Lilly's POV
Only Natasha was still up when I started heading off to my bedroom, I walked past Bucky's room and heard the tortured grunts and moans from inside his room, I pushed open his door and stepped inside, the room was mostly in shadow apart from a small strip of light being cast from the city light from outside. I walked over to the bed and knelt down beside the bed and pouched his hair out of his face gently with my long fingers, I started gentle drawing circles on his hand, his skin warm to the touch, I wanted more than anything for his hand to wrap around mine again, to make me feel safe. I closed my eyes and started to hum the soft tune of an old rhyme I knew. Then singing the words softly, Bucky turned over in the bed so he was facing me, i checked his face and saw much to my relief his eyes were still closed. I just watched him and sang hoping that in some way I was helping him through his pain and torment, just as he had done for me on the night of my twelve birthday, the day I had gone through my torture training. He had come into my room and simple sat beside my bed holding my hand in his and whispering that everything would be ok. That pain didn't last forever and even if it did he would be there to protect me. Bucky seemed calmer now and It took all of my effort to drag myself away from him and not stay by his side, I closed my eyes giving him once last glance before turning and heading out of the door without looking back.
Bucky's POV
I felt something tickling my hand and a sweet sound but it was so pleasant I didn't want to open my eyes, I realised that it was obviously a hand resting on my own and the sound of someone singing quietly, I desperately wanted to open my eyes and see who it was but I didn't dare worried that the person would stop. All tension in my body relaxed at the touch, and only moments after I had settled into the touch did the hand leave mine, my hand twitched begging for the contact once more but I was disappointed. Hearing footsteps I opened my eyes slightly and saw the retreating figure of Lilly leaving my room.
Lilly's POV
I dragged myself back to my room reluctantly, begging my emotions to stay calm and collected but I was losing my battle to them, I was sure that soon they would be what was dictating my emotions not my mind. My whole body began to shake and I steadied myself against the wall trying to quell the action to no avail. My chest was tightening dramatically, i knew not to panic that was the worst thing I could do so I did the best thing I could do call for help. I clumsily crawled over to the side table beside the bed and hit Jarvis's emergency button, seconds later an alarm sounded and Jarvis's voice called over the system that there was an emergency in my room, I looked to my hands again and was confused to find them changing to a blue colour. I took a calming breath as best as I could with my tight chest deciding that I would wait for Dr Banner's diagnosis. Tony, Steve, Clint, Natasha, Bucky and Thor all darted into the room, Tony was the first to spot me on the floor and rushed over "what happened" I lifted up my hands for him to see, somethings happening, "is it the serum?" i asked hearing the terror in my voice that I could not hide. "Can you walk?" he asked surprisingly gently for Tony, i shook my head "Im sorry, i can't i'm not strong enough right now" he nodded and beaconed for Steve to come over and lift me up which he did with great care, then we all rushed down to the lab. Dr. Banner looked surprised as we all burst through, "Got anywhere with that serum?" asked Tony walking over and looking over Doctor Banners shoulder at the screen he was working behind. Steve placed me down on the metal bed though supported me in an up right position. "Actually I have" he answered getting up and walking to me, "never mind that, what about her hands" clint gestured towards me. "Well this actually backs up my theory" "the suspense is killing me" Natasha drawled but did look quite interested in his scientific diagnosis. Dr. banner walked over to me and stood before me "I think it would be better that I spoke with Lilly alone" "why" asked stark still trying to work out the readings on the screen. "Doctor patient confidentiality" he smirked at stark who wandered out of the room followed by every one else, but I wasn't sure I wanted to hear this on my own "Shiny" I called quietly "Steve, can you two stay please" the both looked some wheat startled by my request but nodded and returned to my side.
Only once everyone else had left did doctor Banner start talking "Well Lilly when you asked about the Serum, Im assuming that you had no idea what it was, not only what did" i nodded "well then first off I will explain what it is, the serum is a highly volatile one much more aggressive than Steve's and mr Barnes and it was actually designed to effect the subject in a different way. You see the Serum was supposed to to effect the electrons to the brain to stimulate every area of the brain, causing greater intelligence, increase the build up of muscle strength, faster healing,slower ageing. Which it was some what successful in doing, the reason you survived is your genetics, but i will explain that in a moment. You see the reason all others died is that the Serum can't be successful when used in humans as their bodies are to weak to handle the serum." I looked at the doctor "but wait i survived,, but you said…" he stood there for a moment his eyes on me with sympathy until i realised "You said human am i not….?" I trailed off. He shook his head smiling "don't worry your not an alien or thor like in any manner, essentially you are part human part something else" "something else?" Steve questioned "have you heard of the mutants?" he asked. Oh shit no, i looked down at my hands things clicking into place, I shook my head taking a deep breath "so most likely my mother was a mutant?" i asked feeling ill. "Well the scans on the serum show that it would not be able to do anything but the electricity, but this" he said motioning to my hands which were actually starting to go back to their original colour and my results would confirm that you are intact a mutant yourself, which is why you survived the serum" I nodded not quite acknowledging it properly "but why now" i asked gesturing to my hands which were now back to normal. "Well the serum has been keeping your body very busy, the mutant inside of you has been fighting it as a foreign body but now that your body is accepting it, the mutation is making its own gifts known." "but I dint know, who did, i can't" my breathing was out of control now and I couldn't calm down my whole body felt like it was burning, my mind on everything that had just been told to me. I was shaking again and the blue was spreading up my arms "Whats happening", i bellowed my body shaking once more, Steve was holding me still trying to sooth me and Bucky had grasped my hand in his and I was squeezing it tightly. An image flashed in my mind and I knew who she was I recognised her my mother how could I have forgotten who she was? "I remember" i cried pushing my face into Bucky cool arm and wrapping my arms around it like I had done as a kid. "I know who my mother is" i choked out. "So do I" doctor banner said turning the screen around for us all to see, staring back at me was Mystique. Doctor Banner walked over and knelt so we were eye level with each other. "Lilly listen to me" he said his voice calm "it would appear your powers are linked to your emotion, when you get angry, upset or scared thats what will set it off" i hooded trying to calm myself.
Some hours later found me still clutching to Bucky's metal arm like a frightened child, we were all awake, my appearance had returned to normal and we were all up on the top floor of the Avengers tower. Everyone knew now and I was terrified of myself, I hated the Serum but I could control it this new side of me was something I had to learn all over again. Bucky's flesh hand had been resting on my own for some time and i dosed off to sleep leaning against him with his arm around me on the sofa.
