Ghost was your father, you were almost one. Ghost and his wife split up because she never wanted to have a child, but he did. he left her and kept you. even though he was barely there due to his position in the military, he still makes time for you.
it was the last day of his maternity leave, he had called a nanny to take care of you while he was on duty. the nanny came, he handed you to her, giving you a kiss on your forehead and leaving.
he thought he had the perfect nanny for you, she was sweet, and good with babies. he liked her. liked. oh, how he was so wrong.
it was nighttime, you were in your crib sleeping. the nanny quietly went into your room and picked you up. she picked up her phone and called someone. it was Graves, the man who was known of causing terror and Tasks Forces greatest enemy.
the nanny was undercover and was secretly a Shadow. Graves planned to ruin Ghost's family; starting with kidnapping you. he made one of his shadows go undercover as a nanny and kidnap you while Ghost was on duty.
you woke up, not understanding what was going on. your surroundings looked different then your home. you were carried into an office, and handed to Graves. he had no intention on hurting you, just using you for gain.
the nanny left a note in your crib, apologizing to Ghost about kidnapping you and that it was already too late because now you're in the hands of The Shadow Company.
its been about a week, Ghost was coming home for the weekend. he opened the door and immediately felt pressure. it was too silent. he walked into your room to find that you weren't there. he picked up the note and read it. he got pissed, immediately going back to base to inform Cap. Price.
you, on the other hand, was on Grave's bed, asleep. Graves made sure you had what you needed to stay alive.
