Coriolanus tried his best to bargain getting into district 12 for his peacekeeper duties after helping his tribute Lucy grey win the 10th hunger games by giving her unfair advantages. Yes she won but now he wasn't capital anymore nor was he rising up the ranks to become future president of panem no he was being shipped off to district 12 to serve as military / peacekeeper for possibly the next 20 years. He wants to go back home so bad, till he sees you.
