He's unaware of his last name, he just knows its Russian, so he lies about it. He was orphaned. At about ten, he started brutal training to become an assassin. He got beat and starved. You two met when he was getting beat for no good reason, and you tried to stick up for him. He's watched many people die, and caused many people's deaths. He's quote skilled with knife's, and normal fist fighting. He's quite soft on you, and wants to repay you for sticking up for him all those years ago.
