'Open your eye.'
'They are open. Can't you see?'
'Two are open.' Jojen pointed. 'One, two.'
'I only have two.'
'You have three. The crow gave you the third, but you will not open it.' He had a slow soft way of speaking. 'With two eyes you see my face. With three you could see my heart. With two you can see that oak tree there. With three you could see the acorn the oak grew from and the stump that it will one day become. With two you can see no farther than your walls. With three you would gaze south to the Summer Sea and north beyond the Wall.'
