She looked down at her wand, thinking over the various things she could do to help him. There was always levitation...but that took a lot of concentration and she wasn't sure if she could do it with her thoughts of Severus.
As he continued muttering she knew she had to make a decision and fast. She pointed her wand at him and muttered the spell. "Wingardium Leviosa". Severus rose a few inches in the air and Lily carefully began to steer him towards the door. She didn't want to drop him.
She was able to make it to Slughorn's personal door, knocking hurriedly and loudly. "We're here Severus," she whispered, looking down at her friend. "Profressor! Are you there? We need you're help!"
