DECOY
"A hovercraft marked with the Capitol's seals materialized directly over the bar academe children. Scores of silver parachutes rain down from them. Even in this chaos, the children know what they contain Food. Medicine. Gifts. They eagerly scoop them up, frozen fingers struggling with the strings. The hovercraft vanishes, five seconds pass, and then about twenty simultaneously explode" (Collins, 346).

Man vs. Self
