This is what would've been like if Jocelyn had twins and only one has been affected. I do not own the Mortal Instruments! Enjoy the story!
~Jocelyn's POV~
I held one of baby boys in my arms while my mother held my other son. "He opened his eyes." my mother said and leaned down to show me my son, who was born a few minutes after my first son, had green eyes and I smiled. I looked down and saw my first born opened his eyes, and I thought I was going to scream after seeing his eyes. They were black, like as if he had no eyes, I prevented myself from screaming at the sight. "Twins?" I hear a voice saying, I looked over to the door to see Valentine standing there, he walked over and smiled at the two baby boys. 'How does he not notice what's wrong with this one?!' I thought to myself. "Jonathon" Valentine said. "This one will be Jonathon." Valentine said as he picked up my son from me and he held him and smiled. "He'll be Christopher." Valentine said as he kissed the forehead of the child my mother was holding. My mother hands me Christopher and she walked out of the room to give us time to admire our new children. "Valentine, don't you see that something's wrong with Johnathon?" I asked after a few minutes of silence. "Wrong? I don't see anything wrong with Jonathon. You're probably just exhausted and need some sleep." Valentine said. I know something is wrong with Johnathon, something terribly wrong. I looked down at Christopher to see he has fallen asleep. "I'll go find another crib for Christopher to sleep in." Valentine said and he went into the nursery to put Johnathon in. Doesn't he know there is something wrong with one of his children?
~Later when Jocelyn returns to the Manor after the Uprising~
I stood in front of my home, and see it's now ashes. I looked around trying to find my parents, and Johnathon and Christopher. I stopped in my tracks to see skeletons, three adult skeletons and two infant skeletons. No. I fell to my knees, and noticed how I started to cry, I lost my family, my children, but still had my unborn child. It was then when I heard a faint cry from somewhere, a cry of a baby. I got to my feet and ran, following the sound of the cry. I heard someone running behind, knowing it was Luke. I stopped dead in the tracks when I see my baby laying in the middle of a field, crying. I ran over and picked him up, and I see those green eyes, Christopher. "Jocelyn!" I hear Luke exclaim when he finally arrived. I held Christopher close and cried, tears of joy that at least I knew one of my children is alive. "Luke, we have to leave." I said turning to Luke. "We can head to Paris and stay there until we figure things out." Luke said and I nodded. We then started to run, I held Christopher the whole time and it took us about 9 days to reach Paris. It was later then when I told Luke that I'm going to America and live there to protect my children from the Shadow world, I never want them to get involved with any of this and return to where I lost my family and Johnathon. They will be protected from the Shadow world, and they will be hidden from the man who I know is still alive.
