Summery: this is what I think would have happened, if Raoul had stabbed Erik, instead of listening to Christine. This is based on Andrew Lloyd Webber's new movie.
Christine watched as Raoul's sword stabbed Erik in the chest; the phantom gasped and lay limp on the snowy ground when Raoul pulled his sword out.
"No!" She screamed, pushing Raoul out of the way; she kneeled down and took Erik's hand. It was already cold and his face was growing pale; he searched her face for comfort.
"Christine, I'm col-cold." He stuttered, his lips quivering and turning blue.
"Shh, my sweet angel. It's alright." She whispered, stroking his hair out of his face.
"I'm sorry, Christine." He cried, tears streaming down his face. "It's alright, my angel." She replied, tears also streaming down her face.
"It's Erik." He said, taking a deep breath; she smiled and rubbed his hand against her cheek.
"It fits you." She replied, kissing the back of his hand; he coughed and spat up blood.
"I'm tired." He explained, his breathing growing heavy and shallow.
"No, Erik. I can't lose you, I've already lost my father, don't make me lose my angel." She sobbed, starting to cry again.
"Christine, come on. We have to go." Raoul said, putting his hand on her shoulder.
"No, he's been alone all his life, I'm not going to let him die alone." She snapped, not looking at him. He stared at her; how could she still care for the monster. He deserved to die; yet she was still calling him angel.
"Christine, if we get him back to the opera house, we might be able to save him." He suggested, kneeling down beside her. He looked into Erik's eyes; they were hazy, but he could clearly see the emotional pain and physical pain.
"I'll go get the carriage." He said, hurrying off out of the graveyard. "Stay with me, Erik," Christine said, caressing his cheek, "You are going to be fine." He closed his eyes and slowed his breathing.
"Come on, help me get him into the carriage." Raoul said, helping Christine stand Erik up; the phantom leaned on their shoulders and shuffled his feet toward the graveyard exit.
Christine got in first, then Raoul helped Erik up; Christine laid his head in her lap. He looked up at her and smiled weakly.
"Sing." He whispered, so soft, she could barely hear him.
"Sing what?" she asked, stroking his hair.
"Anything." He answered, turning his head to the side, so she could only see the concealed side of his face. She thought before starting to sing "Music of the night." Raoul looked back at them as he took urged the horses into a light gallop; he saw tears streaming down Christine's face.
"He is going to fine, Christine." He said, turning back around. She stopped singing and looked at him.
"I told you to leave him." She snapped, glaring at him.
"I didn't want to give him a chance to keep haunting us." He relied, not looking at her. Erik gasped and clenched Christine's dress.
"It's alright, Erik." She calmed, stroking his hair out of his face.
"I won't make it, Christine." He moaned, looking up at her. She removed his mask; he flinched as she gently traced the marred and deformed skin.
"Hold on just a little longer." she cried, taking his hand and rubbing it. "I deserve to die alone." He explained, his voice weak and shaky. "No, you don't, my sweet confused angel." She replied, caressing his cheek.
"I love you, my angel." He muttered, before closing his eyes.
"Erik, no! Don't leave me." She shouted, shaking him.
"Hold on, Erik. We're almost there," Raoul shouted, not looking at them, "Keep him awake, Christine." She nodded and started shaking him again.
"Come on, Erik. Wake up, please. Open your eyes." She said. Finally he opened his eyes slowly and looked up at her.
"Just another block." Raoul informed, slowing the horses down a bite; the mangers were outside when they pulled up.
"We need a doctor, now!" Raoul shouted, bring the horses to a halt. He jumped down and helped Christine get Erik on to the ground; he wrapped Erik's cloak up and propped his head up. His lips were blue and his whole body was shaking. The mangers ran over to have a look at them.
"Don't just stand there, go get the doctor." Raoul snapped at them, turning to look at them both. They looked at each other, before making their way to the opera house.
"Raoul, he won't wake up." Christine shouted. He looked down at them. The Phantom's eyes were closed and his lips were blue. She hadn't been able to stop the bleeding. He would die of blood loss, if the doctor didn't arrive soon.
