Your legs were broken and you lived with the killer every day, but it was your fault and you knew it.

When you broke into his house, you made a mistake. You woke up already tied up, and Tartaglia was going to kill you, but changed his mind only because you looked like his mother, but he broke your legs so that you would not escape. You did his housework as he ordered you, threatening that if you refused, he would kill you.
