(Gonna skip Barbra cause she'll be Lilly's fiend since she was 12. Go with it)
Lilly's POV
I cleaned my bike as father cam in the cave with another boy but this I knew who he was. "Talia," I asked. "Yes," he answered. I nodded walked off to my room not wanting to interact with the demon. Bruce told us all everything in the morning. "Hi Damian," I said bending to his level and help my hand out for his to shake. He looked at me walked away. "Wells he's delightful," Jason said and out of nowhere there was knife headed for him. I grabbed the knife before To could do some damage except for cutting me. "Lilly are you ok," Jason asked. "I'm fine jay-bird," I said. "So I need to make cupcakes in honour of a new member of the family. Dick don't eat the frosting or my sai will be up your ass, got it," I asked. They nodded and left the room. I got everything out and begins mixing the batter, I put the batter in the cupcake tray and put in the oven and began to make the frosting. Half way through Damian came in a saw was I doing. I smiled at him and went back to work not wanting to brother him. "What are you doing," he asked. "Making cupcakes. What your favourite colour," I asked. "Green why," he asked. "I just wanted the cupcakes to be your favourite colour and something you hate, I care about everything and everyone here Damian. I don't let anyone hurt my family," I said. He ran to me hugging me with tears. "What's wrong," I asked bending to his kevel and wiping his tears. He cried harder and I picked him up. He was pretty light. I took him to the living room where he fainted. The boys looked at him as I pressed his chest and I felt something weird and I took of his shirt and I gasped. You could see the outline if his ribs. I pulled his shirt down and went back to the kitchen. The cupcakes were ready. I asked Alfred to put the frosting on as I made something more filling for Damian. I made some fried rice, soup, and breadsticks. I made some for everyone so it was equal. As dinner time rolled around I was tried but I brought everyone to the table.  Damian looked at me. I smiled and he sat down Beside me. After dinner I lead him to his room even if protested. "You know even Jason wasn't this difficult," I said. He pouted and I kissed his nose. "Damian what happened why are you so thin," I asked. "When I was in the league of assassins, I never got to that much since I need to learn I how withstand pain," he said. I ran my fingers through his hair. He passed out soon after. I know one thing he's not going back to them.
