vampire?

Simon's pov

Waking up the steps, I was worried what Magnus wanted. He hadn't told me what he wanted, or why he wanted me and not one of the shadowhunters. I hadn't realized I'd reached the door and knock. Magnus answered looking more worried then I'd ever seen him. "I'm so glad you came." He said and let me in.

Waking towards his bedroom, I followed. There on the bed sat a boy with Jet black hair. "Alec?" Magnus said to the boy and he looked up at me. "Thank you Magnus." He said. Magnus looked at me and said "Be nice," before leaving the room. 

"Alec?" I asked and he nodded. "Please help me. I don't know what to do about any of this, these the most." And he snapped his fangs out

"And I feel like I'm starving all the time. And the sun burns me so what happens if there is a demon attack during the day and Iz and Jace need me." He went on and on. "Alec, when was the last time you ate?" He looked up as if he was thinking. "Wait here," I told him and ran out to the kitchen. Magnus gave me strange looks as I grabbed one of the bags.

Going back to the bedroom, Alec looks up at me. Once he sees the blood, he shakes his head. "No way am I drinking that." "you already have. It completes the transformation." I see Alec's  eyes widen. "I-I don't r-remember drinking it." I nod.

Cutting the smallest of holes in the bag, I let a little drip onto my hand. The smell was so amazing. It took everything I had not to drink the bag dry myself. I have to help Alec I kept telling myself. Looking up I could see that Alec was doing everything he could not to jump off the bed and drink. "Here," I handed him the bag and his fangs snapped out. "thank you," was all he said before he drank the bag of blood dry.
