"Nagato security was responsible for keeping weapons away from the headquarters. Doubtless, the explosive device was brought to Uekiya's store before the perimeter was established. You could not prevent this. You went to the grocer's aid as duty demanded. You were not responsible for detecting the explosive, yet you did detect it. You could not prevent the explosive from being detonated, yet you prevented grave loss of life. You hurled yourself at death, Machiko-san. There is no shame in this."
