Seth POV
"Jake!" I shouted.
He came running out quickly. He bent down next to Leah and turned her over onto her back. I had her head resting on my lap while Jake checked for a pulse.
"What happened?" he asked, urgently.
"I don't know" I replied.
"I'll get Carlisle" he said and he began running back.
I stroked Leah's forehead with the back of my finger. Jake was back in seconds with Carlisle. The vampire Doctor bent down and checked for Leah's pulse just as Jake had done.
"What's wrong with her?" I asked.
"She's unconscious" he said. "Tell me what happened, Seth"
"Well, she was all mad at me and yelling at me, and then she started groaning and holding her stomach, and then she just like collapsed" I said, quickly.
"All right" Carlisle said.
He picked Leah up in a bridal style and carried her back to his house with Jake and me following. He went right past Bella, Edward and Rosalie. As soon as Esme saw that Leah was unconscious she darted after Carlisle. We followed them to a room that looked like a cross between a library and a hospital room, Carlisle put Leah down on a metal table. I was at her side in seconds, holding her hand. Carlisle pulled out a syringe and was about to put it in Leah's arm when Jake stopped him.
"Woah, woah, what are you doing?" Jake said, putting his hand on Carlisle's arm, stopping the Doctor.
"I need to take a blood test" he replied calmly.
Jake nodded and stepped back next to me, my hand was still stroking Leah's motionless face. I winced as Carlisle stuck the syringe in Leah's arm and filled the barrel with her blood. Leah's face flinched then relaxed. I also saw Esme cover her nose when Carlisle took the syringe out of Leah's arm and a few drops of her blood spilled out. He put a little bit of cotton wool on her wound and held it there for a few seconds.
"What's wrong with her?"Esme asked in her motherly tone.
"I don't know" Carlisle said, filling a little test tube with Leah's blood sample "I'll know in the morning"
It was already eleven at night so I figured that I would stay with Leah until morning. Jake went on patrol at around two while I stayed with Leah who still hadn't woken up. When morning finally came, at eight to be precise, while Leah was still unconscious, Carlisle came upstairs with a weird look on his face. A mixture between shock, and a little bit of happiness.
