Not a full vampire

This new guy, Luc, He accepted my offering of blood like he hadn't fed for days. Not only that but as soon as the blood got here Emiko started to sweat. She walked quickly out of the room. Cujo followed. I ignored it. Luc finished all his blood and thanked me. I looked at him and asked if I could speak to him. He nodded and I led him out of the room.
"Your not fully vampire are you?" I asked. He couldn't hide it. He smelt too human.
"No, I'm not." He said, I don't blame him for hiding it. I would have to.
"How is that possible?" I asked, I had never, not in all my years, heard of a case like this.
"No" He said truthfully
"If you wish, I will not tell the others" I told him.
"Thankyou" He said. I gave him a little smile and walked back into the room. I decided to find Emiko and Cujo. Walking in the direction they were headed I found Emiko, in the shape of a young human girl, holding a passed out Cujo. I noticed the two puncture holes on the side of his neck and he blood on Emiko's lips.
"What did you do?" I asked her in a low voice. She looked around at me suprised.
