Captain Ava, otherwise known as Ava was taken into the capitol when she turned 5. She was nabbed at 4 but despite that she knew every single thing that had happened before then. She remembered her family and everybody around her during that time. That was one of the promising qualities that had triggered the people of the alps to take her and make her one of them. She had promising qualities that would make up a lethal weapon and so they did not waste time in taking her unto their little, rising government.
They saw and charted what the future would look like and that was what facilitated taking her immediately they noticed the stuff she was made of. They knew that any chance wasted would be calamitous to them, so they did everything within that period to get her and make her one of them. Luckily for them she accepted the government into her heart at a very young age and decided not to be a douchebag like the rest of the kids who felt homesick all the time.
