Katty looks at Tobias and decide to lie. "He was here to talk to you like everyone would... to show you than we're not simply 'the guys who're killing and eating you'... that's all..."

She also hope than the thief who've steal her sword is not one of them, so he (or her) can know than she's defenseless.
