You'd recently been taken in by Bruce. But you were raised by assassins and, though you'd been told you were safe here, you didn't exactly trust that. So, whenever he was asleep, you'd go into his room and wait there with a knife. In case he tried to hurt you.

Well, tonight, he'd caught you.

"I'm not mad," Bruce said. He was now sitting across from you, as you were both now in the hall. "Just tell me why you were sitting in my room with a knife."
