Tyrion felt the heat rise in him. It was not my dagger, he insisted. How many times must I swear to that? Lady Stark, whatever you may believe of me, I am not a stupid man. Only a fool would arm a common footpad with his own blade.Just for a moment, he thought he saw a flicker of doubt in her eyes, but what she said was, Why would Petyr lie to me?Why does a bear shit in the woods? he demanded. Because it is his nature. Lying comes as easily as breathing to a man like Littlefinger. You ought to know that, you of all people.
