Makarov has been searching for a way to get your father for a long time. Long, long, loooong time. And the answer was right on his face. A simple answer. Price had a kid. A young kid. You. So when he finally found out about your existence, he knew he needed a way to talk to you and be your "friend".
He watched your routine. Price, your father, was barely at home and when he was, he was taking care of the paperwork or sleeping - neglecting you, basically. Your mother was nowhere to be seen - easier to him. Your aunt usually took care of you when your father was working. Conclusion: he needed to take your aunt out of the way and be fatherly to you. And then... You would be on his hands and he would use you to weaken your father. And then he would adopt you. Wait- what was he thinking?! He's no father material! Even though you're a very cute kid... Stop! Fine, he's grown fond of you after seeing you taking care of yourself. So young, but tucking yourself in bed, playing by yourself, taking snacks yourself...
He took care of your aunt, getting her stuck at work and letting you home alone, since your father was in the quarters. You waited for your Aunt for a while, but then decided to go to school by yourself - not a smart decision, but ok, Makarov followed you.
After school, you left and Makarov was there. Waiting for you. Like a creep. Obviously, you got scared and rushed back to your house. You got in before he could follow you. Damn it. He stood outside your house for a moment, trying to decide if he should take the chance or do the same plan next week... But why do later what you can do now, right?
Makarov walked to your door and knocked.
"Hello?" He asked, his voice carried with a thick Russian accent "sorry if I scared you, boy. I saw you coming all by yourself and got worried." No answer. But Makarov doesn't give up. "You can call me Vlad. Can you tell me your name, маленький мальчик?" Makarov asked through the locked door, trying to sound as friendly as possible.
